Cesar Victora
Prix Canada Gairdner en santé mondiale John Dirks
2017
pour sa contribution exceptionnelle à la santé et à la nutrition maternelle et infantile dans les pays à revenu faible ou intermédiaire, avec un accent particulier sur l’impact de l’allaitement exclusif sur la mortalité infantile et l’impact à long terme de la nutrition au début de la vie
Professeur émérite, Université fédérale de Pelotas, Pelotas, Brésil
Les travaux La carrière du Dr Victora a été consacrée aux facteurs qui influent sur la santé maternelle et infantile dans les pays à revenu faible ou intermédiaire. Il a concentré ses efforts sur les trois grands domaines que sont la santé et la nutrition des enfants, le suivi et l’évaluation des programmes de santé, et l’équité en santé. De retour au Brésil après son doctorat, il a aidé à mettre en place une des plus longues études de cohorte de naissances en cours dans le monde, la cohorte de naissances Pelotas de 1982, dans le cadre de laquelle 6000 personnes ont été suivies jusqu’à aujourd’hui. Ses études ont aidé à établir l’influence des 1000 premiers jours (de la conception jusqu’à l’âge de deux ans) sur les résultats viagers, y compris les maladies chroniques et le capital humain. L’impact La plus grande contribution du Dr Victora à la santé publique a peut-être été les travaux qu’il a menés dans les années 1980, dont une première étude montrant l’importance de l’allaitement exclusif pour la prévention de la mortalité infantile. Ses conclusions ont contribué à des recommandations de politique de l’UNICEF et de l’Organisation mondiale de la Santé visant à inciter les mères à allaiter leurs nourrissons exclusivement pendant les six premiers mois. Plus récemment, ses cohortes de naissance à long terme ont permis de documenter les avantages de l’allaitement sur les plans de l’intelligence, de la scolarisation et du revenu à l’âge adulte, ainsi que les conséquences à long terme d’une sous-alimentation en début de vie. Le Dr Victora a également fait des contributions importantes sur la façon d’évaluer l’impact des programmes de santé sur la mortalité infantile et l’étude des inégalités sociales en matière de santé infantile.

Huda Y Zoghbi
Prix internationaux Canada Gairdner
2017
pour la découverte du fondement génétique du syndrome de Rett et ses conséquences pour les troubles du spectre autistique
Professeure au Collège de médecine Baylor, chercheure à l’Institut médical Howard Hughes et directrice de l’Institut de recherche neurologique Jan et Dan Duncan à l’Hôpital pour enfants du Texas, Houston, Texas, États-Unis
Les travaux Formée comme neurologue pour enfants, la Dre Zoghbi ne pouvait supporter la détresse des enfants atteints de maladies neurologiques dévastatrices, et elle a mené des recherches dans l’espoir d’aider ses patients. Après avoir rencontré des patients atteints du syndrome de Rett, un trouble qui frappe après un an de développement normal et se manifeste par une regression développementale, l’isolement social, la perte de l’usage et les mouvements compulsifs des mains, des convulsions et d’autres symptômes neurocomportementaux, elle a décidé de trouver l’origine génétique de cette maladie. Le plus grand défi qui se posait est que le syndrome de Rett est habituellement un trouble sporadique (un cas dans une famille) dont le génome n’avait été ni cartographié ni séquencé. Sa persévérance a porté fruit car, après des recherches ayant duré 16ans, elle a découvert que le syndrome de Rett est causé par des mutations dans MECP2. La Dre Zoghbi a révélé l’importance de MECP2 dans la fonction de divers sous-types de neurones et mis en évidence la contribution de différents sous-types de neurones dans le cerveau à diverses caractéristiques neuropsychiatriques. Elle a également démontré que le cerveau était extrêmement sensible aux niveaux de MECP2 et qu’un doublement des niveaux de MECP2 provoquait un déficit neurologique progressif chez la souris. Ce trouble est maintenant appelé syndrome de duplication de MECP2 chez les humains. Ses travaux récents ont démontré que les symptômes présents chez des souris adultes modélisant le trouble de la duplication peuvent être inversés en utilisant des oligonucléotides antisens pour normaliser les niveaux de MECP2. L’impact La découverte du gène du syndrome de Rett a fourni un test génétique de diagnostic simple permettant un diagnostic précoce et précis de ce trouble. Elle a également révélé que des mutations de MECP2 peuvent également causer une foule d’autres états neuropsychiatriques allant de l’autisme à la schizophrénie juvénile. En outre, elle a fourni des preuves montrant qu’un trouble du spectre autistique (TSA) ou un trouble de déficience intellectuelle (TDI) peut être d’origine génétique, même s’il est sporadique (non héréditaire). Aujourd’hui, nous savons que des dizaines de TSA et TDI sont causés par de nouvelles mutations sporadiques. En outre, sa découverte a ouvert un nouveau domaine de recherche sur le rôle de l’épigénétique dans les phénotypes neuropsychiatriques. Son utilisation d’un oligonucléotide antisens pour abaisser le taux de MECP2 fournit une stratégie thérapeutique potentielle pour le syndrome de duplication de MECP2, inspirant des études similaires pour d’autres troubles de duplication.

Rino Rappuoli
Prix internationaux Canada Gairdner
2017
pour avoir été à l’avant-garde de l’approche génomique, appelée vaccinologie inverse, ayant servi à développer un vaccin contre le méningocoque B qui a sauvé de nombreuses vies dans le monde entier
Scientifique principal et chef de la R-D externe, GSK Vaccines, Sienne, Italie
Les travaux Le Dr Rappuoli est un pionnier dans le domaine des vaccins et a été à l’origine de plusieurs nouveaux concepts scientifiques. Tout d’abord, il a introduit la notion selon laquelle les toxins bactériennes peuvent être détoxifiées par manipulation génétique (détoxification génétique, 1987). Puis, la notion selon laquelle il est préférable d’étudier les microbes dans le milieu cellulaire où elles interagissent (microbiologie cellulaire, 1996), enfin, l’utilisation de génomes pour developer de nouveaux vaccins (vaccinologie inverse, 2000). Dans le processus de vaccinologie inverse, la séquence génomique complète d’un agent pathogène est passée au crible à l’aide d’outils bioinformatiques pour aider à déterminer quels gènes codent pour quelles protéines, contre lesquelles des vaccins peuvent être développés. L’impact Le Dr Rappuoli a également travaillé sur plusieurs molécules qui ont été intégrées à des vaccins homologués. Il a caractérisé la molécule CRM197, aujourd’hui la plus largement utilisée comme vecteur des vaccins contre Haemophilus influenzae, les méningocoques et les pneumocoques. Subséquemment, il a développé un vaccin contre la coqueluche renfermant la toxine génétiquement détoxifiée de la coqueluche, ainsi que le premier vaccin conjugué contre le méningocoque C qui a permis d’éradiquer la maladie au Royaume-Uni en 2000. Son travail sur la vaccinologie inverse a conduit à l’homologation du premier vaccin contre le méningocoque B approuvé en Europe et au Canada en 2013 et aux États-Unis en 2015.

Lewis E Kay
Prix internationaux Canada Gairdner
2017
pour le développement de la spectroscopie RMN moderne en vue de l’étude de la dynamique et de la fonction des structures biomoléculaires, y compris les applications aux machines moléculaires et aux conformations de protéines rares
Professeur, Départements de génétique moléculaire, de biochimie et de chimie, Université de Toronto, et scientifique principal, Hôpital pour enfants malades, Toronto, Ontario, Canada
Les travaux Le professeur Kay et ses collègues ont apporté des contributions importantes au domaine de la spectroscopie biomoléculaire à résonance magnétique nucléaire (RMN) avec le développement de méthodes servant à « visualiser » les molécules de protéines dans leur solution ambiante naturelle et de recueillir des renseignements sur la façon dont leurs formes évoluent avec le temps, conduisant à une fonction biologique. Ces méthodes ont fait la lumière sur la façon dont les molécules impliquées dans la neurodégénérescence peuvent former des structures anormales qui aboutissent éventuellement à des états pathologiques. En outre, ces travaux nous ont permis de mieux comprendre comment fonctionnent les machines cellulaires et comment les communications entre les différentes parties de ces machines peuvent servir de cibles pour le développement de médicaments dans la lutte contre certains cancers. L’impact Ces recherches ont approfondi notre compréhension de la nature flexible de la structure des protéines et de l’importance de cette flexibilité à la fois pour la fonction et la dysfonction. Cela a ouvert de nouvelles perspectives sur les régions clés des molécules qui pourraient devenir la cible de médicaments. Les méthodes élaborées par le Dr Kay sont employées dans des laboratoires à travers le monde, notamment ceux qui font des recherches sur des maladies telles que le diabète, le cancer et les maladies cardiovasculaires. Les outils mis au point par son groupe de recherche sont diffusés librement et sont largement utilisés dans le monde entier.

David Julius
Prix internationaux Canada Gairdner
2017
pour la détermination du fondement moléculaire de la somatosensation – comment nous ressentons la chaleur, le froid et la douleur
Professeur, président du Département de physiologie et titulaire de la chaire Morris Herzstein en biologie moléculaire et en médecine, UCSF, San Francisco, Californie, États-Unis
Les travaux Le Dr Julius a utilisé des molécules particulières du milieu naturel – dont des toxines de tarentule et de serpent corail, ainsi que la capsaïcine, la molécule qui rend les piments ‘forts’ au goût – pour comprendre comment les signaux responsables des sensations de douleur et de temperature sont transmis au cerveau par des circuits neuronaux. Dans sa recherche, le Dr Julius a concentré ses efforts sur un classe de protéines de canaux ioniques appelées TRP (prononcer « trip ») afin de découvrir comment le composé chimique responsable de la chaleur épicée des piments – appelé capsaïcine – provoque une sensation de brûlure au toucher ou après ingestion. Sa recherche a conduit à l’identification et au clonage de la protéine spécifique en cause, appelée TRPV1. Par ailleurs le Dr Julius a utilisé le menthol, un agent de refroidissement naturel, pour identifier un récepteur du froid « réel ». Cette protéine, appelée TRPM8, est une proche cousine moléculaire de TRPV1, révélant un mécanisme commun de détection de la température. Comme dans le cas de TRPV1, ce canal ionique contribue à une hypersensibilité au froid, tel que celle éprouvée après la chimiothérapie ou avec d’autres types de lésions nerveuses. L’impact La somatosensation, le sens du toucher et de la douleur, agit comme un système d’alerte pour nous protéger contre les blessures. Bien qu’il joue un rôle critique pour notre survie et notre bien- être, ce système peut devenir hypersensible, causant de la douleur chronique. Ces travaux aident à expliquer comment surgissent ces aspects positifs et négatifs de la sensation de la douleur – une notion essentielle à la compréhension de la genèse des syndromes de douleur chronique. Une indication de l’importance de ce travail en médecine est l’intérêt pour les canaux TRP comme cibles potentielles pour une nouvelle génération d’analgésiques.

Frank Plummer
Prix Canada Gairdner Wightman
2016
pour ses recherches pionnières en Afrique en vue de comprendre la transmission du VIH et son leadership au Laboratoire national de microbiologie du Canada, où il a joué un rôle essentiel dans la lutte contre les épidémies de SRAS, de grippe et d’Ebola
Conseiller spécial auprès de l’administrateur en chef de la santé publique, Agence de la santé publique du Canada;, professeur émérite de microbiologie médicale, Faculté de médecine et Faculté des sciences de la santé, Université du Manitoba, et ancien titulaire de la chaire de recherche du Canada de niveau 1 sur la résistance et la sensibilité aux infections (de 2001 à 2014).

Les travaux : Dans les années 1980, le VIH/sida était largement considéré comme une maladie frappant les homosexuels. Tout au long des années 1980, le Dr Frank Plummer a mené des recherches, facilitées par l’Université du Manitoba, sur une vaste cohorte de travailleuses du sexe de Nairobi, qui ont révélé que les deux tiers avaient le VIH/sida, un résultat étonnant à l’époque. Il a également montré que près de 10 % de ces travailleuses du sexe n’étaient pas infectées par le VIH, malgré de multiples expositions. L’observation d’une résistance naturelle au VIH a guidé les stratégies de développement de vaccins. Le Dr Plummer a poursuivi en faisant des recherches sur les mécanismes de résistance au VIH, les facteurs de risque de transmission hétérosexuelle du VIH et la transmission du VIH de la mère à l’enfant, et il a élaboré des stratégies de santé publique pour lutter contre les infections sexuellement transmissibles. Des recherches subséquentes ont montré qu’en plus de ces travailleuses du sexe, de nombreux groupes sont immunisés contre le VIH. Au cours des 16 années suivantes, le Dr Plummer est resté à Nairobi, et cela a conduit à une série d’études, de collaborations internationales et de certaines découvertes fondamentales sur la susceptibilité à l’infection et la transmissibilité du VIH. L’impact : Ses contributions originales et soutenues dans ce domaine ont débouché sur des stratégies novatrices de prévention du VIH internationalement reconnues qui sont employées dans le monde entier pour prévenir des milliers d’infections au VIH. Professeur émérite à l’Université du Manitoba, le Dr Plummer a fait œuvre de pionnier dans la recherche sur le VIH/sida grâce non seulement à ses travaux novateurs mais aussi à son leadership à titre de directeur scientifique du Laboratoire national de microbiologie à Winnipeg, où il a mené la réponse à de nombreuses épidémies, notamment par son soutien et son apport au développement des programmes de vaccination contre l’Ebola au Canada, au traitement du SRAS en 2003 et à la pandémie de grippe H1N1 en 2009.

pour ses nombreuses contributions pionnières à notre compréhension des infections au VIH et son leadership extraordinaire pour assurer la réussite du traitement de cette maladie dans le monde en développement
Directeur, Institut national des allergies et des maladies infectieuses, National Institutes of Health, Bethesda, Maryland, États-Unis.
Les travaux : Le Dr Fauci a fait une contribution essentielle à la compréhension de la façon dont le VIH détruit les défenses immunitaires du corps. Sa recherche pionnière sur les mécanismes de la maladie et ses travaux sur le développement et l’essai de traitements médicamenteux ont eu une grande influence sur l’établissement des bases scientifiques des modalités de prévention et de traitement efficaces pour les patients vivant avec le VIH/sida. L’impact : Comme preuve de ses réalisations extraordinaires en recherche, le Dr Fauci a été classé dans une analyse faite en 2015 des citations de Google Scholar au 14e rang des chercheurs les plus cités de tous les temps, morts ou vivants, dans un domaine particulier. Outre ses contributions individuelles à la science, le Dr Fauci a servi comme directeur du National Institute of Allergy and Infectious Diseases (NIAID) pendant 32 ans. À ce titre, il a été une force motrice et un leader intellectuel de la réponse de la recherche biomédicale aux maladies infectieuses qui ont dévasté de nombreuses régions du monde en développement. Il a joué un rôle de premier plan en amenant le gouvernement américain à appuyer et à diriger les efforts de recherche qui ont conduit à la mise au point de combinaisons médicamenteuses antirétrovirales qui ont transformé la vie des personnes infectées par le VIH, offrant à plusieurs d’entre elles une espérance de vie essentiellement normale. L’une des réalisations les plus importantes du Dr Fauci a été son rôle en tant qu’architecte principal du Plan d’urgence du président américain pour la lutte contre le sida (PEPFAR) qui, au cours des 13 dernières années, a permis de sauver la vie de millions de personnes atteintes du VIH et de prévenir des millions de cas d’infection au VIH dans le monde en développement, en particulier en Afrique subsaharienne.

Feng Zhang
Prix internationaux Canada Gairdner
2016
pour le développement de CRISPR-Cas comme outil d’édition génomique pour les cellules eucaryotes
Membre principal, Broad Institute of MIT and Harvard, chercheur, McGovern Institute for Brain Research, Massachusetts Institute of Technology, professeur W.M. Keck de développement de carrière en génie biomédical, Départements des sciences du cerveau et de la cognition et de génie biologique, Massachusetts Institute of Technology, Cambridge, Massachusetts, et chercheur Robertson, New York Stem Cell Foundation, États-Unis.
Les travaux : Le Dr Zhang et son équipe ont été les premiers à développer le système CRISPR-Cas microbien comme outil d’édition génomique fonctionnant dans les cellules eucaryotes. Ils ont démontré que l’enzyme Cas9 pouvait être utilisée pour apporter des modifications à plusieurs sites du génome de cellules humaines et de souris, et que les coupes faites à l’aide de l’enzyme Cas9 peuvent être réparées en incorporant un nouveau segment d’ADN. À la suite de ces travaux initiaux, le Dr Zhang et ses collègues ont développé diverses applications pour l’étude de la biologie et de la maladie basée sur la technologie CRISPR-Cas et ils ont découvert d’autres enzymes Cas ayant des propriétés uniques, ce qui a enrichi la trousse d’édition génomique. L’impact : Les outils CRISPR-Cas sont beaucoup plus faciles et moins coûteux à utiliser que les méthodes antérieures d’édition du génome et ils sont employés par des dizaines de milliers de scientifiques partout dans le monde afin d’accélérer les recherches. En définitive, les technologies CRISPR-Cas pourraient ouvrir une avenue thérapeutique efficace pour le traitement de maladies humaines en permettant de neutraliser des mutations nuisibles.

Jennifer Doudna
Prix internationaux Canada Gairdner
2016
pour le développement de CRISPR-Cas comme outil d’édition génomique pour les cellules eucaryotes
Titulaire de la chaire Li Ka Shing du chancelier en recherche biomédicale et en sciences de la santé, professeure de biologie moléculaire et cellulaire et professeure de chimie, Université de Berkeley, et chercheure, Institut médical Howard Hughes, Berkeley, Californie, États-Unis.

Les travaux : En 2012, la Dre Charpentier et la Dre Doudna ont publié la description d’une nouvelle technologie révolutionnaire d’édition génomique qui utilise un ARN à guide unique conçu conjointement avec l’enzyme Cas9 de clivage de l’ADN pour manipuler facilement l’ADN génomique de cellules individuelles. La technologie CRISPR-Cas9 a fourni aux biologistes l’équivalent d’une trousse de chirurgie moléculaire pour inhiber, activer ou altérer facilement des gènes avec une efficacité et une précision élevées. Leur travail a collectivement mené à la découverte révolutionnaire du clivage de l’ADN au moyen de l’enzyme Cas9, une enzyme double guidée par l’ARN dont la capacité à couper l’ADN à double brin peut être programmée en modifiant la séquence de guidage de l’ARN. Reconnaissant qu’une telle activité pourrait être utilisée comme instrument moléculaire pour l’ingénierie de précision du génome de divers types de cellules, leurs équipes ont reconfiguré le guide naturel double de l’ARN en ARN à guide unique (ARNgu), créant un système à deux composantes facile à utiliser. L’impact : Cette technologie transforme les domaines de la génétique moléculaire, de la génomique, de l’agriculture et de la biologie environnementale. Les complexes Cas9 guidés par l’ARN sont des agents d’ingénierie efficaces des génomes chez les animaux, les plantes, les champignons et les bactéries. La technologie CRISPR-Cas9 est utilisée dans des milliers de laboratoires à travers le monde pour faire avancer la recherche biologique grâce à une ingénierie précise des cellules et des organismes.

Philippe Horvath
Prix internationaux Canada Gairdner
2016
établi et caractérisé le système de défense immunitaire bactérien CRISPR-Cas
Scientifique principal, DuPont, Dangé-Saint-Romain, France
Les travaux : La recherche du Dr Barrangou et du Dr Horvath a porté sur la compréhension de la base génétique des propriétés favorables à la santé et technologiques de bactéries bénéfiques utilisées dans les fermentations alimentaires. Avec leurs collègues, ils ont établi que le système CRISPR-Cas offre une immunité adaptative contre les virus dans les bactéries, où il reconnaît l’ADN étranger et utilise un scalpel moléculaire spécial pour le cibler et le détruire. Ils ont également démontré que les faisceaux CRISPR capturent l’ADN viral pour la vaccination naturelle contre les bactériophages. Enfin, ils ont démontré que les gènes cas sont impliqués dans le ciblage de séquences spécifiques et le clivage de l’ADN. L’impact : Leur découverte a établi les CRISPR-Cas en tant que système immunitaire adaptatif des bactéries et a eu un profond impact sur le milieu scientifique, ouvrant la voie à un nouveau champ de recherche. Cela a incité d’autres chercheurs à étudier les CRISPR plus attentivement. Les principaux avantages du système CRISPR par rapport à d’autres techniques d’édition génomique est sa rapidité, sa précision, son efficacité et son coût relativement bas. Et, comme la communauté scientifique l’a démontré au cours des dernières années, il est transférable à de nombreux types d’organismes vivants. La liste des applications possibles comprend l’édition génomique, la production antibactérienne et antimicrobienne, la sécurité alimentaire, la production alimentaire et la sélection végétale.

Yoshinori Ohsumi
PHD
Prix internationaux Canada Gairdner
2015
Array
Pour ses travaux pionniers sur l’élucidation moléculaire d’autophagie, un système de dégradation intracellulaire essentiel qui, déréglé, est lié à de nombreuses maladies, y compris la neurodégénérescence, le cancer et l’infection
Professeur honoraire, Frontier Research Center, Institut de technologie de Tokyo (Tokyo Tech), Tokyo, Japon
Les travaux : M. Ohsumi a été la première personne à observer visuellement la fonction de l’autophagie (auto-alimentation), par lequel les cellules nettoient leurs déchets internes, en tuant les organismes envahisseurs et en maintenant un environnement cellulaire sain. Cette fonction opère comme un système de recyclage cellulaire servant à maintenir l’homéostasie dans le corps. Il a ensuite précisé le mécanisme de l’autophagie et les gènes en cause. L’impact : L’autophagie est maintenant considérée comme un système de recyclage cellulaire vital qui pourrait se révéler utile dans le développement futur de traitements pour les maladies neurodégénératives telles que l’Alzheimer, le cancer et d’autres troubles liés au vieillissement. Les résultats de la recherche du professeur Ohsumi ont depuis été appliqués aussi à l’autophagie chez les animaux, et de nombreux chercheurs travaillent maintenant à préciser davantage le mécanisme moléculaire et la signification physiologique de ce processus.

Michael N. Hall
PHD
Prix internationaux Canada Gairdner
2015
Pour sa découverte de la protéine kinase TOR activée par des nutriments et l’élucidation de son contrôle central de la croissance cellulaire, essentielle au développement et au vieillissement et largement impliquée dans les cancers, le diabète et les maladies cardiovasculaires et immunitaires
Michael N. Hall est né (1953) à Porto Rico et a grandi en Amérique du Sud (Venezuela et Pérou). Il a obtenu son doctorat de l’Université Harvard et a été boursier postdoctoral à l’Institut Pasteur (Paris, France) et à l’Université de Californie, San Francisco. Il a rejoint le Biozentrum de l’Université de Bâle (Suisse) en 1987 où il est actuellement professeur et ancien président du département de biochimie. Michael Hall est un pionnier des domaines de la signalisation TOR et du contrôle de la croissance cellulaire. En 1991, Mr Hall et ses collègues ont découvert la TOR (cible de la rapamycine), et ont subséquemment élucidés son rôle de contrôleur central de la croissance cellulaire et du métabolisme. La TOR est une protéine kinase conservée activée par l’insuline et des nutriments. La découverte de la TOR a conduit à une évolution fondamentale de la façon dont nous concevons la croissance cellulaire. Celle-ci n’est pas un processus spontané qui se déroule uniquement lorsque les blocs de construction (nutriments) sont disponibles, mais plutôt un processus plastique étroitement réglementé, contrôlé par des voies de signalisation dépendantes de la TOR. En tant que contrôleur central de la croissance cellulaire et du métabolisme, la TOR joue un rôle clé dans le développement et le vieillissement, et elle est impliquée dans des troubles tels que le cancer, les maladies cardiovasculaires, le diabète et l’obésité. Michael Hall est membre de l’Académie nationale des sciences des États-Unis, et il a reçu de nombreuses récompenses, dont le Prix Cloëtta pour la recherche biomédicale (2003), le Prix Louis-Jeantet de médecine (2009), le Prix Marcel Benoist pour les sciences ou les sciences humaines (2012) et le Prix Breakthrough in Life Sciences (2014). Il a siégé à plusieurs conseils consultatifs éditoriaux et scientifiques. Il vit avec son épouse Sabine (née Carrère) et leurs filles Zoé et Léa, à Bâle.

La professeure Maquat est connue pour ses études des cellules de mammifères sur la dégradation des ARN messagères à médiation non-sens (NMD), dont elle a fait rapport pour la première fois en 1981 par le biais d’études sur l’anémie hémolytique bo-thalassémique, à partir desquelles elle a par la suite découvert la ronde pionnière de traduction, le complexe de jonction exon (EJC), et comment l’EJC marque les ARNm pour un premier cycle de traduction de contrôle de la qualité qui se produit en grande partie lorsque les ARN messagères comme nouvellement synthétisées entrent dans le cytoplasme. Elle continue à faire des contributions fondamentales sur les mécanismes de la NMD et d’une autre voie qu’elle a découverte et nommée dégradation des ARNm à médiation Staufen (SMD). Son travail sur la SMD a défini de nouveaux rôles pour les longs ARN non-codants et de petits éléments intercalés chez les humains et les rongeurs, dévoilant la complexité des interactions ARN-ARN qui comprennent d’importantes voies de régulation géniques post-transcriptionnelles au cours du développement et de la différenciation des cellules de mammifères. La professeure Maquat a siégé à des comités de rédaction, y compris ceux de RNA, Mol. Cell Biol., RNA Biol. et Methods, comme administratrice, trésorière/secrétaire et présidente élue de la RNA Society, comme membre du Comité d’information publique de l’American Society for Cell Biology, et comme présidente de la section des études des NIH.

2014
Pour sa découverte du facteur de croissance vasculaire endothélial (FCVE), un médiateur moléculaire clé dans la formation des nouveaux vaisseaux sanguins, et le développement d’une thérapie anti-FCVE efficace contre le cancer et la dégénérescence maculaire humide
Professeur émérite Mallinckrodt, Beth Israel Deaconess Medical Center, École de médecine de l’Université Harvard

Le Dr Harold F. Dvorak est directeur fondateur du Centre de recherche en biologie vasculaire (CVBR) au Beth Israël Deaconess Medical Center (BIDMC) et professeur émérite Mallinckrodt de pathologie à l’École de médecine de l’Université Harvard. En 1983, le Dr Dvorak et ses collègues ont été les premiers à démontrer que les cellules tumorales sécrétaient un facteur de croissance vasculaire endothélial (FCVE), appelé à l’époque facteur de perméabilité vasculaire ou VPF. Cette découverte fondamentale a fourni le fondement moléculaire pour le domaine de l’angiogenèse. Le Dr Dvorak a ensuite fait l’observation extrêmement importante que les tumeurs se comportent comme des « plaies qui ne guérissent pas » car les réponses vasculaires et stromales qu’elles induisent imitent étroitement celles de la guérison des plaies. Plus récemment, son travail a caractérisé les différents types de vaisseaux sanguins que les tumeurs génèrent et les mécanismes moléculaires par lesquels ils se forment. Le Dr Dvorak a enseigné pendant de nombreuses années à l’École de médecine de l’Université Harvard et a souvent prononcé des allocutions comme professeur invité ainsi qu’à de nombreuses conférences scientifiques nationales et internationales. Il est membre de l’Association américaine pour l’avancement de la science et de la Fondation nationale pour la recherche sur le cancer et il a servi comme président de l’American Society for Investigative Pathology, laquelle lui a décerné le Prix Rous-Whipple 2002, et, en 2013, le Prix de la canne au pommeau d’or pour ses réalisations scientifiques. En 2005, il a reçu le Grand Prix Lefoulon-Delalande de l’Institut de France et, en 2006, le premier Prix Albert Szent-Györgyi pour le progrès dans la recherche sur le cancer, de la Fondation nationale pour la recherche sur le cancer (NFCR). Formé à l’Université de Princeton et à l’École de médecine de l’Université Harvard, il a été résident en pathologie à l’Hôpital général du Massachusetts et a fait des recherches postdoctorales aux National Institutes of Health. Il est membre du corps professoral de l’École de médecine de l’Université Harvard depuis 1967 et attaché au BIDMC depuis 1979. Suivant son départ après 26 ans comme président de la pathologie au BIDMC en juillet 2005, le Dr. Dvorak a consacré ses efforts à l’édification du CVBR, tout en poursuivant ses recherches.

Pour sa découverte d’une thérapie anti-TNF dans le traitement de la polyarthrite rhumatoïde et d’autres maladies inflammatoires
Chef, Institut de rhumatologie Kennedy, Département d’orthopédie, de rhumatologie et de sciences musculosquelettiques, Université d’Oxford
Après une formation en médecine et constatant que la recherche était la voie vers l’amélioration de la thérapie, il a étudié en vue d’obtenir un doctorat en immunologie à l’Institut Walter et Eliza Hall de Melbourne auprès du professeur Sir Gus Nossal. Il a appris à optimiser les réponses immunitaires en culture de tissus et a également étudié de puissants médiateurs intercellulaires, des molécules éventuellement identifiées comme les cytokines, l’auto-immunité et l’immunorégulation. En 1983, tout en travaillant à l’Unité d’immunologie tumorale d’Av Mitchison à l’ICRF, au Collège universitaire de Londres, et en réfléchissant aux nouvelles observations sur le CMH de classe II régulé positivement dans les sites locaux d’auto-immunité (p. ex. la thyroïde), il a émis l’hypothèse que cela reflétait une augmentation de la présentation d’antigène. Étant donné que les cytokines, notamment les interférons, régulent positivement les antigènes CMH, il a émis en 1983 l’hypothèse que la présentation de cytokines et d’antigènes régulées positivement est une étape clé dans l’apparition d’une maladie auto-immune chronique. Il s’agissait d’une hypothèse vérifiable, et celle-ci a été vérifiée avec succès sur la thyroïdite de Grave vers 1985-1986. Cela a mené à une collaboration avec Ravinder Maini, un déménagement à l’Institut Kennedy et l’étude de ce qui constituaient les cytokines critiques dans la maladie auto-immune humaine la plus accessible, la polyarthrite rhumatoïde. De nouvelles méthodes ont été élaborées pour évaluer quelles cytokines sont produites localement, faisant ressortir que de nombreuses cytokines pro-inflammatoires sont produites. Afin de déterminer ce qui constituait la meilleure cible, il a analysé la régulation des cytokines dans le tissu synovial dissocié de la polyarthrite rhumatoïde et trouvé que le blocage de la TNF régulait à la baisse l’IL-1 et d’autres cytokines pro-inflammatoires, ce qui indique que la TNF était la cible thérapeutique longuement recherchée. Cela a été validé dans l’arthrite de la souris, avec un traitement administré après l’apparition de la maladie. Il était donc justifié de procéder à un essai clinique de validation de principe de la thérapie anti-TNF, et Sir Marc a été un chef de file, avec son collègue le professeur Sir Ravinder Maini, de cet essai et d’autres essais cliniques subséquents qui ont conduit à l’approbation de la thérapie anti-TNF pour la polyarthrite rhumatoïde. Cette réussite et celles des essais d’autres anticorps contre la TNF ont fait en sorte que les anti-TNF ont été la classe de médicaments la plus vendue à partir de 2012. Sir Marc a succédé à Ravinder Maini au poste de directeur de l’Institut de rhumatologie Kennedy en 2002. Ces travaux ont mené à son élection à diverses académies nationales des sciences (p. ex., la Société royale, l’Académie australienne des sciences et l’Académie nationale des sciences des États-Unis, et à l’obtention de plusieurs prix prestigieux, la plupart du temps avec son collègue Sir Ravinder Maini, par exemple le Prix Crafoord de l’Académie royale de Suède, le Prix Albert Lasker de recherche médicale clinique, le Prix Ernst Schering et le Prix Paul Janssen.

Pour son leadership exceptionnel dans les essais cliniques mondiaux et les études de population sur les maladies cardiovasculaires, qui ont façonné les meilleures lignes directrices en matière de prévention et de traitement
Professeur de médecine et directeur exécutif, Institut de recherche en santé de la population, Université McMaster, et vice-président à la recherche, Hamilton Health Sciences

Les travaux de Salim Yusuf, qui se sont poursuivis sur plus de 35 ans, ont considérablement influencé la prévention et le traitement des maladies cardiovasculaires à l’échelle mondiale. Diplômé en médecine à Bangalore en 1976, il a obtenu une bourse Rhodes et reçu un doctorat en philosophie de l’Université d’Oxford. À cette époque, en collaboration avec Richard Peto et Peter Sleight, il a élaboré les concepts des grands essais simples et des méta-analyses. Il a coordonné l’essai ISIS (qui a établi la structure pour les futurs travaux de collaboration internationale sur les maladies cardiovasculaires) démontrant le rôle des bêtabloquants pour l’infarctus du myocarde, et a siégé au comité de direction de tous les essais subséquents dans le cadre de l’ISIS. En 1984, il s’est joint aux National Institutes of Health, à Bethesda, aux États-Unis, où il a été un chef de file dans l’essai SOLVD (établissant l’utilité des inhibiteurs de l’ECA pour la dysfonction LV) et l’essai DIG (visant à clarifier le rôle de la digitaline). En 1992, il est passé à l’Université McMaster, où il a mis sur pied un programme international de recherche sur les maladies cardiovasculaires et la prévention, qui a mené à la création de l’Institut de recherche en santé de la population, qu’il dirige toujours. Ses essais thérapeutiques ont permis de préciser le rôle des inhibiteurs de l’ECA dans la prévention des maladies cardiovasculaires (étude HOPE), des bithérapies antiplaquettaires des syndromes coronariens aigus (étude CURE), ainsi que le rôle des nouveaux antithrombotiques et des interventions invasives. L’IRSP a récemment été cité par SCImago comme étant l’établissement canadien ayant le plus grand impact et le 7ème plus important à ce chapitre dans le monde. Les travaux épidémiologiques du Dr Yusuf ont été menés dans plus de 60 pays, sur tous les continents habités, et ont démontré que la majorité des risques de maladie cardiovasculaire et cérébrovasculaire est attribuable au même petit groupe de facteurs de risque. Le Dr Yusuf dirige actuellement la plus grande étude jamais entreprise sur le rôle des changements sociétaux dans les MCV qui rejoint 155 000 personnes dans 700 collectivités de 22 pays à revenu élevé, intermédiaire ou faible. Ces études ont conduit à une meilleure compréhension de l’influence des changements sociétaux sur les comportements et les facteurs de risque, et la façon dont ils entraînent des maladies cardiovasculaires. Au cours des trois dernières décennies, il a contribué à renforcer les capacités de recherche clinique et d’étude de population à travers le Canada (d’abord au sein de la Collaboration canadienne de cardiologie et, plus récemment, de CANNeCTIN) et dans le monde en établissant des réseaux regroupant plus de 1500 sites dans 85 pays sur tous les continents habités. Il a formé plus de 50 chercheurs, dont plusieurs sont devenus des chefs de file nationaux ou internationaux reconnus en recherche médicale. Il a contribué au développement d’établissements ou de grands programmes de recherche au Canada, en Inde, en Argentine, au Brésil, en Afrique du Sud, en Arabie saoudite, en Malaisie et en Chine. Il détient une chaire de la Fondation des maladies du cœur de l’Ontario, et a été chercheur principal des Instituts de recherche en santé du Canada (1999-2004). Il a reçu plus de 35 prix nationaux et internationaux en recherche, il a été intronisé au sein de la Société royale du Canada, nommé officier de l’Ordre du Canada et, en 2014, intronisé au Temple de la renommée médicale canadienne. Le Dr Yusuf a publié plus de 800 articles dans des revues soumises à l’examen de pairs, devenant le deuxième chercheur le plus cité dans le monde en 2011. Il est président élu de la Fédération mondiale du cœur, où il a lancé un programme de chefs de file émergents dans 100 pays en vue de réduire de moitié le fardeau des maladies cardiovasculaires à l’échelle mondiale d’ici une génération.

Harvey J. Alter
MD
Prix internationaux Canada Gairdner
2013
Pour sa contribution essentielle à la découverte et l’isolement du virus de l’hépatite C, qui a conduit au développement de nouveaux agents diagnostiques et thérapeutiques
Chercheur principal, chef de la section des maladies infectieuses et directeur adjoint de la recherche, Département de médecine transfusionnelle, Institut national de la santé, Bethesda, Maryland, É.-U.

Le Dr Harvey Alter a obtenu son diplôme de médecin à la Faculté de médecine de l’Université de Rochester et a acquis une formation en médecine interne à l’Hôpital Strong Memorial et à l’Hôpital de l’Université de Washington, à Seattle. En 1961, il s’est joint aux National Institutes of Health (NIH) comme associé-clinicien. Il a ensuite passé plusieurs années à l’Université de Georgetown, retournant aux NIH en 1969 comme chercheur principal au Département de médecine transfusionnelle du Centre clinique, où il est devenu par la suite chef des études cliniques et directeur adjoint de la recherche. Le Dr Alter a co-découvert l’antigène d’Australie, un élément clé dans la détection du virus de l’hépatite B. Subséquemment, le Dr Alter a dirigé un projet au Centre clinique des NIH qui a mené à la création d’un entrepôt d’échantillons de sang utilisés pour découvrir les causes de la transmission de l’hépatite lors d’une transfusion et en réduire les risques. Il a été chercheur principal dans le cadre des études qui ont identifié l’hépatite autre que A et B, aujourd’hui appelée l’hépatite C. Son travail a contribué à établir le fondement scientifique des programmes de dépistage des donneurs de sang, qui ont réduit l’incidence de l’hépatite post-transfusionnelle à près de zéro. Le Dr Alter a reçu le Prix clinique Lasker en 2000. En 2002, il est devenu le premier scientifique du Centre clinique des NIH à être élu à l’Académie nationale des sciences (NAS). La même année, le Dr Alter a été élu à l’Institut de médecine.

Daniel W. Bradley
PHD
Prix internationaux Canada Gairdner
2013
Pour une contribution essentielle à la découverte et l’isolement du virus de l’hépatite C, qui a conduit au développement de nouveaux agents diagnostiques et thérapeutiques
Center for Disease Control (retraité), consultant en ID, Atlanta, Géorgie, É.-U.

Après avoir obtenu son diplôme de l’Université de San Jose, en 1964, le Dr Bradley a été recruté par le Service de santé publique des États-Unis (USPHS) afin d’élaborer des méthodes de détection de toute une variété de composés cancérigènes dans l’atmosphère, une tâche particulièrement dangereuse. À la fin de son service au USPHS, il a poursuivi ses études et obtenu un diplôme de maîtrise en biochimie de l’Université de la Californie et un doctorat de l’Université de l’Arizona. En 1971, il a été embauché par le Center for Disease Control (CDC) à Phoenix, en Arizona, pour étudier la possibilité que l’acide ascorbique abrège la durée des infections virales respiratoires. Ne pouvant observer un tel avantage, le Dr Bradley a ensuite centré ses efforts sur le virus de l’hépatite A et B, étudiant leur infectivité chez les primates non-humains. Ces études se sont déroulées entre 1972 et 1975 et ont conduit à l’identification d’un nouveau groupe de virus de l’hépatite. En 1975, son laboratoire a été contacté par un scientifique de Hyland Laboratories qui s’intéressait à l’identification possible d’un virus responsable de l’hépatite autre que A ou B chez plusieurs patients hémophiles. D’autres études menées dans les années 1970 et 1980 ont révélé la présence d’un flavivirus, ce qui a conduit à l’identification précoce de ce qui est maintenant connu comme le virus de l’hépatite C (VHC). Bien qu’un fragment du génome du VHC ait été identifié en 1987, l’annonce publique du clonage réussi du VHC n’est survenue qu’en 1989.

Thomas M. Jessell
PHD
Prix internationaux Canada Gairdner
2012
Pour sa recherche sur la définition des voies génétiques et moléculaires conduisant à l’élaboration complexe de la moelle épinière, avec des implications en vue d’applications thérapeutiques
Howard Hughes Medical Institute, Kavli Institute for Brain Sciences, Centre médical de l’Université Columbia, New York
Le défi : Le système nerveux envoie des signaux à partir de notre cerveau à différentes parties de notre corps par l’intermédiaire de circuits. Cela nous permet de voir, de nous déplacer et de gérer nos pensées. Cependant, une paralysie accidentelle ou une maladie neurodégénérative vient perturber ces circuits. Le travail : Le Dr Jessell a découvert des voies génétiques et moléculaires conduisant au développement complexe de la moelle épinière. Cela améliore notre compréhension de la façon dont notre système nerveux communique. Pourquoi cela est important : En comprenant comment les neurones sensoriels et les motoneurones communiquent, nous pouvons réparer les circuits endommagés et traiter ou guérir des lésions traumatiques causées par des maladies telles que la SLA, les accidents vasculaires cérébraux ou une blessure à la moelle épinière. Tom Jessell est professeur Claire Tow aux départements de neurosciences, de biochimie et de biophysique moléculaire de l’Université Columbia. Il est également codirecteur du Kavli Institute for Brain Sciences et de la Mind Brain Behaviour Initiative. Depuis 1985, le Dr Jessell est chercheur au Howard Hughes Medical Institute. Le Dr Jessell est membre de la Royal Society et de l’Académie britannique des sciences médicales, et il est associé étranger de l’Académie nationale des sciences et membre de l’Institut de médecine des États-Unis. En 2008, le Dr Jessell a été co-lauréat du Prix inaugural Kavli en neurosciences. Il a également reçu de nombreux autres prix.

Michael W. Young
PHD
Prix internationaux Canada Gairdner
2012
Pour ses découvertes révolutionnaires concernant l’horloge biologique responsable des rythmes circadiens
Professeur Richard et Jeanne Fisher, vice-président des Affaires académiques et chef du Laboratoire de génétique à l’Université Rockefeller, New York, N.Y.
Le défi : Comment notre horloge biologique interne guide-t-elle notre corps toute la journée? Le travail : Avec les Drs Michael Rosbash et Jeffrey Hall, le Dr Michael Young a découvert que nos horloges circadiennes sont contrôlées par un petit groupe de gènes qui travaillent au niveau de la cellule individuelle. Des mutations subtiles dans l’un de ces gènes peuvent accélérer ou ralentir nos rythmes quotidiens. Pourquoi cela est important : Leurs découvertes au sujet de l’horloge biologique ont des applications pour les troubles du sommeil et de l’appétit. Elles ont également des applications pour des organes tels que le cerveau, le foie, les poumons et la peau, qui utilisent les mêmes mécanismes génétiques pour contrôler leurs activités rythmiques. Le Dr Young a obtenu un doctorat en génétique de l’Université du Texas (1975). Il a fait un stage postdoctoral à l’Université Stanford avant de passer à l’Université Rockefeller. En 1991, il est devenu chef de l’unité du Science and Technology Center for Biological Timing, de la National Science Foundation, à l’Université Rockefeller. Il a été nommé vice-président des Affaires académiques (2004) et professeur Richard et Jeanne Fisher la même année. Son travail à l’Université Rockefeller a mis l’accent sur deux domaines : le développement neuromusculaire – découlant de l’isolement en laboratoire et de l’étude du locus Notch de la Drosophile – et la génétique du comportement, particulièrement les rythmes circadiens (y compris le clonage initial du gène de l’horloge biologique de la drosophile, la découverte et les caractérisations fonctionnelles des gènes de l’horloge circadienne intemporels, double-temps, ‘shaggy’, vrille et PDP1, et la modélisation des principales caractéristiques moléculaires du système circadien de la drosophile). Le Dr Young a été chercheur au Howard Hughes Medical Institute (1987 à 1996); il est membre de l’Académie nationale des sciences et de l’Académie américaine de microbiologie. Parmi les distinctions qu’a reçues le Dr Young, il y a le Prix en neuroscience 2009 de la Fondation Pierre et Patricia Gruber et le Prix Louisa Gross Horwitz de l’Université Columbia en 2011.

Professeur émérite de biologie, Université Brandeis, Waltham, MA
Le défi : Comment notre horloge biologique interne guide-t-elle notre corps toute la journée? Le travail : Avec les Drs Michael Rosbash et Michael Young, le Dr Hall a découvert que nos horloges circadiennes sont contrôlées par un petit groupe de gènes qui travaillent au niveau de la cellule individuelle. Des mutations subtiles dans l’un de ces gènes peuvent accélérer ou ralentir nos rythmes quotidiens. Pourquoi cela est important : Leurs découvertes au sujet de l’horloge biologique ont des applications pour les troubles du sommeil et de l’appétit. Elles ont également des applications pour des organes tels que le cerveau, le foie, les poumons et la peau, qui utilisent les mêmes mécanismes génétiques pour contrôler leurs activités rythmiques. Jeffrey Hall a obtenu un doctorat en génétique de l’Université de Washington et a été membre du corps professoral de l’Université Brandeis de 1974 à 2007. Tout au long de sa carrière de chercheur, le Dr Hall s’est intéressé à la génétique de la drosophile. Il a travaillé dans les laboratoires de son conseiller au niveau du premier cycle, Philip Ives, de son conseiller au niveau des études supérieures, Laurence M. Sandler, et de son conseiller postdoctoral à l’Institut de technologie de la Californie, Seymour Benzer (le premier à avoir montré que les gènes déterminent le cycle jour-nuit de l’activité des mouches à fruits). En particulier, le Dr Hall s’est intéressé aux fondements neurobiologiques des comportements liés à la parade nuptiale chez la drosophile. Le Dr Hall est membre de l’Académie américaine des arts et des sciences et de l’Académie nationale des sciences. Il a reçu la médaille de la Genetics Society of America (2003) et le Prix en neuroscience de la Fondation Pierre et Patricia Gruber en 2009, avec Michael Rosbash et Michael Young.

Brian M. Greenwood
MD
Prix Canada Gairdner en santé mondiale John Dirks
2012
Pour sa contribution à la réduction significative de la mortalité infantile causée par la méningite et les infections respiratoires aiguës et pour sa contribution à la prévention du paludisme
London School of Hygiene and Tropical Medicine, Londres, Royaume-Uni

Le défi : La méningite, la pneumonie et le paludisme – tous dictés par le climat saisonnier – tuent des millions d’enfants dans le monde en développement chaque année. Le travail : Le paludisme est très répandu au cours de la saison des pluies. Le Dr Greenwood a démontré la valeur des moustiquaires de lit enduites d’insecticide et le traitement à l’aide de médicaments dans la prévention du paludisme. La pneumonie et la méningite sont plus répandues au cours de la saison sèche. Le Dr Greenwood a mis au point et testé deux groupes de vaccins contre ces infections, qui se sont révélés très efficaces pour sauver des vies d’enfants. Pourquoi cela est important : Le Dr Greenwood a été un promoteur infatigable de la santé des enfants dans les pays en développement en combattant la propagation de la maladie et en formant des scientifiques postdoctoraux en Afrique. Brian Greenwood a étudié la médecine à Cambridge (1962) et a poursuivi sa formation pendant trois ans dans l’Ouest du Nigeria, à l’Hôpital du Collège universitaire d’Ibadan. Après avoir acquis une formation complémentaire en immunologie clinique en Grande-Bretagne, il est retourné au Nigeria (1970) pour aider à établir une nouvelle école de médecine à l’Université Ahmadu Bello, à Zaria. Il a poursuivi ses recherches sur le paludisme et les maladies à méningocoques dans cet établissement. Le Dr Greenwood a dirigé pendant 15 ans le UK Medical Research Council Laboratories en Gambie (1980-1995). Il a aidé à établir un programme de recherche multidisciplinaire axé sur les maladies infectieuses les plus répandues : le paludisme, la pneumonie, la rougeole, la méningite, l’hépatite et le VIH2. Il a démontré l’efficacité des moustiquaires de lit imprégnées d’insecticide dans la prévention des décès dus au paludisme chez les enfants, ainsi que l’impact des vaccins Haemophilus influenzae de type b et antipneumococciques conjugués en Afrique subsaharienne. En 1996, le Dr Greenwood a rejoint la London School of Hygiene and Tropical Medicine, où il est maintenant professeur Manson de médecine tropicale clinique. Il a dirigé le Gates Malaria Partnership (2001-2009) et, en 2008, est devenu directeur du Malaria Capacity Development Consortium, qui appuie les programmes de formation de lutte contre le paludisme dans cinq universités d’Afrique subsaharienne. Il est également directeur d’un consortium qui étudie l’épidémiologie de l’infection à méningocoques en Afrique avant l’introduction d’un nouveau vaccin conjugué.

Lorne A. Babiuk
OC SOM PHD DSC FRSC
Prix Canada Gairdner Wightman
2012
Pour son leadership national et international exceptionnel dans le développement de vaccins et la recherche sur la lutte aux maladies infectieuses humaines et animales
Vice-recteur à la recherche, Université de l’Alberta, Edmonton, AB
Le défi : Réduire le taux de décès et de maladie chez les humains et les animaux en mettant en place l’infrastructure physique et intellectuelle nécessaire pour créer de nouveaux vaccins qui s’attaquent aux maladies infectieuses. Le travail : Le Dr Babiuk a conjugué deux objectifs de recherche qui sont habituellement abordés séparément : les animaux et les humains. Il a identifié un vaccin contre la diarrhée causée par le rotavirus chez les veaux, qui a ensuite été développé en un vaccin pour les humains. Il a également été une force motrice dans la création du VIDO, un centre international de vaccins à Saskatoon. Pourquoi cela est important : Un tiers de tous les décès humains sont causés par les maladies infectieuses. Environ 70 % des nouvelles maladies qui sont apparues au cours des 30 dernières années ont été transmises des animaux aux humains. Celles-ci comprennent la maladie de la vache folle, le SRAS et la contamination de l’eau par la bactérie E. coli, à Walkerton, en Ontario. Lorne Babiuk a obtenu un doctorat (1972) de l’Université de la Colombie-Britannique. Il s’est joint à l’Université de l’Alberta à titre de vice-président (Recherche) en 2007. Avant d’accepter ce poste à l’Université de l’Alberta, il a passé 34 ans à l’Université de la Saskatchewan, où il a été responsable de la mise sur pied réussie des installations de recherche de VIDO (Vaccine and Infectious Disease Organisation). Sous la direction de Lorne Babiuk, VIDO est devenue internationalement reconnue comme chef de file du développement de nouveaux vaccins. Pendant son séjour à VIDO, Lorne Babiuk a complété un projet d’expansion de 19,4 millions $ (en 2005) et obtenu du financement pour InterVac, le laboratoire de confinement biologique de niveau 3 d’une valeur 140 millions $ qu’il a créé pour les travaux sur les maladies infectieuses (ouvert en septembre 2011). En plus d’être vice-président (Recherche) et ancien directeur de VIDO, Lorne Babiuk a publié plus de 100 essais et critiques et 500 manuscrits évalués par des pairs, principalement en virologie et en immunologie. Plus récemment, ses efforts ont porté sur la formulation et l’administration des vaccins. Il est membre de l’Infectious Disease Society of America, de la Société royale du Canada et de l’Académie européenne des sciences, ainsi qu’officier de l’Ordre du Canada.

Michael Rosbash
PHD
Prix internationaux Canada Gairdner
2012
Pour ses découvertes révolutionnaires concernant l’horloge biologique responsable des rythmes circadiens
Professeur de neurosciences Peter Gruber, Université Brandeis, Waltham, MA, et chercheur, Howard Hughes Medical Institute
Le défi : Comment notre horloge biologique interne guide-t-elle notre corps toute la journée? Le travail : Avec les Drs Jeffrey Hall et Michael Young, le Dr Rosbash a découvert que nos horloges circadiennes sont contrôlées par un petit groupe de gènes qui travaillent au niveau de la cellule individuelle. Des mutations subtiles dans l’un de ces gènes peuvent accélérer ou ralentir nos rythmes quotidiens. Pourquoi cela est important : Leurs découvertes au sujet de l’horloge biologique ont des applications pour les troubles du sommeil et de l’appétit. Elles ont également des applications pour des organes tels que le cerveau, le foie, les poumons et la peau, qui utilisent les mêmes mécanismes génétiques pour contrôler leurs activités rythmiques. Michael Rosbash, Ph.D., est chercheur au Howard Hughes Medical Institute et professeur de biologie à l’Université Brandeis, à Waltham, au Massachusetts. Michael Rosbash a contribué à révéler la base moléculaire des rythmes circadiens, l’horloge biologique intégrée qui régit le sommeil et l’éveil, l’activité et le repos, les niveaux d’hormones, la température du corps et d’autres fonctions. À l’aide de la mouche à fruit drosophile, il a identifié des gènes et des protéines impliquées dans la régulation de cette horloge et a proposé une théorie de son fonctionnement. Les découvertes de Michael Rosbash s’appliquent aux humains et à d’autres mammifères et pourraient éventuellement conduire à la mise au point de médicaments pour traiter l’insomnie, le décalage horaire et d’autres troubles du sommeil. Après son arrivée à l’Université Brandeis, Michael Rosbash s’est de plus en plus intéressé à l’influence des gènes sur le comportement. En 1974, il a commencé à travailler avec Jeffrey Hall et, en 1984, ils ont cloné le gène de l’horloge interne. Plusieurs années plus tard, ils ont proposé un mécanisme par lequel une horloge moléculaire de 24 heures pourrait fonctionner : une boucle de rétroaction négative transcriptionnelle. Leur modèle tient toujours, en dépit de la découverte de gènes supplémentaires du rythme circadien. En substance, les gènes qui font partie de cette boucle activent la production de protéines clés jusqu’à ce qu’une activité critique de chacune s’accumule et désactive la transcription.

Howard Cedar
MD PHD
Prix internationaux Canada Gairdner
2011
Pour ses découvertes pionnières sur la méthylation de l’ADN et son rôle dans l’expression génique
Département de biologie du développement et de recherche sur le cancer, Université hébraïque de Jérusalem, Jérusalem

Le défi : Comment les cellules savent-elles quels gènes utiliser et lesquels ignorer? Le travail : Howard Cedar – avec Aharon Razin et Adrian Bird – a démontré comment l’ajout d’un groupe chimique simple (un groupe méthyle) à l’ADN affecte le moment et la façon dont l’information génétique est utilisée. Pourquoi cela est important : Comprendre comment activer et désactiver la méthylation pourrait conduire à des traitements pour le cancer et d’autres maladies. Biographie Le professeur Howard Cedar est né à New York en 1943. Il a obtenu un B.Sc. en mathématiques du M.I.T. et a ensuite poursuivi des études de médecine et un doctorat en microbiologie sous la tutelle du Dr James Schwartz à l’Université de New York (N.Y.U.), recevant son diplôme en 1970.

Pour ses découvertes pionnières sur la méthylation de l’ADN et son rôle dans l’expression génique
Wellcome Trust Centre for Cell Biology, Université d’Édimbourg, Édimbourg
Le défi : Comment les cellules savent-elles quels gènes utiliser et lesquels ignorer? Le travail : Adrian Bird, Aharon Razin et Howard Cedar ont démontré comment l’ajout d’un groupe chimique simple (un groupe méthyle) à l’ADN affecte le moment et la façon dont l’information génétique est utilisée. Pourquoi cela est important : Comprendre comment activer et désactiver la méthylation pourrait conduire à des traitements pour le cancer et d’autres maladies. Adrian Bird est titulaire de la chaire Buchanan de génétique à l’Université d’Édimbourg et directeur du Wellcome Trust Centre for Cell Biology. Il est détenteur d’un doctorat de l’Université d’Édimbourg. Après avoir acquis une expérience postdoctorale dans les universités de Yale et de Zurich, il s’est joint au Mammalian Genome Unit du Medical Research Council à Édimbourg. En 1987, il est parti pour Vienne, où il est devenu chercheur principal à l’Institut de pathologie moléculaire, nouvellement fondé. Les recherches du Dr Bird portent sur la biologie fondamentale et la signification biomédicale de la méthylation de l’ADN. Son laboratoire a identifié des îlots CpG comme marqueurs de gènes dans le génome des vertébrés et a découvert des protéines qui lisent le signal de méthylation de l’ADN en vue d’influencer la structure de la chromatine. Des mutations dans l’une de ces protéines, MeCP2, provoquent le trouble du syndrome de Rett du spectre de l’autisme. Le laboratoire du Dr Bird a établi un modèle murin du syndrome de Rett et montré que le phénotype neurologique grave qui en résulte peut être guéri. Les prix qu’il a reçus comprennent le Prix Louis-Jeantet de médecine (1999) et le Prix Charles-Léopold Mayer de l’Académie française des sciences (2008). Il a été gouverneur du Wellcome Trust de 2000 à 2010 et est actuellement fiduciaire de Cancer Research UK.

2011
For his pioneering discoveries on DNA methylation and its role in gene expression.
Director, Wellcome Trust Centre for Cell Biology, University of Edinburgh, Edinburgh, UK

The challenge: How do cells know which genes to use and which to ignore?
The work: Bird – along with Aharon Razin and Howard Cedar – demonstrated how adding a simple chemical group (a methyl group) to DNA affects how and when genetic information is used.
Why it matters: Understanding how to turn methylation on and off could lead to treatments for cancer and other diseases.
Bio
Adrian Bird holds the Buchanan Chair of Genetics at the University of Edinburgh and is Director of the Wellcome Trust Centre for Cell Biology. He obtained his PhD at Edinburgh University. Following postdoctoral experience at the Universities of Yale and Zurich, he joined the Medical Research Council's Mammalian Genome Unit in Edinburgh. In 1987 he moved to Vienna to become a Senior Scientist at the newly-founded Institute for Molecular Pathology. Dr Bird's research focuses on the basic biology and biomedical significance of DNA methylation. His laboratory identified CpG islands as gene markers in the vertebrate genome and discovered proteins that read the DNA methylation signal to influence chromatin structure. Mutations in one of these proteins, MeCP2, cause the autism spectrum disorder Rett Syndrome. Dr Bird's laboratory established a mouse model of Rett Syndrome and showed that the resulting severe neurological phenotype can be cured. Awards include the Louis-Jeantet Prize for Medicine (1999) and the Charles-Léopold Mayer Prize of the French Academy of Sciences (2008). He was a governor of the Wellcome Trust from 2000 - 2010 and is currently a Trustee of Cancer Research UK.

Akira Endo
Prix internationaux Canada Gairdner
2017
Pour la découverte originale et le développement des statines, des inhibiteurs de la biosynthèse du cholestérol, qui ont transformé la prévention et le traitement des maladies cardiovasculaires
Président, Biopharm Research Laboratories, professeur émérite distingué, Université d’agriculture et de technologie de Tokyo, Tokyo, Japon
Les travaux Le Dr Endo a découvert le premier médicament de type statine, la compactine, et a démontré son efficacité clinique. Les statines sont une classe de médicaments aux propriétés hypocholestérolémiantes remarquables qui ont révolutionné la prévention et le traitement de la maladie coronarienne (MC). Elles abaissent la partie du cholestérol appelée « mauvais cholestérol », techniquement connue sous le nom de lipoprotéines de basse densité, ou cholestérol LDL. Le Dr Endo a étudié des milliers d’organismes, à la recherche de substances naturelles (produits) pouvant bloquer une enzyme clé dans la voie biochimique qui produit le cholestérol, un important facteur contribuant à la coronaropathie. C’est exactement ce que fait l’organisme qu’il a repéré, et son travail a incité la société Merck à lancer un programme de développement de médicaments qui a conduit, il y a plus de 20 ans, à la première statine approuvée pour usage médical. Cette avancée a permis à d’autres sociétés pharmaceutiques de s’engager dans la même voie. L’impact Les statines sont maintenant utilisées couramment pour prévenir et traiter la MC partout dans le monde. Bien que la MC soit aggravée par de multiples facteurs de risque, la réduction des niveaux de LDL a, en elle-même, un impact significatif. En découvrant les statines, le Dr Endo a inauguré une nouvelle ère dans la prévention et le traitement de la MC et l’on estime que des millions de personnes ont vu leur vie se prolonger grâce à un traitement à base de statine.

Akira Endo
Canada Gairdner International Award
2017
For the first discovery and development of statins, inhibitors of cholesterol biosynthesis that have transformed the prevention and treatment of cardiovascular disease.
President, Biopharm Research Laboratories; Distinguished Professor Emeritus, Tokyo University of Agriculture and Technology, Tokyo, Japan

The Work:
Dr. Endo discovered the first statin drug, compactin, and demonstrated its clinical efficacy. Statins are a class of drugs with remarkable cholesterol-lowering properties that have revolutionized the prevention and treatment of coronary heart disease (CHD). They lower the part of cholesterol known as “bad cholesterol”, technically known as low density lipoprotein or LDL cholesterol. Dr. Endo sifted through thousands of organisms, hunting for natural substances(products) that block a key enzyme in the biochemical pathway that produces cholesterol, a major contributor to CHD. The organism he found does exactly that and his work stimulated Merck to launch a drug-development program that led, 20+ years ago, to the first statin approved for medical use. This advance paved a path for other pharmaceutical companies to follow.

The Impact:
Statins are now routinely used to prevent and treat CHD throughout the world. Although CHD is aggravated by multiple risk factors, reducing LDL levels alone makes a significant impact. By discovering statins, Dr. Endo ushered in a new era in preventing and treating CHD and it is estimated that millions of people have extended their lives through statin therapy.

Antoine M Hakim
Canada Gairdner Wightman Award
2017
For outstanding research into strokes and their consequences and championing stroke prevention and treatment in Canada and beyond
Emeritus Professor, Neurology, University of Ottawa, Ottawa, ON, Canada

The Work:

Dr. Hakim is one of Canada’s most distinguished scientists who has earned a world-renowned reputation for his leadership in neuroscience research with an emphasis on stroke research. In the early 1980's Dr. Hakim characterized a penumbral region around a stroke’s ischemic core — brain tissue with enough energy to survive for a short time after blood loss and with the potential to regain normal function if blood flow was restored. Dr. Hakim, who joined the University of Ottawa in 1992, led the charge to set up the Canadian Stroke Network, a network of centres of excellence; he then partnered with the Heart and Stroke Foundation and other organizations to develop and apply a nation-wide Canadian Stroke Strategy. This work was critical to changing attitudes towards strokes, which went from being a devastating condition to one that is preventable, treatable and repairable.

The Impact:

In 2006, Dr. Hakim and colleagues published the first ‘Canadian Best Practice Recommendation for Stroke Care’ (updated in 2008, 2010 and 2012) and developed performance indicators and toolkits for healthcare providers to set up stroke units and improve emergency medical services. They also instituted a multi-layered national education program to enhance stroke prevention and the delivery of acute stroke care through the coordination of services and the implementation of best practices. Within five years of the Strategy’s implementation, Ontario alone saw referrals to stroke prevention clinics increase by 34% and stroke patient admissions decrease by 11%.

Cesar Victora
John Dirks Canada Gairdner Global Health Award
2017
For outstanding contributions to maternal and child health and nutrition in low and middle income countries, with particular focus on the impact of exclusive breastfeeding on infant mortality and on the long-term impact of early-life nutrition.
Emeritus Professor, Federal University of Pelotas, Pelotas, Brazil

The work:

Dr. Victora’s career has focused on the factors affecting maternal and child health in low- and middle income countries. He has concentrated in the three main areas of child health and nutrition, health program monitoring and evaluation, and health equity. Returning to Brazil after his doctorate, he helped set up one of the longest running birth cohort studies in the world, the 1982 Pelotas Birth Cohort, in which 6,000 individuals are being followed up to the present time. His studies helped establish the influence of the first 1,000 days (from conception until the age of two years) on lifelong outcomes, including chronic diseases and human capital.

The Impact:

Possibly, Dr. Victora’s greatest contribution to Public Health was his work in the 1980s with the first study showing the importance of exclusive breastfeeding for preventing infant mortality. His findings contributed to global policy recommendations by UNICEF and the World Health Organization for mothers to breastfeed their infants exclusively for the first six months of life. More recently, his long-term birth cohorts documented the benefits of breastfeeding for adult intelligence, education and income, as well as the long-term consequences of early-life undernutrition. Dr. Victora also made important contributions on how to evaluate the impact of health programs on child mortality and on the study of social inequalities in child health.

Rino Rappuoli
Canada Gairdner International Award
2017
For pioneering the genomic approach, known as reverse vaccinology, used to develop a vaccine against meningococcus B which has saved many lives worldwide.
Chief Scientist and Head External R&D, GSK Vaccines, Siena, Italy

The work:
Dr. Rappuoli is a pioneer in the world of vaccines and has introduced several novel scientific concepts. First, he introduced the concept that bacterial toxins can be detoxified by manipulation of their genes (genetic detoxification, 1987). Next, the concept that microbes are better studied in the context of the cells they interact with (cellular microbiology, 1996), and then the use of genomes to develop new vaccines (reverse vaccinology, 2000). In the process of reverse vaccinology the entire genomic sequence of a pathogen is screened using bioinformatics tools to help determine which genes code for which proteins, against which vaccines can be developed.

The impact:
Dr. Rappuoli also worked on several molecules which became part of licensed vaccines. He characterized a molecule, CRM197, that today is the most widely used carrier for vaccines against Haemophilus influenzae, meningococcus and pneumococcus. Later he developed a vaccine against pertussis containing genetically detoxified pertussis toxin and the first conjugate vaccine against meningococcus C that eliminated the disease in the United Kingdom in 2000. His work on reverse vaccinology led to the licensure of the first meningococcus B vaccine approved in Europe and Canada in 2013 and USA in 2015.

Lewis E Kay
Canada Gairdner International Award
2017
For the development of modern NMR spectroscopy for studies of biomolecular structure dynamics and function, including applications to molecular machines and rare protein conformations
Professor, Departments of Molecular Genetics, Biochemistry and Chemistry, University of Toronto; Senior Scientist, Hospital for Sick Children, Toronto, ON, Canada

The Work:
Professor Kay and his coworkers have made important contributions to the field of biomolecular nuclear magnetic resonance (NMR) spectroscopy, with the development of methods that are used to ‘visualize’ protein molecules in their natural solution environment and to obtain information about how their shapes evolve in time, leading to biological function. These methods have shed light on how molecules involved in neurodegeneration can form abnormal structures that ultimately lead to diseased states. In addition, his work has extended our understanding of how cellular machines function and how the communication between different parts of these machines can be targeted for the development of drugs in the fight against certain cancers.

The Impact:
His research has expanded our understanding of the flexible nature of protein structure and the importance of flexibility to both function and malfunction. This, in turn, has led to new insights into what the key regions of molecules might be for drug targeting. The methods developed by Dr. Kay are used in labs around the world, including those researching illnesses such as diabetes, cancer and cardiovascular disease. The tools developed by his research group are disseminated freely and are extensively used worldwide.

Huda Y Zoghbi
Canada Gairdner International Award
2017
For the discovery of the genetic basis of Rett syndrome and its implications for autism spectrum disorders
Professor, Baylor College of Medicine; Investigator, Howard Hughes Medical Institute; Director, Jan and Dan Duncan Neurological Research Institute, Texas Children’s Hospital, Houston, TX, USA

The Work:
Trained as a child neurologist, Zoghbi could not bear the plight of children affected by devastating neurological diseases so she pursued research in hope of helping her patients. After encounters with patients with Rett syndrome—a disorder that strikes after a year of normal development and presents with developmental regression, social withdrawal, loss of hand use and compulsive wringing of the hands, seizures and a variety of neurobehavioral symptoms—she decided to find its genetic roots. The biggest challenge was that Rett syndrome is typically a sporadic disorder (one in a family) and the genome was neither mapped nor sequenced. Zoghbi’s perseverance paid off when after a 16-year search she discovered that Rett syndrome is caused by mutations in MECP2. Zoghbi revealed the importance of MeCP2 for the function of various neuronal subtypes and pinpointed the contributions of various neuronal subtypes in the brain to various neuropsychiatric features. Zoghbi also provided evidence that the brain is exquisitely sensitive to the levels of MeCP2 and that doubling MeCP2 levels causes progressive neurological deficits in mice. This disorder is now recognized as MECP2 Duplication Syndrome in humans. Her recent work showed the symptoms of adult mice modeling the duplication disorder can be reversed using antisense oligonucleotides that normalize MeCP2 levels.

The Impact:
The discovery of the Rett syndrome gene provided a straightforward diagnostic genetic test allowing early and accurate diagnosis of the syndrome. It also revealed that mutations in MECP2 can also cause a host of other neuropsychiatric features ranging from autism to juvenile onset schizophrenia. Further, it provided evidence that an autism spectrum disorder (ASD) or an intellectual disability disorder (IDDs) can be genetic even if it is sporadic (not inherited). Today we know that dozens of ASDs and IDDs are caused by sporadic new mutations. Moreover, her discovery opened up a new area of research on the role of epigenetics in neuropsychiatric phenotypes. Her use of an antisense oligonucleotide to lower MeCP2 levels provides a potential therapeutic strategy for the MECP2 duplication syndrome and inspires similar studies for other duplication disorders.

David Julius
Canada Gairdner International Award
2017
For determining the molecular basis of somatosensation- how we sense heat, cold and pain.
Professor & Chair, Department of Physiology; Morris Herzstein Chair in Molecular Biology and Medicine, University of California San Francisco, San Francisco, CA, USA

The Work:

Dr. Julius has used distinctive molecules from the natural world – including toxins from tarantulas and coral snakes, and capsaicin, the molecule that produces the “heat” in chili peppers – to understand how signals responsible for temperature and pain sensation are transmitted by neural circuits to the brain.

In his research Dr. Julius has homed in on a class of proteins called TRP (pronounced “trip”) ion channels to discover how the chemical compound responsible for the spicy heat of chili peppers – called capsaicin – elicits a burning sensation when eaten or touched. The research led to the identification and cloning of the specific protein responsible, named TRPV1. On the flip side, Dr. Julius has used menthol, a natural cooling agent, to identify a receptor for “real” cold. This protein, named TRPM8, is a close molecular cousin of TRPV1, pointing to a common mechanism for sensing temperature. As in the case of TRPV1, this ion channel contributes to hypersensitivity to cold, such as that experienced after chemotherapy or other types of nerve injury.

The Impact:

Somatosensation, our sense of touch and pain, serves as a warning system to guard us against injury. While critical to our survival and well-being, this system can become hypersensitive, resulting in chronic pain. This work helps to explain how such positive and negative aspects of pain sensation arise – insight that is critical to understanding the genesis of chronic pain syndromes. One indication of the importance of this work to medicine is the interest in TRP channels as potential targets for a new generation of painkillers.

Seymour Benzer
BA MS PHD
Canada Gairdner International Award
2004, 1964
2004 For pioneering discoveries that both founded and greatly advanced an entire field of neurogenetics, thereby transforming our understanding of the brain and its mechanisms. 1964 In recognition of his outstanding contributions to the knowledge of genetics and molecular biology, and in particular for his elucidation of the fine structure of genes, which has made it possible to extend the limits of genetic resolution by relating genetic changes to chemical alterations in deoxyribonucleic acid, thus clarifying the chemical bases of heredity in determining the nature and properties of cells and viruses.
Emeritus Professor, California Institute of Technology, Pasadena, CA, USA; Lafayette, IN, USA

Dr. Benzer's work in the 1950's, which was recognized by a Gairdner Award in 1964, achieved the fine-structure mapping of a gene, thereby laying the foundations of molecular genetics. His later studies, recognized by the 2004 Gairdner Award, tackled the problem of the inheritance of behavior, using gene mutations to dissect the underlying events in the nervous system of the fruit fly, Drosophila. His work led to the discovery of specific genes that participate in various behavioral phenomena, including genes such as per, which controls the biological clock, dunce, which is needed for learning, and other genes, shown to be important for sexual courtship, vision, or prevention of neurodegeneration. At age 82, Benzer continues to do pioneering research that focuses on the problem of aging, with Drosophila as a model organism.

Dr. Seymour Benzer is the Boswell Professor of Neuroscience, Emeritus (Active) at the California Institute of Technology (Caltech), in Pasadena, California. Benzer grew up in Brooklyn, New York, and majored in physics at Brooklyn College. Graduating in 1942, he continued his studies at the Purdue University, Lafayette, Indiana, where he participated in the war effort to develop semiconductor devices for detecting radar microwaves. On receiving his PhD in 1947, he was appointed to the faculty at Purdue, but, inspired by reading Schrodinger's book "What is Life", soon requested leave of absence to study genes, spending two years with Max Delbruck at Caltech and a year at the Pasteur Institute with Jacob, Monod, and Lwoff. Benzer moved his laboratory from Purdue University to Caltech in 1965. He received The Lasker Award in 1971, International Academy of Sciences in 1975 and 2001 and the Wolf Prize for Medicine in 1991.

MD DSC
Canada Gairdner International Award
1996
For establishing the critical importance of chromosomal rearrangement as a specific cause of human cancer and for a lifetime of research to identify the genes that are rearranged to cause leukemia and lymphoma.
Chicago, IL, USA

Janet Davidson Rowley was born in New York City. She received her BS, PhD and MD degrees from the University of Chicago. Her interest in cytogenetics was sparked by her work as a Research Fellow in a clinic for retarded children at Cook County Hospital, Chicago, in the early days of human cytogenetics, and led to postdoctoral research at Oxford University in 1961-62 and again in 1970-71. She developed her academic career at the University of Chicago where she became a full Professor in 1978 even though she worked only three days a week while her children were young. She received certification by the American Board of Medical Genetics in 1982 and was awarded the Blum-Riese Distinquished Service Professorship in 1984.

Dr. Rowley has virtually single-handedly changed the view of the hematology/oncology community and of the cancer biology community regarding the critical importance of recurring chromosome abnormalities in leukemia and lymphoma. She has provided some of the most persuasive evidence that tumours are associated with specific cytogenetic changes which reflect critical genetic changes.

Robert S. Langer
SCD
Canada Gairdner International Award
1996
For discoveries that led to the development of controlled drug release systems.
Cambridge, MA, USA

Dr. Langer is the Kenneth J. Germeshausen Professor of Chemical and Biomedical Engineering at the Massachusetts Institute of Technology. The strength of his curriculum vitae is best illustrated by the fact that he has been elected to membership in all three academies - Institute of Medicine of the National Academy of Sciences, National Academy of Engineering and National Academy of Science.

There is general agreement that Dr. Langer pioneered the field of controlled drug release delivery systems (slow release oral systems, transdermal patches, injectable microspheres, and slow release implants). These delivery systems involve macromolecules that have been incorporated into solid polymers from which they are released at controlled rates. This development has revolutionized medical therapy, permitted new therapies for patients, and by reducing the dose administered, has avoided complications and reduced costs. Examples of current drug applications include nitroglycerin, nicotine, cancer chemotheraputics, hormones and vaccines. In subsequent work, he determined the mechanism of release of drugs from polymers and then identified the factors that could be used to control the rate of release.

Canada Gairdner International Award
1996

For the discovery of the role of Helicobacter Pylori as a cause of peptic ulcer disease and the benefit that patients receive from its eradication.
Charlottesville, VA, USA

Dr. Marshall was born in Kagoorlie, Western Australia, and educated in Perth. He graduated in Medicine from the University of Western Australia in 1974. After completion of his postgraduate training, he became a fellow of the Royal Australian College of Physicians (FRACP) in 1983, and held positions in General Medicxine, Microbiology, and Gastroenterology at the Royal Perth Hospital until 1986. In 1986 he joined the Division of Gastroenterology, Faculty of Medicine, University of Virginia, in Charlottesville, VA, where he is currently Clincal Associate Professor. He is also the founder and President of the Helicobacter Foundation in Charlottesville.

When he was a medical resident in 1981, Dr. Marshall and pathologist Dr. Robin Warren noticed that spiral bacteria, though not recognized as common occupants of the human gastric mucosia, were present in over half the patients attending for upper GI endoscopy. In 1982 Dr. Marshall was the chief investigator in a study that established the significance of the new bacterium in gastric ulcer and doudenal ulcer. The organism was isolated and given the name Helicobacter Pylori. Later, initially through experiments with himself as a subject, Dr. Marshall established that gastritis associated with hypochlorhydria is symptomatic of acute H. Pylori infection. Dr. Marshall was the first to appreciate the need for drugs with an antibacterial effect rather than acid-reducing drugs, to reduce the relapse rate in duodenal ulcers.

James E. Rothman

Canada Gairdner International Award

Array
For the identification of proteins involved in intracellular traffic and vesicle fusion.
New York, NY, USA

Dr. James E. Rothman is the Chairman of the Cellular Biochemistry aand Biophysics Program of the Rockefeller Research Laboratory at the Memorial Sloan-Kettering Cancer Center in New York. He obtained his BA at Yale University, his PhD at Harvard University under Eugene Kennedy, did a post-doctoral stage in the laboratory of Dr. H. Lodish at MIT, and immediately landed a position in the Department of Biochemistry at Stanford University. After advancing to the rank of Professor in that institution, he became a Squibb Professor of Molecular Biology at Princeton University, and in 1991 became Chairman of the Program in Cellular Biochemistry of the Sloan-Kettering Institute. He is currently also the Vice-Chairman of that Institution.

Dr. Rothman was the first one to develop in vitro assays to reproduce the intricate intracellular movement, targeting and delivery of goods among organelles. These in vitro reconstitution assays continue to be the gold standard in the description of novel intracellular pathways. In addition, together with Dr. Gunter Blobel, Dr. Rothman has made major advances in the discovery of the recognition of the signal peptide of proteins during translation.

Together with Dr. Randy Schekman from Berkley University, James Rothman developed and exploited the isolation and analysis of mutants of yeast which are defective in intracellular protein transport, and expanded these discoveries to the identification and cloning of the proteins that constitute the ubiquitous machinery of membrane docking and fusion.

For the identification of proteins involved in intracellular traffic and vesicle fusion.
Berkeley, CA, USA

Dr. Schekman is Professor and Chair of the Department of Molecular and Cell Biology and Investigator, Howard Hughes Medical Institute, University of California, Berkley. Schekman received his BA in Molecular Biology at UCLA, his PhD in Biochemistry, studying with Arthur Kornberg at Stanford University and he conducted postdoctoral work with S.J. Singer at UCSD. Schekman joined the Berkley facility in 1976.

At Berkley, Schekman initiated studies on the mechanism of protein secretion using the model eukaryotic cell, S. cerevisiae. A classic genetic approach was developed to illuminate the processes of polpeptide import into the endoplasmic reticulum, protein sorting, and packaging into transport vesicles to acceptor membrane compartments. SEC genes that encode the proteins implicated in these processes were cloned and shown to be evolutionary conserved. Mammalian orthologs of the yeast SEC genes are now known to define most aspects of normal and specialized secretory processes. Schekman's group developed complementary biochemical approaches to define the exact roles of SEC proteins. Novel insights included the discovery of the major subunit of the polypeptide translocation channel of the ER (sec61p), the demonstration that cytosolic hsp70 promotes the post-translational translocation of secretory and mitochondrial precursor polypeptide, and the isolation of a novel coat protein complex, COPII, responsible for secretory and membrane cargo sorting and anterograde vesicle budding from the ER.

In recognition of their pioneering contribution to our understanding of apoptosis.
Professor of Biology, Massachusetts Institute of Technology, Cambridge, MA, USA

Dr. Horvitz obtained SB degrees in Mathematics and Economics from MIT in 1968 and his PhD from Harvard University in 1974. During his post-doctoral fellowship with Dr. Sydney Brenner, (Gairdner Awardee 1978, 1991), Dr. Horvitz began using the nematode Caenorhabditis elegans as a simple model system to study development. In 1986, Dr. Horvitz described the genetic basis of programmed cell death in the development of this organism. He discovered many of the regulatory genes controlling apoptosis and showed that similiar genes exist in humans. Horvitz's work definitively showed that apoptosis was a genetically regulated mechanism and has subsequently led to the discovery of countless novel death signalling pathways whose dysregulation directly contributes to human disease. He has consistently published in high-quality journals and has served on many editorial boards, visiting committees and advisory committees. He has received numerous awards for his accomplishments, including the General Motors Cancer Research Foundation, Alfred P. Sloan Jr. Prize in 1998. He is a member of the U.S. National Academy of Sciences as well as a Fellow of the American Academy of Arts and Sciences and the American Academy of Microbiology.

Canada Gairdner International Award
2000
For their discovery of the molecular and cellular basis of antigen processing leading to our understanding of the physiological role of histocompatibility molecules and T lymphocyte antigen recognition.
Professor, Institute of Molecular Medicine, Oxford University, Oxford, UK

Alain Townsend is honored for seminal contributions to the understanding of T-cell activation and its regulation. He observed that T cells can recognize portions of a pathogen that are not expressed on its surface. This gave rise to experiments demonstrating that viral pathogens are degraded inside antigen presenting cells, and ultimately pieces of the virus derived from its core associate with Class I products of the Major Histocompatibility Complex (MHC). Subsequently Dr. Townsend established the essential role of these components in the assembly and surface expression of MHC Class I molecules themselves, leading to the discovery of peptide transporters in the endoplasmic reticulum. These fundamental contributions established the integral role that pathogens play in regulating immune system function, and a new paradigm of MHC gene expression and function relevant to the rational understanding of infectious and autoimmune diseases.

Dr. Townsend is a medical graduate of St. Mary's Hospital, London (1977) where he first developed his interest in human diseases associated with alleles of the MHC complex. He then began graduate study in immunology at the National Institute for Medical Research, Mill Hill, London. In 1984 he joined the Institute of Molecular Medicine, Oxford, and in 1992 became Ad Hominem Professor of Molecular Immunology. Recently he has undertaken further clinical training at the John Radcliffe Hospital where he is an Honorary Consultant in General Internal Medicine. Among other honors he is a Fellow of the Royal Society and an International Research Scholar of the Howard Hughes Medical Institute. His honors include the William B. Coley Award, the Cheadle Medal and Prize for Clinical Medicine and the Louis Jeantet Prize for Medicine.

2000
For their discovery of the molecular and cellular basis of antigen processing leading to our understanding of the physiological role of histocompatibility molecules and T lymphocyte antigen recognition.
Mallinckrodt Professor, Department of Pathology, Washington University, St. Louis, MO, USA

Emil Unanue is honored for his seminal contributions to the understanding of T-cell activation and its regulation. He showed that T-cells do not recognize intact pathogens but rather, recognize small components of the pathogen presented in the context of Class II products of the Major Histocompatibility Complex (MHC). These components are generated and presented in association with MHC Class II molecules by antigen-presenting cells. The discovery of the molecular and cellular basis of this process has provided a new interpretation of how the cells of the immune system recognize pathogens, and has opened up novel approaches to a rational analysis of the pathobiology of infectious and autoimmune diseases.

Dr. Unanue graduated in medicine in 1960 from the University of Havana, Cuba. He trained from 1961 to 1970 in Pittsburgh and La Jolla in the United States and at the National Institute for Medical Research, Mill Hill, London. In 1985 he joined Harvard University Medical School, where he became Mallinckrodt Professor of Immunopathology. In 1985 he moved to Washington University, St Louis, where he is Mallinckrodt Professor and Chairman of the Department of Pathology and Pathologist-in-Chief of the Barnes Jewish Hospital. Dr. Unanue's long record of distinctions includes the Albert Lasker Basic Medical Research Award and Membership in the Institute of Medicine of the National Academy of Sciences. He has also made distinguished contributions as a speaker, author, editor and member of scientific organizations and has been Chair of the National Academy of Sciences Section of Microbiology and Immunology.

Canada Gairdner International Award
2000
In recognition of his pioneering contributions to our understanding of the diagnosis, prevention and treatment of thromboembolic disorders.
Emeritus Professor, School of Medicine, McMaster University, Hamilton, ON, Canada

Jack Hirsh is a medical scientist equally at home in the laboratory and the clinical setting. His many distinguished contributions to the field of thromboembolism, which combine basic research, patient management and clinical trials, underlie the therapy of thromboembolism worldwide. His original observation in 1972 of the relationship between the in vitro anticoagulant activity of heparin and its efficacy in patients with venous thrombosis found immediate and widespread clinical application. His subsequent demonstration, with his colleagues, of the superior clinical efficacy of low-molecular-weight heparin revolutionized anti-thrombotic treatment, allowing management on an outpatient basis. His work on oral anticoagulants led to the development of the International Normalized Ratio, an advance in laboratory diagnosis and to clinical trials that assessed the efficacy and risk: benefit ratio of anticoagulants in a variety of clinical situations. Dr. Hirsh and his colleagues also established the value of aspirin in the prevention of stroke. These different but related observations have changed the clinical management of thromboembolism and have had a significant effect on patients' lives.

Born in Australia, Dr. Hirsh is a graduate of the University of Melbourne Medical School. He expanded his background in hematology at Washington University, St. Louis, the London Postgraduate Medical School and the University of Toronto. In 1973 he joined the Faculty of Medicine of McMaster University, Hamilton, where he is now Professor Emeritus of Medicine and is Director, Hamilton Civic Hospital Research Centre. He has received numerous honors including the Trillium Award of Ontario, the Order of Canada and election to the Canadian Medical Hall of Fame.

Clay Armstrong
MD PHD
Canada Gairdner International Award
2001
For the elucidation of the mechanism of action and molecular structure of cation channels.
Professor, School of Medicine, University of Pennsylvania, Philadelphia, PA, USA

Much of our present knowledge concerning ion channel structure and function can be traced to Dr. Clay Armstrong. He provided the first general description of the K+ channel pore, including the fundamental ideas of a selectivity filter, a wider inner vestibule and a gate on the inside. A consistent feature of Armstrong's contributions is the absolutely quantitative nature of the work and the resulting fidelity of his clear and concise descriptions. His work has been so profound that it has had enormous influence on the work of others, leading to our present understanding of channel structure and function. Armstrong's seminal work is of enormous value to human disease, the relief of human suffering and the broader aspects of medicine because of subsequent development of drug therapies that work through channels.

Clay Armstrong received his BA degree from Rice University in 1956 and his MD degree from Washington University, St. Louis in 1960. He was a postdoctoral fellow with Dr. K.S. Cole at the NIH from 1961-1964 and with Dr. A.F. Huxley, University College, London from 1964-1966. He has held professorial appointments at Duke University, the University of Rochester and the University of Pennsylvania School of Medicine, where he has been Professor of Physiology since 1976. Among his many honours are election to the National Academy of Sciences, 1987; Columbia University Louisa Gross Horwitz Prize for Biology or Biochemistry (shared with Bertil Hille) 1996; The Albert Lasker Basic Medical Research Award (shared with Bertil Hille and Rod MacKinnon) 1999.

Bertil Hille
PHD
Canada Gairdner International Award
2001
For the elucidation of the mechanism of action and molecular structure of cation channels.
Professor, Department of Physiology & Biophysics, School of Medicine, University of Washington, Seattle, WA, USA

Dr. Bertil Hille has provided medical science with a foundation for modern understanding of ion channels; his findings being as important for cardiac muscle as for the brain. His work has had enormous influence on the work of others, in no small part because his book on ion channels is widely read, being readily understood by novices in the field. Clinical medicine owes the concept of use-dependant block of ion channels by local anesthetics to Hille. He discovered the way that muscarinic acetycholine receptors in the heart, acting through G-proteins, turn on M-type Ca2+channels. He dissected the mechanism for modulation of K+ and N-type Ca2+ channels in sympathetic neurons. These contributions are all relevant to the development of drug therapies that work through channels. Thus Hille's seminal work is of enormous value to human disease and relief of human suffering and to the broader aspects of medicine.

Bertil Hille received his BS degree from Yale University in 1962 and his PhD from Rockefeller University in 1967. He was a postdoctoral fellow with Dr. A.L. Hodgkin at the Physiological Laboratories, Cambridge University from 1967-1968. He has been Assistant, Associate and Full Professor in the Department of Physiology and Biophysics, University of Washington School of Medicine, Seattle, since 1968. Among his many honours are: election to the National Academy of Sciences, 1986; Harvey Lecturer, New York, 1986; the Bristol Myers Squibb Award for distinquished Achievement in Neuroscience Research, 1990; Columbia University Louisa Gross Horwitz Prize for Biology or Biochemistry (shared with Clay Armstrong) 1996; The Albert Lasker Basic Medical Research Award (shared with Clay Armstrong and Rod MacKinnon) 1999.

Professor, Molecular Neurobiology & Biophysics, Rockefeller University, New York, NY, USA

Dr. Roderick MacKinnon's crystal structure of a K+ channel is the end point of a half-century of analysis of cation channel structure-function relationships. It is a stunning accomplishment that solidifies all of the work on the structure of the pore. MacKinnon has driven his field forward with an exceptional focus and intensity. His early work on the pore focussed attention on this critical region; his later work on the crystal structure has opened the field to other investigators who now have a firm basis for further molecular analysis. His work explains at the molecular level, exactly how drugs and toxins alter the properties of channels. His contributions, which are relevant to the development of drug therapies that work through channels. are of enormous value to human disease and relief of human suffering and to the broader aspects of medicine.

Roderick MacKinnon received his BA degree from Brandeis University in 1978 and his MD from Tufts University in 1982. He was a postdoctoral fellow with Dr. R. Morgan at Beth Israel Hospital, Harvard University from 1985-1986 and with Dr. C. Miller at Brandeis University from 1986-1989. He was Assistant, Associate and Full Professor in the Department of Neurobiology, Harvard Medical School from 1989-1996 and since 1996; he has been Professor of Molecular Neurobiology and Biophysics at Rockefeller University. Among his many honours are: election to the National Academy of Sciences, 2000; The Albert Lasker Basic Medical Research Award (shared with Clay Armstrong and Bertil Hille) 1999; and the Lewis S.

He has played a major role in the Human Genome Project, both personally and through the Sanger Centre, which he founded in 1993 for the mapping and sequencing of the human and other genomes and served as Director from 1992-2000.

Dr. Sulston has spent virtually his entire career at the University of Cambridge. He earned a BA in organic chemistry and a PhD, spent three years as a postdoctoral fellow at the Salk Institute and then returned to Cambridge as a member of the Laboratory of Molecular Biology. He has received numerous honors and in 2001 was knighted in the New Year's Honour list.

R. John Ellis
PHD
Canada Gairdner International Award
2004
For his fundamental discoveries concerning chaperone assisted protein folding in the cell and its relevance to neurodegeneration.
Emeritus Professor, Department of Biological Sciences, University of Warwick, Coventry, UK

John Ellis was a leader in the field of chloroplast biogenesis. He studied the biochemistry of the development of chloroplasts in higher plants. In 1980 Ellis discovered the first molecular chaperone. He found that in chloroplasts unassembled subunits of the rubisco complex were associated with another protein which turned out to be a chaperone. These seminal experiments foreshadowed the discoveries of Horwich and Hartl. Ellis subsequently made substantial contributions to the concept of molecular chaperones which are required to assist a variety of cellular processes in all types of cells.

Dr. Ellis earned his doctorate in 1960 from King's College, London for research on transamination reactions with Professor Davies. Postdoctoral studies were done at Oxford in the Biochemistry Department on sulfate reduction in bacteria with Professor Pasternak. In 1964 Dr. Ellis joined the Departments of Botany and Biochemistry at the University of Aberdeen. He moved to the newly founded Department of Biological Sciences at the University of Warwick in 1970 as Senior Lecturer and Head of the Chloroplast Research Group. In 1976 was awarded a Personal Chair in the department and in 1983 was elected to the Royal Society.

F. Ulrich Hartl
MD PHD
Canada Gairdner International Award
2004
For his fundamental discoveries concerning chaperone assisted protein folding in the cell and its relevance to neurodegeneration.
Director, Max-Planck Institute for Biochemistry, Martinsried, Germany

F. Ulrich Hartl's research is in mechanisms of cellular protein folding, specifically the structure and function of molecular chaperones. He delineated, resolved and reconstituted the complete pathway by which molecular chaperones cooperate to fold proteins in the living cell. In a series of elegant studies he established how the folding protein is recognized by one chaperone, thereby preventing premature misfolding, and then transferred to a molecular machine which promotes proper folding. While initially highly controversial, this mechanism is now well accepted and confirmed by x-ray crystallography. When these protein folding pathways are saturated or non-functional, protein aggregates accumulate in the cell. Examples of diseases that are likely the result of such aggregates are Alzheimer's and Huntington's Diseases.

Dr. Hartl earned his medical degree from the University of Heidelberg in 1990. He began his postdoctoral fellowship in organelle biogenesis at the Institute of Physiological Chemistry at the University of Munich and continued his studies in protein secretion at the University of California at Los Angeles. From 1993 to 1997, Dr. Hartl was an Associate Professor of Cell Biology and Genetics at Cornell University School of Medical Sciences. He received the Howard Hughes Award in 1994 and was an Associate Investigator for the Howard Hughes Medical Institute. In 1995 he was appointed to the William E. Snee Chair of Cellular Biochemistry at Memorial Sloan-Kettering Cancer Center. Dr. Hartl was appointed managing Director of the Max-Planck-Institut fur Biochemie, Germany in 1997.

2004
For his fundamental discoveries concerning chaperone assisted protein folding in the cell and its relevance to neurodegeneration.
Professor, Yale School of Medicine, New Haven, CT, USA

Arthur Horwich is a pioneer in the field of molecular chaperones. These are a special class of proteins that assist other proteins in folding into their final form, which determines their function. Horwich discovered an accessory protein that is required for folding of proteins imported into mitochondria. He then led the way in understanding the cavity-based chaperonins GroEL/GroES. His discoveries have advanced the understanding of protein folding and have profound implications for diseases, such as Alzheimer's, that are thought to result from protein misfolding.

Arthur Horwich received AB and MD from Brown University in 1973, trained in clinical pediatrics at Yale, and then pursued postdoctoral fellowship training first at the Salk Institute in the Tumor Virology Laboratory with Walter Eckhart and then at Yale in Medical Genetics with Leon Rosenberg. Dr. Horwich is a recipient of the 2001 Hans Neurath Award. He is a member of the National Academy of Sciences.

Douglas Coleman
PHD
Canada Gairdner International Award
2005
For contributions to our understanding of obesity and particularly for the discovery of the adipose tissue hormone, leptin.
Professor, The Jackson Laboratories, Bar Harbor, ME, USA

The incidence of obesity is reaching epidemic proportions in developed countries. Importantly, Douglas Coleman is a pioneer in the field of obesity. His innovative studies in mouse genetic models of obesity in the early 1970s provided compelling evidence for the existence of a hormone system that participated in the control of fat cell homeostasis. His research was the first to hint that the "dumb" fat cell participates in regulating the integrative biology of metabolism and weight control. Using elegant parabiosis cross-circulation protocols he noted that deficiency of a circulating "satiety" factor, or resistance to a circulating "satiety" factor, explained the phenotype of the obese (ob) and diabetes (db) mice, respectively. He concluded that the circulating factor would be fat cell-derived. The ob and db mice are now known to carry mutations in the leptin ligand and leptin receptor, respectively. These seminal findings, performed using integrative physiologic approaches, provided breakthrough insights into the causes of obesity.

Douglas Coleman was born and raised in Stratford, Ontario, Canada, and received his BSc degree from McMaster University in 1954. He completed his PhD at the University of Wisconsin in Biochemistry in 1958. His full career has been spent at the Jackson Laboratory in Bar Harbour, Maine, where he performed his classic parabiosis studies. Douglas Coleman is a recipient of numerous prestigious awards and accolades including the Claude Bernard Medal (1977) and membership in the National Academy of Sciences (1998).

For more than 50 years, the name of Professor Brenda Milner has been synonymous with memory. In the early 1950s, in collaboration with Dr.Wilder Penfield at the Montreal Neurological Institute/McGill University, she made various seminal contributions on the key role of the hippocampus and temporal lobes in recent memory events. The origins of modern cognitive neuroscience of memory can be traced directly to her rigorous and imaginative studies. She continues to pursue her research activities using modern brain imaging to dissect even further key components and regions functionally involved in cognitive processes. Her research has paved the way to molecularly-oriented approaches aimed at deciphering key genomic and cellular steps leading to memory traces.

Brenda Milner earned her BA (1939) in Experimental Psychology and her ScD (1972) from the University of Cambridge, and her PhD from McGill University in 1952 for research on intellectual effects of temporal-lobe damage in man with Professor D.O. Hebb. Since her service at the Universite de Montreal as Professeur agrege at the Institut de psychologie (1944-1952), she has been associated with McGill University, where she first became Research Associate in the Psychology Department in 1952. She has received a large number of national and international awards including 19 honorary degrees, fellowships in the Royal Society of Canada (1975) and of London (1979), the Foreign Associate title at the National Academy of Sciences - USA (1976), Officers of the Order of Canada (1984) and of Quebec (1985), first recipient of the Wilder Penfield Prize for Biomedical Research (Quebec, 1993), member of the Canadian Medical Hall of Fame (1997), Golden Jubilee Medal of Her Majesty Queen Elizabeth II (2002) and the National Academy of Sciences Award in the Neurosciences, USA (2004) and, the most recent, Companion of the Order of Canada (2005)

For pioneering research in the understanding of human memory, and providing the necessary framework within which findings in neuroanatomy, neuroplysiology, and neuropharmacology can be integrated.
Scientist Emeritus, Rotman Research Institute, Baycrest Hospital, Toronto, ON, Canada

Endel Tulving has clarified the nature of human memory at the behavioural level and made substantial additions to our knowledge of its neural correlates. His theorizing is of unusual breadth and coherence, has dealt with the relations between memory and consciousness at the experimental level, with the measurement of memory organization at the behavioural level, with methods for distinguishing memory systems at the experimental level, and with the neuroanatomical correlates of memory systems and processes at the level of brain mechanisms. In an incredibly productive career spanning nearly half a century, he has radically changed how scientists view human memory, and his theoretical frameworks now guide the whole field of memory research.

Dr. Tulving was born in Estonia, moving to Canada as a young adult. He earned his doctorate from Harvard University in 1957 and accepted a position at the University of Toronto. He remained in Toronto (except for a brief period at Yale University), serving as Chair of the Department of Psychology from 1974 to 1980, and becoming University Professor in 1985. He joined The Rotman Research Institute of Baycrest Centre in 1992 as the Tanenbaum Chair and is also the Clark Way Harrison Distinguished Visiting Professor of Psychology and Cognitive Neuroscience, Washington University in St. Louis. He is a member of seven distinguished societies: Fellow, Royal Society of Canada; Foreign Member, Royal Swedish Academy of Sciences; Fellow, Royal Society of London; Foreign Honorary Member, American Academy of Arts and Sciences; Foreign Associate, National Academy of Sciences, U.S.A; Foreign Member Academia Europaea; Foreign Member, Estonian Academy of Sciences. He has also been the recipient of numerous prestigious awards, including the Distinguished Scientific Contribution Award (American Psychological Association), Gold Medal Award for Life Achievement in Psychological Science (American Psychological Foundation), and the Izaak Walton Killam Memorial Prize for Distinguished Career Contributions to the Field of Natural Sciences (Canada Council).

Jeffrey M. Friedman

2005
For contributions to our understanding of obesity and particularly for the discovery of the adipose tissue hormone, leptin.
Professor, Rockefeller University, New York, NY, USA

Jeffrey M. Friedman is a leader in the biology of the mechanisms that control body weight. In 1994 he completed an investigative "tour de force" that spanned nearly a decade when he discovered the genetic defect in the murine "obese" (ob) mutant. Leptin was the first fat cell-derived hormone to be discovered. Building on the seminal early work of Douglas Coleman (2005 Gairdner International Award Winner) he employed positional cloning approaches to characterize the defective gene well before the advent of today's repositories of gene sequence and sophisticated investigative genetic tools and informative DNA markers. The isolation of the gene rapidly led to his integrative studies which helped define the biological effects of leptin at the whole animal level and the elucidation of a genetic defect in the leptin receptor in the "diabetes" (db) mouse model of obesity. Taken together his work provided the "spark" that has ignited an international frenzy of academic and industry-based research into the study of the causes and treatment options for obesity. The discovery of leptin and newer studies defining the link between leptin released from fat cells and modulation of brain function by leptin have fundamentally advanced our understanding of the control of total body fat content.

Jeffrey M. Friedman, born in Orlando, Florida, received his medical degree from Albany Medical College of Union University and residency training in Internal Medicine at Albany Medical Center Hospital. He received his PhD degree in 1986 from the Rockefeller University and later joined the Faculty, where he is presently Professor and an Investigator of the Howard Hughes Medical Institute. Most recently, he has been awarded many accolades and awards including membership in the National Academy of Sciences (2001) and the Bristol-Meyers Squibb Award for Distinguished Achievement in Metabolic.

For the discovery of RNA interference which initiated a revolution in the study and use of RNA in gene silencing.
Professor, School of Medicine, Stanford University, Stanford, CA, USA

Andrew Fire, with his studies on gene regulation in the nematode Caenorhabditis elegans, has made important contributions to describing and elucidating mechanisms of gene silencing by double stranded RNA. This paradigm of gene silencing contributed to by the work of Fire has been described as "one of the most exciting discoveries of recent times in molecular biology". Much effort has been focused on the efficacy of a system that can use just a few molecules of dsRNA to silence a large population of target molecules. The underlying responses to these silencing triggers are present in many organisms, and in plants have clearly been shown to be involved in response to pathogenic challenges. These gene silencing processes in animal systems have a role in viral pathogenesis and in tumor progression in mammalian systems.

Andrew Fire is a native of Santa Clara County, California. Dr. Fire received training at UC Berkeley receiving a BA in mathematics in 1978. He received his PhD in biology from MIT in 1983 studying with Dr. Philip Sharp and did postdoctoral work at the Medical Research Council laboratory in Cambridge, UK in the group of Dr. Sydney Brenner from1983-1986. From 1986 to 2003, Dr. Fire was on the staff of the Carnegie Institution of Washington's Department of Embryology in Baltimore, Maryland during which time he was also Adjunct Professor of Biology at Johns Hopkins University. In 2003, Dr. Fire joined the faculty as Professor in the Departments of Pathology and Genetics at Stanford University School of Medicine. He is a member of the National Academy of Sciences and a recipient of many awards and prizes including the Wiley Prize, Rockefeller University in 2003, the National Academy of Sciences Molecular Biology Award in 2003, and the H.P.

Canada Gairdner International Award
2006
For his pioneering discoveries in germ line modifications in mammals.
Richard King Mellon Professor of Reproductive Physiology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, PA, USA

Dr. Ralph Brinster is a pioneer in the development of techniques for manipulating the cellular and genetic composition of early mouse embryos. These techniques have made the mouse the major genetic model for understanding the basis of human biology and disease. He began his work by showing how mouse embryos could be cultured in a Petri dish in a simple culture medium and then showing how cells could be added to such embryos to make animals of mixed cell origins or chimeras. This work was a key enabler of targeted mutagenesis in embryonic stem cells, which has revolutionized our ability to understand gene function in mammals. He is acknowledged as the founder of the field of mammalian transgenesis, with its applications to human disease models and biotechnology. In recent years he has developed new models of germline manipulation using sperm progenitor cell transplants. In all these studies, Dr. Brinster has been an innovator, a perfectionist and a forward thinker, understanding clearly the need to develop enabling technologies to pursue novel biological questions. His range of contributions is unmatched in the field.

Dr. Brinster grew up on a small farm in Cedar Grove, New Jersey, where some of his early experiences with animals included, as a teenager, running a small poultry business, which helped finance his studies in veterinary medicine. After completing his DVM and PhD studies at the University of Pennsylvania, he joined the faculty of the School of Veterinary Medicine there in 1960. He remains on faculty today as Richard King Mellon Professor of Reproductive Physiology in the School of Veterinary Medicine. He is a member of the National Academy and the Institute of Medicine and has received many awards and honours including the Wolf Prize, 2003 and the first March of Dimes Prize in Developmental Biology in 1996.

For his seminal studies defining new classes of nuclear hormone receptors and elucidating their role in energy metabolism and endocrine-related disease.
March of Dimes Chair in Molecular and Developmental Biology, The Salk Institute for Biological Studies, La Jolla, CA, USA

Ronald A. Evans' scientific contributions in the field of nuclear receptors and their function have been seminal. His work is in an area that has wide medical application. In 1985, his cloning and characterization of the first nuclear hormone receptor, the human glucocorticoid receptor, heralded a "molecular revolution" that transformed the field and, with it our understanding of how hormones, fat-soluble vitamins and dietary lipids elicit changes in gene expression in health and disease. In the years that followed, he uncovered nearly 50 such receptors that, taken together, constitute the nuclear receptor superfamily and represent an important mechanistic link between diet, exercise and a myriad of human diseases, including cancers, diabetes and osteoporosis. Particularly noteworthy was the discovery of the peroxisome proliferator-activated receptor (PPAR) family of orphan receptors that provided "a molecular interface between dietary fats and the genome."

Ronald M. Evans, born in East Los Angeles, California, received his BA in Bacteriology (1970) and PhD in Microbiology (1974) at the University of California, Los Angeles (UCLA). He completed postdoctoral work at the Rockefeller University in New York in the laboratory of Dr. James Darnell. In 1978, he joined the faculty of the Salk Institute for Biological Studies in La Jolla, California. He is currently the March of Dimes Chair in Molecular and Developmental Biology at the Salk Institute and an Investigator of the Howard Hughes Medical Institute. He is a recipient of numerous awards including membership in the National Academy of Sciences (1989), the 1st Bristol-Meyers Squibb Award for Distinguished Achievement in Metabolic Research (2000), the Albert Lasker Basic Medical Research Award (2004) and the "Grande Medaille D'Or" from the French Academy of Sciences.

Alan Hall
PHD FRS
Canada Gairdner International Award
2006
For his discoveries related to understanding the cytoskeleton of the cell and the basis of cell mobility and its relevance to human disease.
Chair, Department of Cell Biology, Memorial Sloan-Kettering Cancer Center, New York, NY, USA

Prof. Alan Hall has been a pioneer in showing how external signals control the cellular cytoskeleton, composed of proteins such as actin, which in turn organizes the shape and movement of cells. His research revealed a series of crucial molecular switches (called Rho GTPases), which acting together determine when and where the cell's outer membrane and actin cytoskeleton become rearranged to drive changes in cell migration. These are crucial features of cellular function in normal tissues, and critical for the aberrant behaviour of cancer cells. Dr. Hall's work has therefore transformed our understanding of the biology of human cells.

Prof. Hall was born in England and received his BA in Chemistry at Oxford. He obtained his PhD from Harvard University (1977).

Thomas D. Pollard
MD
Canada Gairdner International Award
2006
For his discoveries related to understanding the cytoskeleton of the cell and the basis of cell mobility and its relevance to human disease.
Chair, Department of Molecular, Cellular & Developmental Biology, Yale University, New Haven, CT, USA

Dr. Thomas Pollard pioneered the biochemical and biophysical analysis of the actin cytoskeleton, which is responsible for form and movement in all cells. His many contributions have defined the actin cytoskeleton field for nearly three decades, and include the basis for directional actin polymerization, the discovery of actin capping, severing and nucleation factors and the mechanisms of actin-based intracellular movement. The complex actin-based cytoskeletal network underlies cell shape and motility in virtually all biological contexts, including intracellular transport, polarized cell growth and division, tissue formation and developmental morphogenesis. In addition, actin dynamics is essential for virulence of a number of human bacterial pathogens.

Dr. Thomas Pollard obtained his MD from Harvard Medical School (1968) and became a staff associate at the National Institutes of Health in 1969. He returned to Harvard in 1972, and was promoted to Associate Professor (1975). He was Professor and Director of the Department of Cell Biology and Anatomy at Johns Hopkins Medical School from 1987-1996. He assumed the Presidency of the Salk Institute in 1996, where he was also Professor and an Adjunct Professor at UCSD. He moved to Yale University in 2001, where he is currently the Eugene Higgins Professor and Chair of the Department of Molecular, Cellular and Developmental Biology.

C. David Allis
PHD
Canada Gairdner International Award
2007
For his transforming studies demonstrating the link between chromatin structure and gene transcription and elucidating the mechanisms by which a variety of post-translational modifications of histones are involved in gene expression and genome maintenance and stability.
Head, Laboratory of Chromatin Biology, Rockefeller University, New York, NY, USA

C. David Allis is a leader in the field of chromatin biology. He has pioneered experimental and theoretical studies elucidating the mechanisms by which post-translational modifications of histones regulate the functions of chromatin. His studies demonstrating the identity between biochemically purified histone modifying enzymes and genetically defined transcription co-activators established a critical link between covalent histone modifications and gene activation and opened a new era in chromatin biology and our understanding of genome function. He proposed and refined the current paradigm referred to as the 'histone code hypothesis' to explain how cell signaling cascades result in individual or combinatorial histone modifications, forming an epigenetic code that dictates specific functional outcomes through downstream interactions with distinct combinations of transcriptional regulatory factors. His research has been driven by his development of novel methods for studying protein modifications that are now mainstream in the field. His work has brought together the fields of chromatin biology and genome function and has had major impact on the basic fields of genetics, cell, developmental, and molecular biology with major impact for the understanding of abnormal development and cancer.

A native of Cincinnati, Ohio Dr Allis received a PhD from Indiana University (1978). Following postdoctoral studies (1978-1981) at the University of Rochester, he has held academic positions at Baylor College of Medicine as Assistant Professor (1981) to Professor (1988), Syracuse University,University of Rochester (Marie and Joseph Wilson Professor, Departments of Biology and Oncology), and the University of Virginia Health System (Harry F. Byrd Jr. Professor of Biochemistry and Molecular Genetics). Since 2002, he has been Joy and Jack Fishman Professor and Head, Laboratory of Chromatin Biology, The Rockefeller University. He has been elected to numerous prestigious societies including Phi Beta Kappa, the American Academy of Arts and Sciences, The American Academy of Microbiology, the Harvey Society, the American Society for Biochemistry and Molecular Biology, and the National Academy of Sciences. He has received numerous awards including the Syracuse University William J. Wasserman Prize, the University of Rochester Davey Award, the Baxter Award for Distinguished Research, the Massry Prize, and the John Wiley Prize, to name a few. He has presented many Distinguished Lectures, has published over 240 scientific papers, and is co-editor of a recent ground breaking book on Epigenetics.

Kim Nasmyth
PHD
Canada Gairdner International Award
2007
For his discovery of the mechanism of chromosome segregation during cell division, which has profound implications for our understanding of chromosome non-disjunction in human cancer and other genetic diseases.
Whitley Chair, Department of Biochemistry, Oxford University, Oxford, UK

Proper chromosome segregation during mitosis is essential for all life, and has been one of the outstanding problems in cell biology for over 100 years. Nasmyth has dominated the field of mitotic regulation with a series of incisive discoveries, including characterization of the anaphase promoting complex that degrades mitotic cyclins, the cohesin complex that links sister chromatids together prior to mitosis, and most importantly, the novel proteolytic mechanism that rapidly breaks up sister chromatid cohesion at the onset of mitosis. Nasmyth's work on fundamental aspects of cell divison has profound implications for our understanding of chromosome non-disjunction in human cancer and other genetic diseases.

Kim Nasmyth obtained his PhD from the University of Edinburgh (1977), followed by postdoctoral training with Ben Hall at the University of Washington. From 1980-81 he was a Robertson Fellow at Cold Spring Harbor Laboratory, before becoming a staff member at the Laboratory for Molecular Biology in Cambridge (1982-1987).

2007
For his studies on the structure and function of the ribosome which showed that the peptidyl transferase was an RNA catalyzed reaction, and for revealing the mechanism of inhibition of this function by antibiotics.
Director, Center for Molecular Biology, University of California Santa Cruz, Santa Cruz, CA, USA

Harry F. Noller's work has led to fundamental changes in our thinking about the role of RNA in the many steps of protein synthesis. He has used the full range of techniques including traditional biochemical as well as high resolution structural analysis to elucidate mechanisms of protein synthesis. His contributions to the sequencing and of genes encoding ribosomal RNAs and to phylogenetic and other analysis of these data led to insights into the secondary structure of these molecules and to functional inferences. Chemical probing and crosslinking experiments provided the key insights to appreciate the possibility that the peptidyl transferase activity of the large subunit of the ribosome may comprise RNA. His subsequent refined structural analysis building on results from biochemical analysis of stripping of proteins from the large ribosomal subunit and assaying for peptidyl transferase activity has provided a significant contribution to the full understanding of RNA catalysis of peptide bond synthesis and other aspects of ribosome structure and function and protein synthesis.

A native of Oakland, California, Harry Noller received PhD in Chemistry from the University of Oregon (1965). Following postdoctoral work at the Medical Research Council Laboratory of Molecular Biology, Cambridge and the Institute of Molecular Biology, University of Geneva, he joined the Department of Biology, University of California, Santa Cruz as Assistant Professor (1968), becoming Professor in 1979. He has been Robert L. Sinsheimer Professor of Molecular Biology since 1987 and since 1992, Director, Center for Molecular Biology. He was Sherman Fairchild Distinguished Scholar, Division of Biology, California Institute of Technology (1989-1990).

He is a member of the American Academy of Microbiology, the American Academy of Arts and Sciences, The RNA Society, The National Academy of Sciences, and The American Association for the Advancement of Science and others. He presented the Harvey Lecture at Rockefeller University (1989), and has received the Rosensteil Award in Basic Biomedical Science (2001), AAAS Newcomb Cleveland Prize (2002), Speaker of the Year, Netherlands Society for Biochemistry and Molecular Biology (2002), RNA Society Lifetime Achievement Award (2003), Massry Prize (2004), and the Paul Ehrlich and Ludwig Darmstaedter Prize (2007).

For his studies on the structure and function of the ribosome which showed that the peptidyl transferase was an RNA catalyzed reaction, and for revealing the mechanism of inhibition of this function by antibiotics.
Sterling Professor of Molecular Biophysics and Biochemistry, Yale University, New Haven, CT, USA

Thomas Steitz's scientific career has involved studies of biological structure using X-ray crystallography including developing and refining novel techniques to determine the structure of proteins and nucleic acids with the focus of addressing questions of biological function and mechanism of action. Much of his work has been directed to understanding the structural basis of enzyme mechanisms and on protein-nucleic acid interactions.

His earliest studies on protein structure and mechanism of enzyme action include work on yeast hexokinase demonstrating that substrate binding induces a large conformational change in the enzyme providing experimental support for the induced fit mechanism of enzyme specificity. Subsequently, his work has focused on providing a structural basis for understanding the mechanisms and specificity of gene expression including replication, genetic recombination, transcription, reverse transcription, and translation, the work cited for this award.

He provided the first structure of a DNA polymerase, a bacterial polymerase, followed by studies on mammalian polymerases and the HIV reverse transcriptase. These studies and elucidating structures of recombination enzymes, RNA polymerases, transcription factors, and aminoacyl tRNA synthetases have all provided important and in many cases unexpected insights into biological function in pathways involved in information transfer and genome stability and change. His structural studies on the large ribosomal subunit provided the first atomic level insights into the structure and function of the ribosome, the site of protein synthesis in the cell.

Further studies have refined insights into principles of RNA folding, stability, and RNA-protein interaction, and have also addressed questions of the mechanisms of peptide bond formation and other aspects of protein synthesis on the ribosome. Structures of complexes between the large subunit and antibiotics make possible the structure-based design of new antibiotics potentially active against antibiotic resistant microorganisms.

Tom Steitz is a co-founder and Chairperson of the Scientific Advisory Board of a company involved in the translation of the basic studies of the ribosome to be applied to the development of important health care products, effective antibiotics active against presently antibiotic resistant microorganisms. Likely the most significant outcome of the studies on the ribosome from the Steitz lab is the elucidation of the chemical mechanism of RNA catalyzed peptide bond formation and the key role of RNA in ribosome structure and function; the ribosome is a ribozyme.

For the discovery of the causative role of papilloma viruses in cancer of the cervix which led to the development of a successful HPV vaccine.
Emeritus Professor, German Cancer Research Centre, Heidelberg, Germany

Prof. zur Hausen received his MD in 1960 from the University of Dusseldorf. After receiving further medical training, he was a research fellow first at the University of Dusseldorf 1962-1965, and then at the Children's Hospital of Philadelphia, 1966-1969, where he worked under Prof. Werner Henle. In 1969, he returned to Germany, at the University of Wurzburg, as a Senior Scientist at the Institute for Virology. During 1972-1977, he was the Chairman and Professor in the Institute for Clinical Virology at the University of Erlangen-Nurnberg, and then during 1977-1983 the Chairman and Professor at the Institute for Virology at the University of Freiburg. From 1983 until 2003, he was the Scientific Director and Chairman of the Management Board of the German Cancer Research Center (DKFZ) in Heidelberg. In 2003, he became an emeritus professor at the German Cancer Research Center. Prof. zur Hausen's laboratory has made several particularly noteworthy findings in papillomavirus research. The earliest was the recognition that there are multiple HPV genotypes, particularly that the HPVs that caused non-genital warts and those that caused genital warts might be distinct (2,3). Prior to his studies, it was believed that there might be a single HPV, as it had been shown in the first part of the 20th century that cutaneous warts could be induced with filtrates from genital or laryngeal warts.

His most important finding was the identification and molecular cloning of the HPV16 and HPV18 genomes, and the associated demonstration that a majority of cervical cancers contained DNA that hybridized under stringent conditions to probes from HPV16 or HPV18 and that an even higher proportion of cervical cancers would hybridize to these probes under less stringent conditions. These observations strongly implied: 1) papillomaviruses were etiologically involved in this cancer; 2) infection by more than one HPV type could result in cervical cancer; and 3) there were additional related HPV types that also caused cervical cancer. Indeed, subsequent research has indicated that infection by more than 10 other HPVs that are phylogenetically related to HPV16 and HPV18 are also in cervical cancer. HPV16 and 18 are the most oncogenic, accounting for about 70% of cervical cancer.The third critical finding was that the HPV DNA was integrated into the host genome in cervical cancer cell lines and the associated demonstration that the viral E6 and E7 genes were preferentially retained and expressed in the tumors. These observations provided a mechanism for the efficient transfer of viral DNA progeny cells, implied that viral gene expression might be required for maintenance of the tumorigenic phenotype, and that E6 and E7 probably represented key viral oncogenes.The findings related to HPV16 and HPV18 formed the basis for subsequent epidemiologic studies confirming that infection by a subset of HPV types, most notably HPV16 and HPV18, accounts for virtually all cervical cancers. In addition to the role of HPV in cervical cancer, other evidence has led to the conclusion that a substantial proportion of several additional types of cancer are also caused by HPV infection. These include various genital cancers (such as vulvar and penile cancers), anal cancers, and head-and-neck cancers.

Prof. zur Hausen has continued to run a highly productive laboratory since making the above seminal findings, publishing an average of more than 5 papers per year. Some of the more important findings made during this period include: 1) finding that most Buschke-Loewenstein tumors, which are large but low-grade malignant penile tumors, contain HPV6 or HPV11, which usually do not cause malignancy at other sites; determining that E6 and E7 expression in cervical cancer cell lines is required for maintaining the transformed phenotype; finding that HPV DNA in cervical tumors may be integrated near the c-Myc oncogene and be associated with its activation; the isolation of several new HPV types and their clinical importance; epidemiological studies delineating the prevalence of genital HPV infection and the risk of progression dysplasia or cancer; identification of cellular transcription factors that interact with the main HPV promoter; and the role of AP-1, Fos, and Fra-1 in regulating HPV transcription. He has also been a highly sought after and effective spokesman for the papillomavirus research community and for the role of viruses in human cancer.

Gary Ruvkun
PHD
Canada Gairdner International Award
2008
For the discovery and characterization of micro RNA's, important in the regulations of gene function.
Professor of Genetics, Harvard Medical School, Boston, MA, USA

Gary Ruvkun is a professor of genetics at Harvard Medical School. Dr. Ruvkun is a graduate of UC Berkeley and Harvard. His PhD thesis with Fred Ausubel explored the symbiotic nitrogen fixation genes of Rhizobium. Dr. Ruvkun began to work with C. elegans as a postdoc with Bob Horvitz at MIT and Walter Gilbert at Harvard, where he collaborated with fellow postdoctoral fellow Victor Ambros on the molecular analysis of the heterochronic genes.

The work on miRNAs and their target mRNA genes by Ambros and Ruvkun began in 1982 when they targeted the lin-14 gene for molecular analysis. The genetic analysis that Ambros and Horvitz had done suggested that the gene lin-4 negatively regulates lin-14 but the molecular basis of that regulatory axis was not known. In the Horvitz lab, Ruvkun and Ambros had to develop new technologies to allow such genetically defined loci to be analyzed molecularly, and they succeeded to isolate the lin-14 gene. This work continued in their own labs at Harvard, starting in 1984 for Ambros and 1985 for Ruvkun. The first hint that the key regulatory element of the lin-14 gene was in its 3' untranslated region came from the molecular analysis of lin-14 gain-of-function mutations, showing that they are deletions of conserved elements in the lin-14 3' untranslated region that relieve the normal late stage-specific repression of LIN-14 protein production, and showing that lin-4 is necessary for that repression. The Ambros lab discovered in 1993 that lin-4 encodes a very small RNA product. When Ambros and Ruvkun compared the sequence of the lin-4 miRNA and the lin-14 3' untranslated region, they discovered that the lin-4 RNA base pairs with conserved bulges and loops to the 3' untranslated region of the lin-14 target mRNA to downregulate its translation, and that deletions in the lin-14 3' UTR complementary sites, which are conserved in evolution, relieve the repression normally induced by base pairing to the lin-4 miRNA These papers revealed a world of RNA regulation at an unprecedented small size scale and the mechanism of that regulation.

In 2000, the Ruvkun lab, again in collaboration with the Ambros and Horvitz labs, reported in Nature the identification of second microRNA, let-7, which like the first microRNA regulates translation of the target gene lin-41 via imperfect base pairing to the 3' untranslated region of that mRNA. This was the first indication that miRNA regulation via 3' UTR complementarity was a general phenomenon.

The microRNA field was shown to be general in biology with the publication from the Ruvkun lab of a second Nature paper in 2000 reporting that the sequence and regulation of the let-7 microRNA is conserved across animal phylogeny, including in humans. Presently thousands of miRNAs have been discovered, pointing to a world of gene regulation at this size regime.

Dr. Ruvkun lab has also identified protein coding genes that constitute a genetic pathway for the regulatory function of miRNAs and siRNAs and other small RNAs. In a 2005 Nature paper, the Ruvkun lab reported that mutations in the retinoblastoma ortholog of C. elegans dramatically activates RNAi, and that cell lineage defects in animals with defective retinoblastoma could be reversed by inactivating particular RNAi pathway genes. This revealed that small RNAs are likely to mediate the dysregulations of cell cycle during tumor formation, a previously unsuspected regulatory modality in tumor formation. In addition to revealing fundamental regulatory axes in biology, some of these components may be developed as drug targets to enhance RNAi in mammals, a technical improvement that may be necessary to elevate a laboratory tool to a therapeutic modality.

Dr. Ruvkun has also worked in other fields, such as control of longevity and fat storage, where his lab discovered for example that insulin signaling is key to longevity in C. elegans. Dr. Ruvkun has an active research program in microbiology, searching for deeply divergent microbial life, even on other planets.

2008
For the discovery and characterization of micro RNA's, important in the regulation of gene function.
Professor, University of Massachusetts Medical School, Worcester, MA, USA

Victor Ambros grew up in Vermont and graduated from MIT in 1975. He did his graduate research (1976-1979) with David Baltimore at MIT, studying poliovirus genome structure and replication. He began to study the genetic pathways controlling developmental timing in the nematodeC. elegansas a postdoc in H. Robert Horvitz's lab at MIT, and continued those studies while on the faculty of Harvard (1984-1992) Dartmouth (1992-2007), and the University of Massachusetts Medical School (2008-present). In 1993, members of the Ambros lab identified the first microRNA, the product oflin-4, a heterochronic gene ofC. elegans. Since then, the role of microRNAs in development has been a major focus of his research.

Primarily a developmental biologist, Prof. Ambros is interested in the genetic regulatory mechanisms that control animal development, and in particular the molecules that function during animal development to ensure the proper timing of developmental events. He has primarily employed the nematodeCaenorhabditis elegansas a model system for studying the function of regulators of developmental timing, which inC. elegansare known as the "heterochronic genes", in reference to the remarkable changes in relative timing of developmental event that are elicited by mutations in these genes. The heterochronic genes comprise a set of interrelated regulatory pathways that include proteins that regulate the transcription of other genes, and also a class of small RNA, known as microRNAs, that regulate the production of protein by the messenger RNAs of specific target genes. Much of his research in recent years has been aimed at understanding how microRNAs are integrated into broader regulatory networks related to animal development and human disease, and at uncovering the molecular mechanisms for how microRNAs exert their effects on gene expression.

Nahum Sonenberg
PHD
Canada Gairdner International Award
2008
For his pioneering discoveries in cellular translation of genetic information.
James McGill Professor, Department of Biochemistry, McGill University, Montreal, QC, Canada

Dr. Sonenberg received his BSc and MSc (Microbiology and Immunology) from Tel-Aviv University. Upon completing his Ph.D. (Biochemistry) at the Weizmann Institute of Science (Rehovot, Israel), he joined the Roche Institute of Molecular Biology in Nutley, New Jersey with a Chaim Weizmann postdoctoral fellowship. He joined McGill University in 1979, and is currently the James McGill Professor in the Department of Biochemistry and the McGill Cancer Centre.

Dr. Sonenberg's primary research interest has been the control of protein synthesis. He identified the mRNA 5' cap-binding protein, eIF4E, in 1978. He later discovered the IRES (internal ribosome entry site) mechanism of translation initiation in eukaryotes, as well as the regulation of cap-dependent translation by the eIF4E binding proteins (4E-BPs). He also discovered that eIF4E is a proto-oncogene, levels of which are elevated in cancer, and subsequently demonstrated that rapamycin (an important anti-cancer drug) inhibits eIF4E activity. Finally, while generating 4E-BP 'knock-out' mice, he and his colleagues found that this translation inhibitor plays critical roles in the metabolism of adipose tissue, and learning and memory.

In 2002, Dr. Sonenberg was awarded the Robert L. Noble Prize from the National Cancer Institute of Canada. He is an International Research Scholar of the Howard Hughes Medical Institute, a Canadian Institutes of Health Research Distinguished Scientist and has been a fellow of the Royal Society of Canada since 1992. Dr. Sonenberg has recently been awarded the Killam Prize for Health Sciences.

Professor, University of California San Francisco, San Francisco, CA, USA

Inside the cell, many newly made proteins pass through a maze-like structure of membranes, where they are folded and groomed into their final shapes before being shipped to precise destinations to carry out their functions. This structure, called the endoplasmic reticulum, enforces strict quality control standards to help ensure that defective or misfolded proteins are not allowed to leave. Peter Walter expores the signaling pathway by which cells alter their quantities of endoplasmic reticulum. This communication process is so crucial to cells that imbalances can lead to a number of diseases, including cancer, diabetes, cystic fibrosis, and vascular and neurodegenerative diseases.

Growing up in his native Germany, Walter spent hours in his father's West Berlin "chemist shop," a drugstore where medicines and chemicals were mixed and sold. This exposure-along with his own dabbling in the pyrotechnical adventures of mixing chemicals-fostered Walter's early interest in science. By age 12, he knew he wanted to be a chemist. He came to Vanderbilt University as a graduate student, part of a nine-month exchange program in organic chemistry. Walter's main intent was to immerse himself in the English language, a prerequisite he thought necessary to further his research career. He quickly discovered, however, that American universities offered scientists-to-be more hands-on experience and training to eventually work as independent researchers. Walter became hooked on this style of learning and never left.

As a PhD student at the Rockefeller University in the late 1970s, Walter worked with Günter Blobel, an HHMI investigator and winner of the 1999 Nobel Prize in Physiology or Medicine for his discovery of the mechanisms that proteins use to find their correct locations within the cell. Blobel had postulated that newly synthesized proteins contain built-in signals, or address tags, that direct them to their proper destinations, but it remained unclear how the address tags were recognized. That problem was solved when Walter identified the six proteins and the small bit of RNA that make up the signal recognition particle. The identification of this particle was central to Blobel's hypothesis. To this day, Walter continues to study the signals used by proteins to ensure they are shuttled to their proper destinations.

In his laboratory at the University of California, San Francisco, Walter also has turned his attention to deciphering the pathways that cells use to regulate the abundance of their organelles. With a particular focus on the endoplasmic reticulum (ER), he has uncovered a feedback loop within cells called the "unfolded protein response." Working with yeast as a model, his pioneering studies have shown that cells need the right amount of ER to properly fold newly assembled proteins. The same principles also apply in higher organisms, including humans. "Regulating how much ER you have is a fundamental process for cells, and it is a key determinant for any number of diseases," Walter noted. "By understanding the details of this mechanism, we hope to make significant contributions to understanding many medically important pathologies."

Kazutoshi Mori
PHD
Canada Gairdner International Award
2009
For the dissection and elucidation of a key pathway in the unfolded protein response which regulates protein folding in the cell.
Professor, Graduate School of Science, Kyoto University, Kyoto, Japan

Proteins must be correctly folded and assembled to fulfill their functions as assigned by genetic code. Unfolding or misfolding of proteins constitutes a fundamental threat to all living cells. In eukaryotes, proteins can be unfolded or misfolded in a variety of subcellular compartments, but the risk of protein misfolding is particularly acute in the endoplasmic reticulum, in which newly synthesized secretory and transmembrane proteins attain their proper tertiary structure. With their pioneering work on an intracellular signaling pathway called the 'Unfolded Protein Response', Dr. Mori, together with Dr. Walter, has elucidated the molecular mechanisms by which cells adjust their capacity for protein folding and quality control according to need. Their work provides answers to the fundamental question of how cells maintain a proper abundance of organelles and has far reaching implications for our understanding of the development of specialized cell types and various diseases, including protein folding disorders, diabetes, heart diseases, atherosclerosis and cancer.

Dr. Kazutoshi Mori is a professor at the Graduate School of Science, Kyoto University since 2003. He graduated from the Graduate School of Pharmaceutical Sciences, Kyoto University. He was Instructor at Gifu Pharmaceutical University from 1985 to 1989, and then worked as a postdoctoral fellow at the University of Texas Southwestern Medical Center at Dallas from 1989 to 1993 (under supervision from Drs. Mary-Jane Gething and Joe Sambrook). He was Deputy Research Manager from 1993 to 1996 and Research Manager from 1996 to 1999 at the HSP Research Institute in Kyoto (directed by Dr. Takashi Yura).

Richard Losick
PHD
Canada Gairdner International Award
2009
For the discovery of mechanisms that define cell polarity and asymmetric cell division, processes key in cell differentiation and in the generation of cell diversity.
Professor of Biology, Harvard University, Cambridge, MA, USA

Studying the molecular mechanisms by which cells switch identity was a passion throughout Prof. Losick's career. He tackled this problem in a primitive organism, a bacterium that can either grow and divide or transform itself into a dormant cell known as a spore. Making a spore involves two cells, one that will become the spore and one that nurtures the developing spore. Prof. Losick and his colleagues discovered mechanisms by which a cell divides asymmetrically to give rise to the developing spore and the nurturing cell. They discovered an important class of regulatory proteins that controls the expression of large blocks of genes during spore formation and as we now know in many other kinds of bacteria as well. They elucidated exquisitely intricate mechanisms orchestrating the expression of hundreds of genes and ensuring that they are switched on at the right time and the right place. Dr. Losick and his colleagues also discovered that the protein products of those genes have distinctive subcellular addresses and localize in a choreographed movement, that the developing spore and the nurturing cell talk to each other in a chemical code that keeps events in one cell in register with events in the sister cell, and elucidated the molecular mechanisms by which these conversations takes place. Understanding bacteria is important to humanity because microbes are both beneficial and the causative agent of many diseases. The human body is a host to ten times more bacteria than human cells and bacteria are important agents of change in our environment and in Earth's history. Some microbes are pathogens whereas others are sources of medicines. Fundamental studies of bacteria inform efforts to combat infections and to harness the microbial world for the benefit of humanity.

Richard Losick is the Maria Moors Cabot Professor of Biology, a Harvard College Professor, and a Howard Hughes Medical Institute Professor in the Faculty of Arts & Sciences at Harvard University. He received his AB in Chemistry at Princeton University and his PhD in Biochemistry at the Massachusetts Institute of Technology. Upon completion of his graduate work, Professor Losick was named a Junior Fellow of the Harvard Society of Fellows when he began his studies on RNA polymerase and the regulation of gene transcription in bacteria. Professor Losick is a past Chairman of the Departments of Cellular and Developmental Biology and Molecular and Cellular Biology at Harvard University. He received the Camille and Henry Dreyfuss Teacher-Scholar Award, and he is a member of the National Academy of Sciences, a Fellow of the American Academy of Arts and Sciences, a Member of the American Philosophical Society, a Fellow of the American Association for the Advancement of Science, a Fellow of the American Academy of Microbiology, and a former Visiting Scholar of the Phi Beta Kappa Society.

Nubia Muñoz
MD MPH
John Dirks Canada Gairdner Global Health Award
2009
For her epidemiological studies that defined the essential role of the human papilloma virus in the etiology of cervical cancer on a global level which led to the development of successful prophylactic vaccines.
Visiting Scientist, Catalan Institute of Oncology, Barcelona, Spain; Emeritus Professor, National Cancer Institute, Bogota, Colombia

Nubia graduated from the School of Medicine at Universidad del Valle in 1964. After graduation from Universidad del Valle, she worked for three years in the National Cancer Institute in Bethesda, where the headquarters of the National Health Institute is located. She got a Master's Degree in Public Health specializing in Epidemiology and Virology of Cancer in the School of Public Health of Johns Hopkins University in Baltimore. Then, she went to Lyon, France, to continue her research at the International Agency for Research of Cancer (IARC), which belongs to the World Health Organization.

Nubia Muñoz is a former winner of the First Richard Doll Prize in Epidemiology for proving that HPV causes cervical cancer. Her story is a remarkable one and will undoubtedly go down in the annals of epidemiology as an example par excellence of what all epidemiologists aspire to and can accomplish in studying the etiology of a disease.

Nubia Muñoz was a Postgraduate student, School of Public Health, 1968 to 1969, at Johns Hopkins. Nubia Munoz' work at the International Agency for Research on Cancer in Lyon, France, and with teams across the world led to establishing the relationship between the human papillomavirus and cervical cancers. This recognition of a viral cause of cervical cancer has led to the development of vaccines that would prevent these infections and that hold promise for the control and possible elimination of this cancer.

Nubia Muñoz was inducted in the Johns Hopkins Society of Scholars in 2004. This induction is to honor the significant accomplishments of men and women who spent part of their careers at Johns Hopkins. The society - the first of its kind in the USA - inducts former postdoctoral fellows and junior or visiting faculty at Johns Hopkins who have gained marked distinction in their fields of physical, biological, medical, social or engineering sciences or in the humanities and for whom at least five years have elapsed since their last Hopkins affiliation.

Michael W. Young
PHD
Canada Gairdner International Award
2012
For his pioneering discoveries concerning the biological clock responsible for circadian rhythms.
Richard and Jeanne Fisher Professor; VP Academic Affairs; Head, Laboratory of Genetics, Rockefeller University, New York, NY, USA

The challenge: How does our internal biological clock control the timing of our bodies throughout the day?

The work: With Drs. Michael Rosbash and Jeffrey Hall, Young discovered that our circadian clocks are regulated by a small group of genes that work at the level of the individual cell. Subtle mutations in any of these genes can accelerate or slow our daily rhythms.

Why it matters: Their discoveries about the biological clock have applications for sleep and appetite disorders. There are also applications for organs such as the brain, liver, lungs and skin, which use the same genetic mechanisms to control their rhythmic activities.

Bio
Dr. Young received his PhD in genetics from the University of Texas (1975). He did postdoctoral work at Stanford before moving to Rockefeller. In 1991 he became head of the Rockefeller unit for the National Science Foundation's Science and Technology Center for Biological Timing. He was appointed Vice President Academic Affairs (2004) and was named Richard and Jeanne Fisher Professor the same year.

His work at Rockefeller has focused on two areas: neuromuscular development – stemming from the laboratory's isolation and study of the Notch locus of Drosophila – and the genetics of behavior, particularly circadian rhythms (including initial cloning of the period gene of Drosophila, discovery and functional characterizations of the circadian clock genes timeless, double-time, shaggy, vrille, and pdp1, and modeling of principal molecular features of the Drosophila circadian system).

Dr. Young was an investigator at the Howard Hughes Medical Institute (1987-1996) and is a member of the National Academy of Sciences and a Fellow of the American Academy of Microbiology. Among Dr. Young's awards are the 2009 Neuroscience Prize of the Peter and Patricia Gruber Foundation and the 2011 Louisa Gross Horwitz Prize of Columbia University.

Michael Rosbash
PHD
Canada Gairdner International Award
2012
For his pioneering discoveries concerning the biological clock responsible for circadian rhythms.
Peter Gruber Professor of Neuroscience, Brandeis University, Waltham, MA, USA

The challenge: How does our internal biological clock guide our bodies throughout the day?

The work: Along with Drs. Jeffrey Hall and Michael Young, Rosbash discovered that our circadian clocks are regulated by a small group of genes that work at the level of the individual cell. Subtle mutations in any of these genes can accelerate or slow our daily rhythms.

Why it matters: Their discoveries about the biological clock have applications for sleep and appetite disorders. There are also applications for organs such as the brain, liver, lungs and skin, which use the same genetic mechanisms to control their rhythmic activities

Bio
Michael Rosbash was instrumental in revealing the molecular basis of circadian rhythms, the built-in biological clock that regulates sleep and wakefulness, activity and rest, hormone levels, body temperature, and other functions. Using the fruit fly Drosophila, he identified genes and proteins involved in regulating the clock and proposed a theory of how the clock works. Rosbash's discoveries apply to humans and other mammals, and they could ultimately lead to the development of drugs to treat insomnia, jet lag, and other sleep disorders.

After Rosbash came to Brandeis, he became increasingly interested in the influence of genes on behavior. In 1974 he began working with Jeffrey Hall, and in 1984 they cloned the period gene. Several years later, they proposed a mechanism by which a molecular 24-hour clock might work: a transcriptional negative-feedback loop. Their model still holds up, despite discoveries of additional circadian rhythm genes. In essence, the genes that are part of this loop activate the production of key proteins until a critical activity of each accumulates and turns off transcription.

Jeffrey Ravetch
PHD MD
Canada Gairdner International Award
2012
For his seminal work on identifying the Fc receptors of antibodies, which play a key role in the immune response, and for establishing their critical role in autoimmune diseases and cancer.
Theresa and Eugene Lang Professor; Head, Leonard Wagner Laboratory of Molecular Genetics and Immunology, Rockefeller University, New York, NY, USA

The challenge: Antibodies work in the immune system to defend against bacteria and viruses. But antibodies can also trigger diseases such as arthritis and lupus.

The work: Dr. Ravetch discovered how antibodies can trigger different outcomes by binding to molecules (called Fc receptors) to change their activity. The Fc receptor allows antibodies to defend against toxins, bacteria and viruses.

Why it matters: The discovery of the Fc Receptor has changed how we think about the immune system by explaining the receptor’s puzzling dual nature as both protective and harmful. This knowledge paves the way to developing new therapies to fight autoimmune diseases such as lupus, arthritis and cancer.

Bio
Jeffrey V. Ravetch, received his training at the Rockefeller University – Cornell Medical School MD/PhD program. He earned his doctorate in 1978 in genetics with Norton Zinder and Peter Model, investigating the genetics of viral replication and gene expression for the single stranded DNA bacteriophage f1. In 1979 he earned his MD from Cornell University Medical School. He continued his training as fellow at the NIH (pursuing postdoctoral studies with Phil Leder), where he identified and characterized the genes for human antibodies and the DNA elements involved in switch recombination. From 1982 to 1996, Dr. Ravetch was a member of the faculty of Memorial Sloan-Kettering Cancer Center and Cornell Medical College. His laboratory has focused on the mechanisms by which antibodies mediate their diverse biological activities in vivo – establishing the pre-eminence of FcR pathways in inflammation and tolerance and describing novel inhibitory signalling pathways to account for the paradoxical roles of antibodies as promoting and suppressing inflammation.

Dr. Ravetch has received numerous awards, including the Burroughs-Wellcome Scholar Award, the Pew Scholar Award, the Boyer Award, the NIH Merit Award, the Lee C. Howley, Sr. Prize, the AAI-Huang Foundation Meritorious Career Award and the William B. Coley Award. He has presented numerous named lectures including the Kunkel Lecture, the Ecker Lecture, the Goidl Lecture, the Grabar Lecture and the Dyer Lecture. He was elected to the National Academy of Sciences in 2006 and to its Institute of Medicine in 2007. In 2008 he was elected a Fellow of the American Academy of Arts and Sciences. In 2009 he became a Fellow of the American Association for the Advancement of Science.

2012
For research in defining the genetic and molecular pathways leading to the complex development of the spinal cord, with implications for therapeutic applications.
Co-Director, Kavli Institute for Brain Science, Columbia University Medical Center, New York, NY, USA

The challenge: The nervous system sends signals from our brain to different parts of our body via circuits. This allows us to see, move and process thoughts. However, accidental paralysis or neurodegenerative diseases interrupt these circuits.

The work: Dr. Jessell discovered the genetic and molecular pathways that lead to the complex development of the spinal cord. This enhances our understanding of how our nervous system communicates.

Why it matters: By understanding how sensory neurons and motor neurons communicate, we can fix the broken circuits and treat or cure traumatic damage caused by disease like ALS, stroke or spinal cord injury.

Brian M. Greenwood
MD
John Dirks Canada Gairdner Global Health Award
2012
For contributions to significantly reducing mortality in children due to meningitis and acute respiratory infection, and for contributions to malaria prevention.
Manson Professor of Clinical Tropical Medicine, London School of Hygiene and Tropical Medicine, London, UK

The challenge: Meningitis, pneumonia and malaria – all dictated by seasonal climate – kill millions of children in the developing world each year.

The work: Malaria is widespread during the rainy season. Greenwood demonstrated the value of insecticide-coated bed nets and drug therapy in preventing malaria. Pneumonia and meningitis are most prevalent during the dry season. Greenwood developed and tested two groups of vaccines against these infections, which have been highly effective in saving children’s lives.

Why it matters: Dr. Greenwood has been a tireless advocate of children’s health in developing countries by battling the spread of disease and training post-doctoral scientists in Africa.

Bio
Brian Greenwood studied medicine at Cambridge (1962) followed by three years in Western Nigeria at University College Hospital, Ibadan. After further training in clinical immunology in Britain, he returned to Nigeria (1970) to help establish a new medical school at Ahmadu Bello University, Zaria. There he continued his research in malaria and meningococcal disease.

Greenwood spent 15 years directing the UK Medical Research Council Laboratories in The Gambia (1980-95). He helped to establish a multi-disciplinary research program focused on the most prevalent infectious diseases: malaria, pneumonia, measles, meningitis, hepatitis and HIV2. Greenwood demonstrated the efficacy of insecticide-treated bed nets in preventing malaria deaths in children, and demonstrated the impact of Haemophilus influenzae type b and pneumococcal conjugate vaccines in Sub-Saharan Africa.

In 1996 Dr. Greenwood joined the London School of Hygiene & Tropical Medicine where he is now Manson Professor of Clinical Tropical Medicine. He directed the Gates Malaria Partnership (2001-09) and, in 2008, became director of the Malaria Capacity Development Consortium, which supports malaria training-programs in five Sub-Saharan universities. He is also director of a consortium that studies the epidemiology of meningococcal infection in Africa prior to the introduction of a new conjugate vaccine.

Lorne A. Babiuk
OC SOM PHD DSC FRSC
Canada Gairdner Wightman Award
2012
For his extraordinary national and international leadership in vaccine development and research on human and veterinary infectious disease control.
Vice-President (Research), University of Alberta, Edmonton, AB, Canada

The challenge: To reduce the rate of death and disease in humans and animals by building the intellectual and physical infrastructure to create new vaccines that attack infectious diseases.

The work: Dr. Babiuk connected two targets of research usually addressed separately: animals and humans. He identified a vaccine to control diarrhea from rotavirus in calves, which was then developed into a human vaccine. He was also a driving force in developing VIDO, an international vaccine facility in Saskatoon.

Why it matters: One third of all human deaths are caused by infectious disease. About 70% of the new diseases that have emerged in the last 30 years are transmitted from animals to humans. These include Mad Cow Disease, SARS, and the E.coli water contamination in Walkerton, Ontario.

Bio
Lorne A Babiuk received his PhD (1972) from the University of British Columbia. He joined the University of Alberta as Vice-President (Research) in 2007. Prior to moving to the University of Alberta, he spent 34 years at the University of Saskatchewan where he was responsible for building the successful research institution VIDO (Vaccine and Infectious Disease Organization). Under Lorne Babiuk’s leadership, VIDO became internationally recognized as a leader in novel vaccine development. While at VIDO, Babiuk completed its $19.4 million expansion (in 2005) and obtained funding for InterVac, its $140 million level-three biocontainment facility for work on infectious diseases (opened September, 2011).

In addition to being the Vice-President (Research) and former Director of VIDO, Lorne Babiuk has published over 500 peer-reviewed manuscripts and 100 essays and reviews, primarily in virology and immunology. His most recent focus has been on vaccine formulation and delivery. He is a fellow of the Infectious Disease Society of America, the Royal Society of Canada and the European Academy of Sciences as well as an Officer of the Order of Canada.

James C. Hogg
MD PHD
Canada Gairdner Wightman Award
2013
For outstanding leadership in the understanding and treatment of chronic respiratory disease and for a visionary career as a national research builder.
Professor Emeritus, Pathology and Laboratory Medicine, University of British Columbia, BC, Canada

The challenge: According to Health Canada, more than 700,000 Canadians have been diagnosed with Chronic Obstructive Pulmonary Disease (COPD). Thousands more have the disease, but have not been diagnosed. There is currently no cure for COPD.

The work: Dr. Hogg’s early work with the late Dr. Peter Macklem at the Meakins Christie laboratories at McGill University established the small airway in the lung to be the obstruction site in COPD. This work has led to the current concept that this airway is a silent zone where the disease can accumulate over many years, unnoticed by COPD sufferers or their physicians. Dr. Hogg, along with his colleague Dr. Peter Pare, led the establishment of the University of British Columbia Pulmonary Research Laboratory at St. Paul’s Hospital, which now houses more than 200 staff, post graduate, graduate and undergraduate students. His work also led to a collaborative study with Dr. Avrum Spira of Boston University, uncovering a gene expression signature for the emphysematous destruction of the lung in COPD. This research also suggests that the gene expression could be reversed by a small tripeptide found in human blood, paving the way for a potential cure.

Why it matters: Dr. Hogg's research, achieved over a 40 year career, continues to have a fundamental impact on the medical community's knowledge of the pathogenesis, diagnosis and treatment of COPD. Recent results suggest a new direction which could lead to a treatment capable of reversing emphysematous destruction of lung tissue in COPD. Moreover his work stresses the importance of finding a way to diagnose COPD before symptoms appear, allowing for potential prevention of the disease. In addition to his own work, Dr. Hogg has made major contributions to building the Canadian research community locally and nationally. He has also made international contributions in the evaluation of research.

Bio
Dr. Hogg completed his medical degree at the University of Manitoba in 1962, his master's degree in experimental medicine from McGill University in 1967, and his Ph.D. in experimental medicine from McGill University in 1969. Throughout his career, Dr. Hogg's research has remained focused on the mechanisms and anatomical sites of obstructive lung disease. Dr. Hogg's research has advanced the knowledge of how the lung works in health and disease, including the pathophysiology of asthma and the harmful effects of smoking and pollution. In 1977, Dr. Hogg was recruited to the University of British Columbia and St. Paul's Hospital, where he built a world-renowned centre for pulmonary and cardiovascular research, which grew from one trainee each year to approximately 100 each year. This laboratory is currently named The University of British Columbia James Hogg Research Centre for Cardiovascular and Pulmonary Research in his honour. An Officer of the Order of Canada (2005), Dr. Hogg was elected to the Royal Society of Canada (1992) and Canadian Medical Hall of Fame (2010) and has been recognized with an array of scientific awards. In 2003, he was the recipient of the American Society for Investigative Pathology Chugai Award and has been honoured by the American Thoracic Society on several occasions. Dr. Hogg's career work in pathology, pulmonary physiology and molecular biology has leveraged over 40 years of contributions to the world's understanding of lung disease. He has arguably had a greater influence on the medical community's knowledge of Chronic Obstructive Pulmonary Disease and asthma than any other individual worldwide.

MD PHD
John Dirks Canada Gairdner Global Health Award
2013
For global scientific contributions to the field of sexually transmitted disease and their effective treatment and prevention.
William E. Foege Chair of Global Health, Department of Global Health; Center for AIDS & STD, University of Washington, Seattle, WA, USA

The challenge: Sexually transmitted diseases (STDs) and HIV/AIDS are among the leading causes of morbidity and mortality in many developing countries worldwide. In the early 1960s there were approximately six STDs described in textbooks and very little research was happening in sexually transmitted infections. In fact, there were not many medical centers where clinical care was offered for patients with STDs, who were left with few resources.

The work: Dr. Holmes’ career has been dedicated to the study of sexually transmitted diseases. His 45 years of cutting edge research and application of epidemiological, clinical, laboratory, and behavioural science to the study of STDs has expanded the scope of this field tremendously. Numerous clinical trials conducted by Dr. Holmes led to many diagnostic tests and standard-of-care therapies used today to treat and prevent such conditions as human papilloma virus (HPV), gonorrhea, chlamydial infections, and genital herpes, to name a few.

Why it matters: Today, over 35 have been discovered, with Dr. Holmes and his mentees working on approximately 20 of these. Dr. Holmes assisted in defining the causes of many major diseases and through leading numerous clinical trials, has paved the way for many standard-of-care therapies used to treat STDs today.

Bio
Dr. King Holmes is the William H. Foege Chair of Global Health at the University of Washington, a position he has held since 2006. He is also founder and director of the University of Washington Center for AIDS and STD, a World Health Organization Collaborating Center for AIDS and STD. Currently, Dr. Holmes is also the head of Infectious Diseases at Harborview Medical Center. Dr. Holmes completed his undergraduate degree at Harvard College in 1959, his medical degree at Cornell University Medical College in 1963 and received his Ph.D. in Microbiology from the University of Hawaii in 1967. Dr. Holmes has been a member of the University of Washington faculty since 1969, holding educational leadership positions in areas such as medicine, microbiology, epidemiology and global health. He is the principal investigator for the International Training & Education Center on Health (I-TECH), a collaborative program between the University of Washington and the University of California, one of the largest HIV/AIDS training programs in the world. Dr. Holmes also directs the University of Washington/Fred Hutchinson Cancer Research Center’s Center for AIDS Research. He has participated in research on STDs for over 40 years in Africa, Latin America, Southeast Asia, and the Western Pacific. He has authored over 550 peer-reviewed publications and edited 30 books, monographs, and journal supplements.

Sir Gregory Winter
CBE FRS
Canada Gairdner International Award
2013
For the engineering of humanized monoclonal antibodies and their widespread use in medical therapy, particularly for treatment of cancer and immune disorders.
Laboratory of Molecular Biology, Medical Research Council; Master, Trinity College, Cambridge University, Cambridge, UK

The challenge: In nature, antibodies help defend us against infectious agents such as viruses and bacteria, and for more than a century, scientists have tried to turn them against cancer. Although they succeeded in turning mouse antibodies against human cancers, when these antibodies were injected into patients to treat the cancer, they were seen as foreign and rejected by the immune system.

The work: Through his research, Sir Gregory Winter discovered how to create synthetic human antibodies against human targets (such as cancer and inflammatory disease) in a way where they will not be rejected by the immune system.

Why it matters: Sir Gregory Winter’s work in the development of antibodies for therapeutic use has led to the development of modern treatments targeted against many of the most detrimental and widespread diseases including many cancers, infectious diseases and inflammatory conditions including Herceptin, Avastin, and Humira.

Bio
Sir Gregory Winter is a member of the Medical Research Council Laboratory of Molecular Biology (LMB) in Cambridge and until recently, served as its Deputy Director. He is now the Master of Trinity College, Cambridge. Sir Gregory Winter graduated from Cambridge University in 1973, specializing in chemistry and biochemistry. He continued his studies with Cambridge University, receiving his PhD in 1976, specializing in protein and nucleic acid sequencing. Sir Gregory Winter is a pioneer in the science of protein engineering, focusing first on enzymes and then antibodies. At the LMB, he invented techniques to humanize rodent antibodies for use as therapeutics (1986), and later to make fully human antibodies (1989) using combinatorial gene repertoires. His inventions are used in about half of the antibody products on the market, including the humanized antibodies Campath-1H, Herceptin, Avastin, Synagis, and the first human antibody (Humira) to be approved by the U.S. Food and Drug Administration. Sir Winter is also an entrepreneur. He is a founder of Cambridge Antibody Technology (1989) and Domantis (2000). Both of these companies pioneered the use of antibody repertoire technologies to make fully human antibody therapeutics. In 2006, Cambridge Antibody Technology Ltd. was acquired by AstraZeneca PLC and Domantis Ltd. by GlaxoSmithKline PLC in 2006. Most recently, Sir Gregory Winter founded Bicycle Therapeutics Ltd., a biotechnology company dedicated to the development of a new generation of biotherapeutics.

Stephen Joseph Elledge
PHD
Canada Gairdner International Award
2013
For elucidation of the DNA damage response as a signaling network that controls DNA repair and genomic stability with profound implications for cancer and other diseases.
Professor, Department of Genetics, Harvard Medical School, Boston, MA, USA

The challenge: Since 1953 we have known that DNA governs the development and functioning of all known living organisms, but the area of DNA damage remained a mystery.

The work: Dr. Elledge’s research led to the identification and characterization of a signal transduction pathway, also known as the “anti-cancer pathway”, which senses and responds to DNA damage. These pathways are responsible for many things, most importantly detecting when cells have over-multiplied. When this detection occurs, the pathway sends a signal to the cell so it can begin to repair itself. This means that the pathway has the ability to suppress tumor development.

Why it matters: Dr. Elledge’s pioneering work has laid the foundation for our current understanding of DNA damage response and has informed the important field of genome instability. The discovery of signal transduction pathways lead to a new way of thinking about DNA damage. Knowledge about the inner working of this sensory pathway has led to a better understanding of how cancer occurs as well as different ways of treating it.

Bio
Dr. Stephen J. Elledge studied at the University of Illinois as an undergraduate and received his PhD in 1983 at the Massachusetts Institute of Technology (MIT) in Biology. In 1989 he was appointed Assistant Professor in the Biochemistry Department at the Baylor College of Medicine. In 1993 he became an Investigator with Howard Hughes Medical Institute and in 1995 was promoted to Professor. In 2003 he joined the Genetics Department at Harvard Medical School and the Division of Genetics at the Brigham and Women’s Hospital. Currently, Dr. Elledge is the Gregor Mendel Professor of Genetics and Medicine at Harvard Medical School.

Daniel W. Bradley
PHD
Canada Gairdner International Award
2013
For critical contributions to the discovery and isolation of the hepatitis C virus, which has led to the development of new diagnostic and therapeutic agents.
Centre for Disease Control (retired); Infectious Disease Consultant, Atlanta, GA, USA

The challenge: After hepatitis A and B were discovered, a new virus emerged that could not be identified through traditional methods of viral detection. This new virus was frequently transmitted through blood transfusion, possibly leading to serious consequences such as cirrhosis (liver scarring), liver failure and even death.

The work: The combined research of these scientists led to the isolation and discovery of the hepatitis C virus and subsequent, preventative screening tests which have virtually eliminated the spread of the virus through blood-transfusions.

Why it matters: Chronic hepatitis C virus affects approximately 150 million people worldwide and can lead to liver failure, liver cancer and even death. In fact, over 350,000 people, globally, die each year from hepatitis C-related liver diseases. Diagnosis of the hepatitis C virus is now a reality and has led to treatment which can cure most patients. In hepatitis B virus and HIV infections, treatment can only control the virus, whereas in hepatitis C, treatment can eradicate the virus completely.

Bio
After graduating from San Jose State University in 1964, Dr. Bradley was recruited by the U.S. Public Health Service (USPHS) to develop methods to detect a variety of carcinogenic compounds in the atmosphere, a very dangerous task. Upon completion of his service in the USPHS, he went on to earn a Master’s degree in Biochemistry from the University of California and a Doctorate from the University of Arizona. In 1971 he was hired by the Centers for Disease Control (CDC) in Phoenix, Arizona to study whether ascorbic acid had the ability to shorten the course of respiratory virus infections. Finding no such benefit, Dr. Bradley then spent his time working on hepatitis A and B viruses, researching their infectivity in non-human primates. These studies were conducted between 1972 and 1975 and led to the identification of a new group of hepatitis viruses. In 1975, his laboratory was contacted by a scientist from Hyland Laboratories interested in the possible identification of a virus responsible for non-A, non-B hepatitis in several hemophiliac patients. Further studies conducted in 1970s and 1980s revealed the presence of a flavivirus, which led to the early identification of what is now known as hepatitis C virus (HCV). Although a fragment of the HCV genome was identified in 1987, public announcement of the successful cloning of HCV was not made until 1989.

Harvey J. Alter
MD
Canada Gairdner International Award
2013
For critical contributions to the discovery and isolation of the hepatitis C virus, which has led to the development of new diagnostic and therapeutic agents.
Senior Investigator & Chief, Infectious Diseases Section; Associate Director for Research, Department of Transfusion Medicine, National Institutes of Health, Bethesda, MD USA

The challenge: After hepatitis A and B were discovered, a new virus emerged that could not be identified through traditional methods of viral detection. This new virus was frequently transmitted through blood transfusion, possibly leading to serious consequences such as cirrhosis (liver scarring), liver failure and even death.

The work: The combined research of these scientists led to the isolation and discovery of the hepatitis C virus and subsequent, preventative screening tests which have virtually eliminated the spread of the virus through blood-transfusions.

Why it matters: Chronic hepatitis C virus affects approximately 150 million people worldwide and can lead to liver failure, liver cancer and even death. In fact, over 350,000 people, globally, die each year from hepatitis C-related liver diseases. Diagnosis of the hepatitis C virus is now a reality and has led to treatment which can cure most patients. In hepatitis B virus and HIV infections, treatment can only control the virus, whereas in hepatitis C, treatment can eradicate the virus completely.

Bio
Dr. Harvey Alter earned his medical degree at the University of Rochester Medical School, and trained in internal medicine at Strong Memorial Hospital and at the University of Washington Hospital in Seattle. In 1961, he came to the National Institutes of Health (NIH) as a clinical associate. He then spent several years at Georgetown University, returning to NIH in 1969 to join the Clinical Center's Department of Transfusion Medicine as a senior investigator, later becoming Chief of Clinical Studies and Associate Director of Research in the Department of Transfusion Medicine at the NIH Clinical Center. Dr. Alter co-discovered the Australia antigen, a key to detecting hepatitis B virus. Later, Dr. Alter spearheaded a project at the Clinical Center that created a storehouse of blood samples used to uncover the causes and reduce the risk of transfusion-associated hepatitis. He was principal investigator on studies that identified non-A, non-B hepatitis, now called hepatitis C. His work was instrumental in providing the scientific basis for instituting blood donor screening programs that have decreased the incidence of transfusion-transmitted hepatitis to near zero. Dr. Alter was also awarded the Clinical Lasker Award in 2000. In 2002, he became the first Clinical Center scientist elected to the National Academy of Sciences (NAS). That same year, Dr. Alter was also elected to the Institute of Medicine.

Salim Yusuf
MBBS DPHIL FRCP(UK) FRCPC FACC FRSC OC
Canada Gairdner Wightman Award
2014
For his exceptional leadership in global clinical trials and population studies of cardiovascular disease that shaped best guidelines for prevention and treatment.
Professor of Medicine & Executive Director of the Population Health Research Institute, McMaster University; Vice President for Research, Hamilton Health Sciences, Hamilton, ON, Canada

The work: Dr. Yusuf’s epidemiological work in over 60 countries in all the inhabited continents of the world shows the majority of risks of both cardiovascular and cerebrovascular disease are attributable to the same few risk factors. He currently leads the largest ever study revealing the role of societal changes in cardiovascular disease (CVD) among 155,000 people from 700 communities in 22 high, middle and low income countries. Dr. Yusuf led the HOPE Trial that demonstrated that Ramipril (an ACE inhibitor) saved lives, prevented heart attacks and strokes among patients with stable heart disease.

The impact: Dr. Yusuf’s trials (such as SOLVD, HOPE, OASIS, CHARM, ON-TARGET, TRANSCEND, etc.) on the prevention and treatment of CVD and related conditions (such as
4 hypertension and diabetes) have improved the care of patients. His research and insights have produced substantial changes in guidelines for the prevention and treatment of disease. His large trials have led to more effective treatments for acute heart attacks, congestive heart failure, heart rhythm abnormalities and chronic heart disorders. These studies have led to better understanding of the role of societal changes on behaviours and risk factors, and how they lead to CVD. Over the last three decades he has built capacity for clinical and population research across Canada and the world by establishing networks at over 1,500 sites in 85 countries.

Bio
Salim Yusuf’s work over 35 years has substantially influenced prevention and treatment of cardiovascular disease globally. Medically qualified in Bangalore 1976, he received a Rhodes Scholarship and obtained a DPhil from Oxford, during which he (along with Richard Peto and Peter Sleight) initiated the concepts of large, simple trials, and meta-analysis. He coordinated the ISIS trial (which set the structure for future international collaborative work in cardiovascular disease) that demonstrated the value of beta-blockers in myocardial infarction, and sat on steering committees for all subsequent ISIS trials.

In 1984, he moved to the National Institutes of Health, Bethesda, USA, where he was a leader in their SOLVD trial (establishing the value of ACE-inhibitors on LV dysfunction) and DIG trial (clarifying the role of digitalis). In 1992 he moved to McMaster University, where he has established an international program of research in cardiovascular diseases and prevention, culminating in the creation of the Population Health Research Institute, which he founded and heads. His therapeutic trials have established the roles of ACE-inhibitors in CVD prevention (the HOPE study), dual antiplatelet therapies in acute coronary syndromes (the CURE study), and the roles of novel antithrombotics and invasive interventions. The PHRI was recently cited by SCImago as possessing the highest impact of Canadian Centers and the 7th highest impact in the world.

His epidemiologic work in over 60 countries in all the inhabited continents of the world shows the majority of risks of both cardiovascular and cerebrovascular disease are attributable to the same few risk factors. He currently leads the largest ever study revealing the role of societal changes in CVD among 155,000 people from 700 communities in 22 high, middle and low income countries. These studies have led to better understanding of the role of societal changes on behaviours and risk factors, and how they lead to CVD.

Over the last 3 decades he has built capacity for clinical and population research across Canada (first through the Canadian Cardiovascular Collaboration, and more recently through CANNeCTIN) and the world by establishing networks at over 1500 sites in 85 countries, spanning all inhabited continents of the world. He has trained over 50 researchers, many of whom are nationally or internationally renowned leaders in medical research. He has helped develop major research institutes or programs in Canada, India, Argentina, Brazil, S. Africa, Saudi Arabia, Malaysia, and China.

He holds a Heart and Stroke Foundation of Ontario Research Chair, was a Senior Scientist of the Canadian Institutes of Health Research (1999-2004), and has received over 35 international and national awards for research, induction into the Royal Society of Canada, an appointment as an Officer of the Order of Canada, and in 2014 he will be inducted into the Canadian Medical Hall of Fame.

He has published over 800 articles in refereed journals, rising to the second most cited researcher in the world for 2011. He is President-elect of the World Heart Federation, where he is initiating an Emerging Leaders program in 100 countries with the aim of halving the CVD burden globally within a generation.

2014
Array
For the discovery of the microorganism Streptomyces avermitilis and its extraordinary biologic activity that in partnership with Merck led to the identification of avermectin and development of ivermectin, a highly successful treatment for many parasitic diseases, and the global consortium directed at eliminating river blindness.
Distinguished Emeritus Professor; Special Coordinator, Drug Discovery from Natural Products, Kitasato University, Tokyo, Japan

The work: In 1973, the Kitasato Institute in Japan, led by Professor Satoshi Omura, formed a collaborative research partnership with Merck to discover new animal health products. Within this partnership, Professor Omura and his research team based at the Kitasato Institute in Tokyo isolated and screened microorganisms and sent the promising ones to the Merck laboratories in the United States. Of particular interest was a microorganism, Streptomyces avermitilis, isolated from soil near an oceanside golf course in Japan which had potent bioactivity. Researchers at Merck’s lab conducted further testing on the microorganism and then the compound responsible for the activity was named avermectin. Scientists at Merck refined avermectin under the name ivermectin, which was the safest and most potent derivative. Despite decades of searching around the world, the Japanese microorganism remains the only source of avermectin ever found.

The impact: Ivermectin, commercialized in 1981 as a highly successful veterinary drug active against both internal and external parasites, was later found to be safe and effective for treating several human parasitic diseases such as Onchocerciasis (river blindness) and Lymphatic filariasis (elephantiasis). Merck joined forces with the World Health Organization (WHO), the Special Programme for Research and Training in Tropical Diseases (TDR) and the Onchocerciasis Control Programme in West Africa (OCP) to test the drug in humans. Ivermectin was registered for human use by French regulators in 1987. With the Kitasato Institute agreeing to forego royalties, Dr. Roy Vagelos, the then Chief Executive of Merck, announced that ivermectin would be provided free of charge for the treatment of river blindness for “as long as it is needed,” a pledge that is still being honoured. Utilizing a truly international partnership involving the public and private sectors, governments of disease-endemic countries and affected communities, mass drug administration commenced in 1988 and the donation has allowed the goal of eliminating both diseases to become achievable in the near future. Ivermectin has also become the drug of choice to treat strongyloidiasis, scabies and head lice and research is being conducted into its effectiveness against other neglected tropical diseases.

Bio
Prof. Satoshi Ōmura received an M.S. degree in 1963 from Tokyo University of Science, followed by a Ph.D. in Pharmaceutical Sciences in 1968 from the University of Tokyo, and another in Chemistry two years later from the Tokyo University of Science. His first position was as a Research Associate at University of Yamanashi (1963-1965). In 1965 he began his career-long association with the Kitasato Institute, initially as a researcher, over the years occupying various posts, culminating in his appointment in 1990 as President. He served as President Emeritus of The Kitasato Institute (2008-2012), and is currently a Distinguished Emeritus Professor and Special Coordinator of the Research Project for Drug Discovery from Natural Products in the Kitasato Institute for Life Sciences, Kitasato University. He was also appointed as inaugural Max Tishler Professor of Chemistry at Wesleyan University (USA) in 2005.

Commencing with his studies in Organic Chemistry at the Tokyo University of Science, from 1965 onwards he has performed comprehensive research on Bioorganic Chemistry, focusing on bioactive substances of microbial origin. He devised several innovative new methods for isolating and culturing microorganisms and established many original methods of screening for bioactive substances. As a result, he has discovered more than 470 novel bioactive compounds. Among them, the globally significant anthelmintic antibiotic avermectin and its derivatives, seen by many to rival penicillin in their impact on global health, were discovered through collaborative research with Merck Sharp & Dohme Research Laboratories (USA), his group eventually deciphering the entire genome of the producing organism, Streptomyces avermectinius.

Prof. Ōmura has been widely recognized in the natural-products chemistry field, as evidenced by his numerous awards and honors. Among these are the Hoechst-Roussel Award from American Society for Microbiology, Charles Thom Award (Society for Industrial Microbiology, USA), Robert Koch Gold Medal (Germany), Prince Mahidol Award (Thailand), Nakanishi Prize of Japan Chemical Society and the American Chemical Society, Ernest Gunther Award of the American Chemical Society, Hamao Umezawa Memorial Award of the International Society of Chemotherapy, Tetrahedron Prize for Creativity in Organic Chemistry, Arima Award of the International Union of Microbiology, and the Japan Academy Prize. He has been decorated with France’s L’Ordre National de la Legion d’Honneur Chevalier in 2007, and also has been designated by Japan in 2012 as a highly-prestigious Person of Cultural Merit.

For her discovery of the mechanisms by which mammalian telomeres are protected from deleterious DNA repair and damage responses.
Leon Hess Professor; Director, Anderson Centre for Cancer Research, Rockefeller University, New York, NY, USA

The work: The problem de Lange has focused on for the past two decades is a basic problem in cell biology. Chromosomes are made of protein and a single molecule of deoxyribonucleic acid (DNA) and have two ends. Our body has a vigilant surveillance system which is always looking for damage to our DNA, including breaks which can lead to various diseases, such as cancer. The ends of chromosomes are called telomeres and Dr. de Lange discovered that they are bound by a complex of proteins she named shelterin. De Lange’s work addressed the mechanism by which telomeres protect chromosome ends, an issue she refers to as the “telomere end-protection problem.” De Lange revealed that telomeres need to repress six distinct DNA damage response (DDR) pathways that threaten genome integrity. She identified the shelterin protein complex that protects telomeres and established how distinct shelterin subunits repress different DDR pathways.

The impact: Her work has solved a long-standing riddle in biology, one that has profound implications for our understanding of effective cell proliferation, chromosome integrity and a diverse array of human disorders including cancer and aging. The work on the telomere end- protection problem and the types of genome instability that result from lack of telomere function has informed scientists about the events involved in early tumorigenesis when telomeres shorten due to the lack of telomerase. De Lange’s findings argue that the genome instability in human cancer is in part due to loss of telomere function. Furthermore, understanding how telomeres solve the end-protection problem is directly relevant to the telomeropathies, which are diseases caused by compromised telomere function.

Bio
Titia de Lange received training in biochemistry at the University of Amsterdam and the Dutch Cancer Institute. As part of her undergraduate training, she worked on globin gene expression with Richard Flavell at the NIMR in Mill Hill before joining Piet Borst in 1981 at the Dutch Cancer Institute as a graduate student. In 1985, she obtained her PhD (cum laude) and joined Harold Varmus at UCSF for postdoctoral studies. With Varmus, she isolated human telomeric DNA and was the first to show that tumor telomeres shorten. In 1990, she was appointed as Assistant Professor at the Rockefeller University where she was promoted to Professor in 1997. She currently is the Leon Hess Professor, an American Cancer Society Research Professor, and the Director of the Anderson Cancer Center at the Rockefeller University. De Lange is a (foreign) member of EMBO, the US National Academy of Science, the Dutch Royal Academy of Sciences, the American Academy of Arts and Science, the American Association for Advancement of Science, the American Society for Microbiology, the New York Academy of Science, and the Institute of Medicine. De Lange was awarded the inaugural Paul Marks Prize for Cancer Research, the Massachusetts General Hospital Cancer Center Prize, the AACR’s Charlotte Friend and G.H.A. Clowes Awards, the Vilcek Prize, the Vanderbilt Prize, the Dr. H.P. Heineken Prize, and the Breakthrough Prize in Life Sciences. She holds an honorary degree from the University of Utrecht. De Lange has served on the scientific advisory boards of many US and European academic institutions, including MSKCC, CSHL, the MIT Cancer Center, the IMP in Vienna, the CRUK/LRI in London, and the Ludwig Institute for Cancer Research. De Lange also serves on several award committees, including the Lasker Jury, the Vilcek Prize selection committee, and the Pearl Meister Greengard Prize committee.

James Allison
PHD
Canada Gairdner International Award
2014
For his discovery of immune checkpoint blockade and its successful application to immune therapy of cancer.
Professor and Chair, Department of Immunology, University of Texas MD Anderson Cancer Center, Houston, TX, USA

The work: Allison’s research has focused on T cell biology. T cells are white blood cells that scan our bodies for cellular abnormalities and infections. Allison’s work discovered the receptor these cells use to recognize and bind to antigens for attack. Immunologists have long wondered why the immune system doesn’t fight off cancer cells itself and Allison discovered the first ‘blocker’ that blocks the immune system from doing so. This discovery was the immune checkpoint molecule called CTLA-4, which turns off T cells before they can respond to tumors they’ve been set to destroy. Allison developed an antibody to block CTLA-4, freeing T cells to attack tumors, and leading to the development of the drug ipilimumab. The U.S. Food and Drug Administration (FDA) approved ipilimumab (Yervoy®) for treatment of metastatic melanoma in 2011.

The impact: Allison’s concept has opened a new field of cancer therapy, immune checkpoint blockade, and many cancer patients are alive today because of his vision. Immune checkpoint blockade treats the immune system instead of the tumor which provides the option to work across other cancers. In addition to melanoma, ipilimumab has been effective in clinical trials against prostate, kidney, lung and ovarian cancers.

Bio
Dr. Allison is a professor and chair of the Department of Immunology, executive director of the Immunotherapy Platform and deputy director of the David H. Koch Center for Applied Research of Genitourinary Cancers at The University of Texas MD Anderson Cancer Center. A recent addition to MD Anderson in November 2012, Dr. Allison is building a team of clinicians and physician-scientists to accelerate the movement of immune-based combinatorial therapies into clinical trials. Since joining us, he has already received funding from Stand Up to Cancer and the Cancer Research Institute (SU2C/CRI) to lead a Dream Team in Translational Immunology Research with the aim of facilitating clinical development of new and improved forms of cancer immunotherapy.

Dr. Allison received a B.S. in microbiology and a Ph.D. in biological sciences from the University of Texas at Austin, then completed a postdoctoral fellowship in the Department of Molecular Immunology at the Scripps Clinic and Research Foundation in California. He began his academic career as an assistant professor in the Department of Biochemistry at the University of Texas, Science Park–Research Division in Smithville, Texas, and quickly achieved the rank of professor in the Department of Molecular and Cellular Biology, Division of Immunology at the University of California, Berkeley. Dr. Allison was recruited to MD Anderson from Memorial Sloan-Kettering Cancer Center, where he had been the chair of the Immunology Program, the attending immunologist and director of the Ludwig Center for Cancer Immunotherapy, and a professor at the Weill Medical College of Cornell University since 2004.

Dr. Allison has more than 260 publications, including articles in Nature, Science, Cell, Immunity, Cancer Cell and Blood. He has received numerous awards in recognition of his seminal work, including the Dana Foundation Award in Human Immunology Research (2008), the Richard V. Smalley, M.D. Memorial Lectureship Award (2010), a Lifetime Achievement Award from the American Association of Immunologists (2011), the Roche Award for Cancer Immunology and Immunotherapy (2011), the Novartis Prize for Clinical Immunology (2013), and the Breakthrough Prize in Life Sciences (2013).

Canada Gairdner International Award
2014
For the discovery of anti-TNF therapy for the treatment of rheumatoid arthritis and other inflammatory diseases.
Visiting Professor Kennedy Institute of Rheumatology, University of Oxford, Oxford, UK

The work: Rheumatoid arthritis (RA) is a common, chronic, painful and disabling autoimmune disease. Prior to the work of Drs. Feldmann and Maini, the treatment of RA was not based on understanding of which molecules were produced in excess. In the mid-1980’s, the team began work on unravelling which molecules might be the culprit of this disease in hopes of determining which targets would be ideal for treatment. Experiments in the laboratory on cells from joints of patients and in an animal model of RA demonstrated that tumor necrosis factor (TNF), a molecule belonging to the ‘cytokine’ family, was a major driver of inflammation and joint damage. They discovered a monoclonal antibody-based treatment that blocked the action of TNF and was safe and effective for treating in RA. Anti-TNF therapy works in most patients rapidly to reduce pain, improve mobility, reduce work disability, improve social functioning, and, when compared with patients on conventional synthetic drug treatments, reduces the risk of heart attacks, strokes and increases life expectancy. It has a major role in protecting joints from degeneration, thus maintaining good physical function and reducing the need for joint surgery.

The impact: They discovered the first treatment for RA, using monoclonal antibodies which are genetically engineered natural defense molecules. Not only was this a novel treatment, but it was the first demonstration of the efficacy of a biological therapy for a chronic autoimmune disease and led to the recognition by the pharmaceutical industry that biological drugs are a viable class of therapeutic agents that can compete with traditional chemical drugs. The effective results have not only transformed the treatment for patients, but have led to other successful anti-TNF treatments, and encouraged much further work using antibodies for treatment.

Bio
Sir Ravinder Maini, born to Indian parents, received his early school education in Uganda and has resided permanently in the UK since 1955. After high school in London, he studied medicine at Cambridge University and Guy's Hospital; London (qualified BA MB BChir 1962). He undertook his postgraduate clinical training and a Fellowship in clinical immunology. Throughout his professional career since 1970 he has combined practice as a Clinician-Scientist in rheumatology and internal medicine with laboratory-based immunological research. From 1990 to 2002 he was Professor and Scientific Director/Head of The Kennedy Institute of Rheumatology, London.

His research has focussed on immunological and inflammatory mechanisms and therapy of autoimmune rheumatic diseases. His ‘bench to bedside’ research, in collaboration with Marc Feldmann which commenced in 1985, resulted in the development of anti-TNF immunotherapy of rheumatoid arthritis. He has been invited as a keynote speaker at International scientific meetings; published over 480 papers in scientific journals; served on the Editorial Board of immunology and rheumatology journals; and is currently Co-Editor in Chief of the open access journal 'Arthritis Research and Therapy'.

Since retirement, he is a Visiting Professor to the Kennedy Institute of Rheumatology at Oxford. He continues to serve as a Consultant and Advisor to the Biotechnology and Pharmaceutical industry and National Grant-Giving Agencies. He serves as a Trustee of Medical Charities, currently a Trustee and President of the Kennedy Trust for Rheumatology Research, UK, and Trustee of The Sir Jules Thorn Trust.

His research contributions have been recognised the awards of a Knighthood (2003) by HM Queen Elizabeth; election to learned scientific societies: he is a Fellow of Royal Society, London (FRS), Fellow of the Academy of Medical Sciences (FMedSci), Foreign Associate Member of the USA Academy of Sciences, Fellow of the Royal Colleges of London and Edinburgh and Honorary Fellow of Sidney Sussex College, Cambridge; honorary Doctorates of the Universities of Glasgow and University Rene Descartes, Paris; Distinguished Investigator Award by the American College of Rheumatology; and Honorary Fellowships of Scientific Societies in the United Kingdom, Europe and Australia.

Following the identification of TNF as a therapeutic target and translation of anti-TNF therapy to the clinic, Professors Maini and Feldmann have been jointly awarded many prizes, notably the Crafoord Prize by The Royal Swedish Academy of Sciences, The Lasker prize for Clinical Research, Dr Paul Jannsen Award for Biomedical Research, Ernst Schering Prize and in 2014, they have been selected as recipients of the Canada Gairdner International Award.

The effective results have not only transformed the treatment for patients, but have led to other successful anti-TNF treatments, and encouraged much further work using antibodies for treatment.

Bio
After training in medicine and realising that research was the path towards improving therapy, he studied for a PhD in immunology at the Walter and Eliza Hall Institute in Melbourne with Prof. Sir Gus Nossal. There he learnt to optimise immune responses in tissue culture, and also studied potent intercellular mediators, molecules later identified as cytokines, autoimmunity and immuneregulation.

In 1983, while working in Av Mitchison’s ICRF Tumour Immunology Unit at University College London, on reflecting about the new observations of upregulated MHC class II in local sites of autoimmunity (e.g. thyroid) he proposed that this reflected augmented antigen presentation. Since cytokines, especially interferons upregulate MHC antigens, in 1983 he published a hypothesis that upregulated cytokines and antigen presentation were key steps in the generation of a chronic autoimmune disease. This was a testable hypothesis, and was successfully tested on Grave’s thyroiditis by 1985-6. This led to collaboration with Ravinder Maini, relocation to the Kennedy Institute, and the exploration of what were critical cytokines in the most accessible human autoimmune disease, rheumatoid arthritis. New methods were developed to assess which cytokines were produced locally demonstrating that many pro-inflammatory cytokines were produced. To unravel which was the best target, he analysed cytokine regulation in dissociated rheumatoid arthritis synovial tissue, and found that blockade of TNF also downregulated IL-1 and other pro-inflammatory cytokines, indicating that TNF was the long sought after therapeutic target. This was validated in mouse arthritis, treatment given after disease onset. Thus there was a rationale for a proof-of-principle clinical trial of anti-TNF, and he was a leader with my colleague Prof. Sir Ravinder Maini of this and subsequent clinical trials which led to approval for anti-TNF therapy in rheumatoid arthritis. This success and that of other anti-TNF antibodies has made anti-TNF the best-selling drug class from 2012. He succeeded Ravinder Maini as Director of Kennedy Institute in 2002.

This work has led to his election to various national academies of science (e.g. Royal Society, Australian Academy of Science and the National Academy of Science, USA), and multiple prestigious prizes, mostly with his colleague Sir Ravinder Maini, e.g. Crafoord Prize of Royal Swedish Academy, the Albert Lasker Clinical Medical Research Award, Ernst Schering Prize, Paul Janssen prize.

For discovering Vascular Endothelial Growth Factor (VEGF), a key molecular mediator of new blood vessel formation and the development of effective anti-VEGF. therapy for cancer and wet macular degeneration
Distinguished Professor of Pathology; Senior Deputy Director for Basic Sciences, University of California San Diego Moores Cancer Center, San Diego, CA, USA

The work: Blood vessels are the part of the circulatory system that transports blood throughout the body and also play a vital role in virtually every medical condition. In 1983, Dr. Dvorak reported a tumour-derived protein that caused the cells lining tumor blood vessels to become leaky (hyperpermeable) to circulating molecules. He called the protein vascular permeability factor (VPF). Subsequently, he demonstrated that VPF was also secreted by many normal cells and plays a key role in wound healing and chronic inflammatory diseases. At the same time, Dr. Ferrara noted that cells released a factor that caused cells to divide. This factor stimulated the production of new blood vessels from pre-existing vessels (angiogenesis). In 1989, Dr. Ferrara reported for the first time the isolation and sequencing of vascular endothelial growth factor (VEGF) which, after testing, ended up being the exact same molecule as VPF, and VEGF became its new name.

The impact: Dr. Dvorak’s research demonstrated that most malignant tumors make VEGF, which assists the tumors to grow beyond minimal size by forming new blood vessels and connective tissue support as in wound healing. Dr. Ferrara’s cloning and characterization of VEGF enabled progress in this field. In addition, Dr. Ferrara and his team made key advances in understanding how VEGF was made, how it acted and its role. Importantly, Dr. Ferrara and his colleagues pioneered the clinical development of an inhibiting antibody against VEGF which opened up a new era of cancer therapy because this new approach focused on choking off the blood supply that tumours need in order to grow and spread. These findings also spearheaded the development of an anti-VEGF antibody fragment (ranibizumab) which has shown dramatic efficacy in maintaining and improving vision in wet age-related macular degeneration (AMD) patients.

Bio
Dr. Ferrara earned his M.D. degree in 1981 from the University of Catania Medical School in Italy. After completing his postdoctoral research at the University of California, San Francisco, he joined Genentech Inc. in 1988. It is there where he spent nearly 25 years working on the molecular characterization and therapeutic applications of VEGF-A, which resulted in the development of bevacizumab, the first anti-angiogenic agent to be approved by the FDA for cancer therapy. His research also led to the development of ranibizumab, which has been FDA-approved for the treatment of multiple intraocular neovascular disorders. In January 2013, Dr. Ferrara joined the University of California, San Diego as a Distinguished Professor of Pathology, Distinguished Adjunct Professor of Ophthalmology and Senior Deputy Director for Basic Sciences of the Moores Cancer Center.

Dr. Ferrara has authored over 300 scientific publications. He is also the recipient of numerous awards including the Lefoulon-Delalande-Institut-de-France Prize, the Passano Award, the General Motors Cancer Research Award, the ASCO Science of Oncology Award, the Pezcoller Foundation-AACR International Award, the Lasker-deBakey Clinical Medical Research Award, the Dr. Paul Janssen Award, the Economist Innovation Award and the inaugural Breakthrough Prize in Life Sciences. Dr. Ferrara has been a member of the National Academy of Sciences, USA, since 2006.

These findings also spearheaded the development of an anti-VEGF antibody fragment (ranibizumab) which has shown dramatic efficacy in maintaining and improving vision in wet age-related macular degeneration (AMD) patients.

Bio
Dr. Harold F. Dvorak is the founding Director of the Center for Vascular Biology Research (CVBR) at the Beth Israel Deaconess Medical Center (BIDMC) and the Mallinckrodt Distinguished Professor of Pathology at Harvard Medical School. In 1983, Dr. Dvorak and his colleagues were the first to demonstrate that tumor cells secreted vascular endothelial growth factor (VEGF), known at the time as vascular permeability factor or VPF. This seminal discovery provided the molecular basis for the field of angiogenesis. Dr. Dvorak went on to make the critically important observation that tumors behave like “wounds that do not heal” in that the vascular and stromal responses they induce closely mimic those of healing wounds. More recently, his work has characterized the different types of blood vessels that tumors generate and the molecular mechanisms by which they form.

Dr. Dvorak has taught for many years at the Harvard Medical School, and has lectured frequently as a visiting professor and at numerous national and international scientific conferences. He is a fellow of the American Association for the Advancement of Science and of the National Foundation for Cancer Research and has served as President of the American Society for Investigative Pathology which awarded him the 2002 Rous-Whipple award, and, forthcoming in 2013, the Gold-headed cane award for his scientific accomplishments. In 2005 he received the Grand Prix Lefoulon-Delalande from the Institut de France and in 2006 the inaugural Albert Szent-Gyorgyi Prize for Progress in Cancer Research from the National Foundation for Cancer Research (NFCR). Educated at Princeton University and Harvard Medical School, he did a Pathology residency at the Massachusetts General Hospital and postdoctoral research at the National Institutes of Health. He has served on the Harvard Medical School faculty since 1967 and at BIDMC since 1979. After stepping down after 26 years as Chair of Pathology at BIDMC in July 2005, Dr. Dvorak focused his efforts on building the CVBR, while at the same time continuing to pursue his research.

Shimon Sakaguchi
MD PHD
Canada Gairdner International Award
2015
For his discovery of regulatory T cells, characterization of their role in immunity and application to the treatment of autoimmune diseases and cancer.
Distinguished Professor, World Premier International Research Initiative (WPI)-Immunology Frontier Research Center (IFReC), Osaka University, Osake, Japan

The work: To stay healthy our immune system needs to discriminate between itself and invaders (non-self). When unable to differentiate between the two, the immune system destroys healthy cells or tissues causing autoimmune diseases. Dr. Sakaguchi discovered regulatory T (Treg) cells which help maintain order in the immune system and act as a ‘self-check’ to prevent excessive reactions as without Treg cells the body would attack the healthy cells and die. He was the first to determine their molecular basis and function.

The impact: Within his laboratory, Dr. Sakaguchi demonstrated that increasing the number of Treg cells can prevent and treat autoimmune diseases. Further, Treg cells suppress the immune system against cancer and there are now several clinical trials within this area.

For his co-discovery of the Ebola virus, his many contributions to HIV/AIDS research and his extraordinary leadership in the global response to the HIV/AIDS epidemic, especially in Africa.
Director, London School of Hygiene & Tropical Medicine, London, UK

The work: Dr. Piot is a co-discoverer of the Ebola virus and its modes of transmission and its epidemiology. His pioneering work on HIV/AIDS in Africa revealed a major heterosexual HIV epidemic, established much of the knowledge of the clinical manifestations, natural history and epidemiology of HIV in Africa, including the first studies showing the effectiveness of HIV prevention in high risk populations. He also identified several original risk determinants for HIV transmission. His team was the first to document the association between tuberculosis (TB) and HIV in Africa, and the wide genetic diversity of HIV-1 in Africa, as well as a related immunodeficiency virus in chimpanzees.

The impact: Dr. Piot played a leading role in bringing the AIDS epidemic to the forefront of global attention, raising international commitments to its funding and building scientifically grounded responses to its control and treatment. His team’s work on the strong association of tuberculosis and HIV in Africa, followed by clinical and therapeutic studies, led to new guidelines for managing tuberculosis in Africa. His studies on the prevention of HIV infection among high risk populations were again among the first in Africa, and demonstrated that such prevention is possible.

Canada Gairdner International Award
2015
Array
For pioneering the molecular elucidation of autophagy, an essential intracellular, degradation system and when disordered, is linked to many diseases including neurodegeneration, cancer, and infection.
Professor, Institute of Innovative Research, Tokyo Institute of Technology, Tokyo, Japan

The work: He was the first person to visually observe the function of autophagy (self-eating), whereby cells clean up the garbage within them by killing invaders and keeping healthy cells. It works as a cell recycling system to maintain homeostasis within the body. He then clarified the mechanism of autophagy and the genes involved.

The impact: Autophagy is now regarded as a vital cell-recycling system and may aid in future developments to treat neurodegenerative diseases such as Alzheimer’s, cancer and other age- related diseases. Dr. Ohsumi’s research findings have since been applied to autophagy in animals as well, and many researchers are now working to further clarify the molecular mechanism and physiological significance of this process.

Bio
Dr. Yoshinori Ohsumi was born in Fukuoka in 1945. In 1963, he entered to The Univ. of Tokyo, then he chose decisively to follow molecular biology as the path of his future. As a graduate student, Dr. Ohsumi studied the initiation mechanism of E. coli ribosome and then action of colicin E3, which inhibits the translation of E. coli cells by binding to its receptor. Near the end of 1974, he enrolled in Rockefeller Univ., to study under Dr. G. M. Edelman. First Dr. Ohsumi worked on in vitro fertilization in mice, then switched to work on the mechanism of initiation of DNA replication using yeast, which introduced him to yeast research. Dr. Ohsumi returned to Japan at the end of 1977, and worked as an assistant professor under Prof. Y. Anraku, at the Faculty of Science, The Univ. of Tokyo. Dr. Ohsumi decided to take up the study of the yeast vacuolar membrane. By making pure vacuolar membrane vesicles, he succeeded to show various active transport systems and a novel type of proton-pump, v-type ATPase on the vacuolar membrane. In 1988, Dr. Ohsumi became an associate professor in College of Arts and Sciences of The Univ. of Tokyo and opened up his own small lab. He decided to work on the lytic function of the vacuole. Soon after, Dr. Ohsumi found yeast autophagy by light and electron microscopy. Taking advantage of yeast system, he performed a genetic screen for autophagy-defective mutants. His group could get 15 genes essential for starvation-induced autophagy by the first screen, and started cloning of these ATG genes. Then Dr. Ohsumi moved to The National Inst. for Basic Biology at Okazaki, and uncovered that these Atg proteins consist of six unique functional groups, such as a protein kinase complex, two ubiquitin-like conjugation systems, a PtdIns 3-kinase complex and so on. Drs. T. Yoshimori and N. Mizushima in his lab started studies on ATG genes in mammals and a student also worked on plant, proving that the ATG system is well conserved in higher eukaryotes. However, up to now, Dr. Ohsumi has focused on dissection of the molecular mechanism of the Atg proteins in yeast. In 2009, Dr. Ohsumi moved to Tokyo Inst. of Technology, and continues to elucidate the molecular details of membrane dynamics during autophagosome formation and the physiological relevance of autophagy by combination of cell biology, biochemistry, molecular biology, and structural biology.

Lynne E. Maquat
PHD
Canada Gairdner International Award
2015
For the discovery of the mechanism that destroys mutant messenger RNAs in human cells, nonsense-mediated mRNA decay, which is critically important in both normal and disease states.
J. Lowell Orbison Endowed Chair; Professor of Biochemistry & Biophysics; Professor of Oncology, School of Medicine and Dentistry; Director, Center for RNA Biology: From Genome to Therapeutics; Chair of Graduate Women in Science, University of Rochester, Rochester, NY, USA

The work: Messenger RNA (mRNA) takes genetic instructions from DNA and uses them to create proteins that carry out multiple cellular functions. Dr. Maquat discovered nonsense- mediated mRNA decay (NMD) in human cells. NMD is a quality control mechanism that removes flawed messenger RNA molecules that, if left intact, would lead to the production of abnormal proteins that could be toxic to cells and initiate disease. Cells also use this pathway to better respond to changing environmental conditions. For example, breast cancer cells inhibit this pathway to augment their response to chemotherapy and hasten cell death.

The impact: Nonsense-mediated mRNA decay functions in one-third of inherited disorders, such as cystic fibrosis, and one-third of acquired diseases, including many forms of cancer. Her work has furthered our understanding of the molecular basis of human disease and provides valuable information to help physicians implement “personalized” or “precision” medicine by treating the disease mutation that is specific to each individual patient.

Bio
Lynne E. Maquat holds the J. Lowell Orbison Endowed Chair and is Professor of Biochemistry & Biophysics and Professor of Oncology in the School of Medicine and Dentistry, Director of the Center for RNA Biology: From Genome to Therapeutics, and Chair of Graduate Women in Science at the University of Rochester in Rochester, New York, USA. After obtaining her PhD from the University of Wisconsin-Madison and post-doctoral work at the McArdle Laboratory for Cancer Research in Madison, she joined the Roswell Park Cancer Institute in Buffalo before moving her laboratory to the University of Rochester. Professor Maquat is known for her mammalian-cells studies of nonsense-mediated messenger RNA decay, which she first reported in 1981 through studies of the hemolytic anemia bo-thalassemia and from which she subsequently discovered the pioneer round of translation, the exon-junction complex (EJC), and how the EJC marks mRNAs for a first quality-control translation cycle that largely occurs as newly synthesized messenger RNAs enter the cytoplasm. She continues to make seminal contributions on mechanisms of NMD and another pathway she discovered and named Staufen-mediated mRNA decay (SMD). Her work on SMD has defined new roles for long non-coding RNAs and small interspersed elements in humans and rodents, unveiling the complexities of RNA-RNA interactions that comprise important post-transcriptional gene regulatory pathways during mammalian-cell development and differentiation. Professor Maquat has served on editorial boards including RNA, Mol. Cell Biol., RNA Biol., and Methods, as an elected Director, Treasurer/Secretary and President of the RNA Society, as a member of the Public Information Committee of the American Society for Cell Biology, and as chair of NIH study section. She is an elected Fellow of the American Association for the Advancement of Science (2006), an elected Member of the American Academy of Arts and Sciences (2006) and the National Academy of Sciences (2011), and a Batsheva de Rothschild Fellow of the Israel Academy of Sciences and Humanities (2012). Professor Maquat was awarded the William C. Rose Award from the American Society for Biochemistry and Molecular Biology (2014) for research and mentoring, in particular advocacy for women in science.

Michael N. Hall
PHD
Canada Gairdner International Award
2015
For his discovery of the nutrient activated protein kinase TOR and elucidation of its central control of cell growth, critical to development and aging and widely implicated in cancers, diabetes, cardiovascular and immune diseases.
Professor, Biozentrum, University of Basel, Basel, Switzerland

The work: Cell division, growth and death are the most fundamental features of life. Dr. Hall discovered and named the protein “target of rapamycin” (TOR), which regulates cell growth. In TOR, Hall found a key protein in cellular communication that when blocked pharmacologically can contain the uncontrolled cell growth and division that is typical for cancer. TOR is also a central controller of cell growth that plays a key role in development and TOR was the first protein that demonstrated to influence longevity in all of the four ageing species that scientists commonly use to study ageing: yeast, worms, flies and mice.

The impact: Dr. Hall's discovery has contributed to a deeper understanding of fundamental life processes such as cell division, growth and death. Insights into TOR signaling pathways and their involvement in disease have opened the door for new therapeutic strategies for cancer, obesity, diabetes, and cardiovascular disease. Pharmacological inhibition of TOR also helps patients accept transplanted organs.

Bio
Michael N. Hall was born (1953) in Puerto Rico and grew up in South America (Venezuela and Peru). He received his Ph.D. from Harvard University and was a postdoctoral fellow at the Pasteur Institute (Paris, France) and the University of California, San Francisco. He joined the Biozentrum of the University of Basel (Switzerland) in 1987 where he is currently Professor and former Chair of Biochemistry. Hall is a pioneer in the fields of TOR signaling and cell growth control. In 1991, Hall and colleagues discovered TOR (Target of Rapamycin) and subsequently elucidated its role as a central controller of cell growth and metabolism. TOR is a conserved, nutrient- and insulin-activated protein kinase. The discovery of TOR led to a fundamental change in how one thinks of cell growth. It is not a spontaneous process that just happens when building blocks (nutrients) are available, but rather a highly regulated, plastic process controlled by TOR-dependent signaling pathways. As a central controller of cell growth and metabolism, TOR plays a key role in development and aging, and is implicated in disorders such as cancer, cardiovascular disease, diabetes, and obesity. Hall is a member of the US National Academy of Sciences, has received numerous awards, including the Cloëtta Prize for Biomedical Research (2003), the Louis-Jeantet Prize for Medicine (2009), the Marcel Benoist Prize for Sciences or Humanities (2012), and the Breakthrough Prize in Life Sciences (2014), and has served on several editorial and scientific advisory boards. He and his wife Sabine (née Carrère) live in Basel with their daughters Zoé and Léa.

Frank Plummer
Canada Gairdner Wightman Award
2016
For his groundbreaking research in Africa in understanding HIV transmission and his leadership at the Canadian National Microbiology Laboratory with pivotal roles in SARS, influenza and Ebola epidemics.
Special Advisor to the Chief Public Health Officer, Public Health Agency of Canada; Distinguished Professor, Medical Microbiology, College of Medicine, Faculty of Health Sciences, University of Manitoba, Winnipeg, MB, Canada

The work: In the 1980s, HIV/AIDS was largely viewed as a homosexual disease. Throughout the 1980s, Dr. Frank Plummer conducted research, facilitated by the University of Manitoba, on a large cohort of Nairobi sex workers which found that two thirds of them had HIV/AIDS which was astonishing at the time. He also showed that about ten percent of these sex workers remain HIV uninfected despite multiple exposures. This identification of natural resistance to HIV has guided vaccine development strategies. He further went on to conduct work on mechanisms of resistance to HIV, risk factors for heterosexual transmission of HIV, mother-to-child transmission of HIV and developed public health strategies for control of sexually transmitted infections. Further research showed that many groups in addition to these female sex workers are immune to HIV. Over the next 16 years, Dr. Plummer remained in Nairobi, and this led to a series of investigations, international collaborations and some very important discoveries about the susceptibility to HIV infection and transmissibility.

The impact: His original and sustained contributions in this field have led to innovative strategies for HIV prevention at an internationally recognized level, and are being used around the world to prevent many thousands of HIV infections. Dr. Plummer, Distinguished Professor, University of Manitoba, is a pioneering HIV/AIDS researcher thanks to not only his ground-breaking work but also his leadership as Scientific Director General at the National Microbiology Laboratory in Winnipeg leading their response to numerous outbreaks including his support and contributions to the development of the Ebola vaccine programs in Canada, SARS treatment in 2003 and the 2009 H1N1 pandemic influenza outbreak.

Rodolphe Barrangou
Canada Gairdner International Award
2016
For establishing and characterizing CRISPR-Cas bacterial immune defense system.
Associate Professor, Department of Food, Bioprocessing and Nutrition Sciences; Todd R. Klaenhammer Distinguished Scholar in Probiotics Research North Carolina State University, Raleigh, NC, USA

The work: Dr. Barrangou and Dr. Horvath’s research focused on understanding the genetic basis for health-promoting and technological properties of beneficial bacteria used in food fermentations. Along with colleagues, they established that CRISPR-Cas systems provide adaptive immunity against viruses in bacteria where it recognizes foreign DNA and uses a special molecular scalpel to target and destroy it. They also showed that CRISPR arrays capture viral DNA for natural vaccination against bacteriophages; and demonstrated that cas genes are implicated in sequence-specific targeting and cleavage of DNA.

The impact: Their discovery established CRISPR-Cas as the adaptive immune system of bacteria and has made dramatic impact on the science community, setting the stage for a new research area. This inspired others to investigate CRISPR further. The key advantages of CRISPR over other gene-editing systems are its ability to be quick, precise, efficient and relatively inexpensive. And, as the scientific community has shown over the past few years it is transferable to many types of living organisms. The list of possible applications includes: genome editing, antibacterial and antimicrobial production, food safety, food production and plant breeding.

Bio
Rodolphe Barrangou is an Associate Professor in the Department of Food, Bioprocessing and Nutrition Sciences at North Carolina State University, a NC State University Scholar, and the Todd R. Klaenhammer Distinguished Scholar in Probiotics Research.

Dr. Barrangou and colleagues at DuPont established the biological role of CRISPR-Cas systems in adaptive immunity in bacteria, and used CRISPR-based technologies for bacterial genotyping of industrial cultures, and for the vaccination of dairy cultures against bacteriophages. After nine years in R&D and M&A at Danisco and DuPont, he joined the faculty at NC State University in 2013.

Dr. Barrangou is the recipient of the 2014 NC State Alumni Association Outstanding Research Award, and of the 2015 NC State Faculty Scholars Award. He has been on the Thomson Reuters Highly Cited Researchers list in 2014 and 2015. Dr. Barrangou is on the board of directors of Caribou Biosciences, a co-founder and member of the Scientific Advisory Board of Intellia Therapeutics, and a founding investor of Locus Biosciences.

Dr. Barrangou has published numerous articles on CRISPR-Cas systems and their use since 2005, including establishing their role as bacterial immune systems, and exploiting them for industrial applications. Following the initial work unraveling the biological function of CRISPR arrays and cas genes, subsequent studies and collaborative efforts identified PAMs as critical sequences for phage DNA targeting, showed that Cas9 is an endonuclease which can cleave plasmid and phage DNA, and provided the first proof of concept that CRISPR can be reprogrammed and transferred heterologously. Dr. Barrangou also established and co-hosted five international CRISPR meetings, and edited the first book on CRISPR-Cas systems.

They also showed that CRISPR arrays capture viral DNA for natural vaccination against bacteriophages; and demonstrated that cas genes are implicated in sequence-specific targeting and cleavage of DNA.

The impact: Their discovery established CRISPR-Cas as the adaptive immune system of bacteria and has made dramatic impact on the science community, setting the stage for a new research area. This inspired others to investigate CRISPR further. The key advantages of CRISPR over other gene-editing systems are its ability to be quick, precise, efficient and relatively inexpensive. And, as the scientific community has shown over the past few years it is transferable to many types of living organisms. The list of possible applications includes: genome editing, antibacterial and antimicrobial production, food safety, food production and plant breeding.

Philippe Horvath is a senior scientist at DuPont. He graduated from Université Louis-Pasteur, Strasbourg, France in 1996 and obtained his Ph.D. in Cellular and Molecular Biology in 2000. That same year, he was recruited by Rhodia Food and worked at the R&D center in Dangé-Saint-Romain, France, where he contributed to the development of molecular biology tools for bacterial strain screening, microbial identification, and typing of lactic acid bacteria and their bacteriophages.

Philippe became senior scientist in 2006, two years after Rhodia Food was acquired by the Danish company Danisco, a world leader in specialty food ingredients. In 2014, three years after DuPont acquired Danisco, Philippe was appointed Associate to the DuPont Fellows Forum, and further appointed DuPont Nutrition & Health Technical Fellow in 2015.

Since late 2002, a large part of Philippe’s research activities has been dedicated to CRISPR (clustered regularly interspaced short palindromic repeats), first as a polymorphic chromosomal region useful for strain differentiation and tracking, and then as a bacterial immune system with considerable industrial, biotechnological, and medical applications. Philippe is co-inventor of 95 patents and/or patent applications, of which 62 are related to various uses of CRISPR, and co-author of 31 peer-reviewed articles (22 about CRISPR) and 4 book chapters.

Emmanuelle Charpentier
Canada Gairdner International Award
2016
For development of CRISPR-CAS as a genome editing tool for eukaryotic cells.
Director, Max Planck Institute for Infection Biology, Berlin, Germany; Professor, Umeå University, Umeå, Sweden

The work: In 2012 Dr. Charpentier and Dr. Doudna published the description of a revolutionary new genome editing technology that uses an engineered single-guide RNA together with the DNA-cleaving enzyme Cas9 to readily manipulate the genomic DNA of individual cells. The CRISPR-Cas9 technology has given biologists the equivalent of a molecular surgery kit for routinely disabling, activating or altering genes with high efficiency and precision. Their collective work has led to the breakthrough discovery of DNA cleavage by Cas9, a dual RNA- guided enzyme whose ability to cut double-stranded DNA can be programmed by changing the guide RNA sequence. Recognizing that such an activity could be employed as a molecular tool for precision genome engineering in various kinds of cells, their teams redesigned the natural dual-RNA guide as a single-guide RNA (sgRNA), creating an easy-to-use two component system.

The impact: This technology is transforming the fields of molecular genetics, genomics, agriculture and environmental biology. RNA-guided Cas9 complexes are effective genome engineering agents in animals, plants, fungi and bacteria. The CRISPR-Cas9 technology is being used in thousands of laboratories around the world to advance biological research by engineering cells and organisms in precise ways.

For development of CRISPR-CAS as a genome editing tool for eukaryotic cells.
Core Member, Broad Institute of MIT and Harvard; Robertson Investigator, New York Stem Cell Foundation; Investigator, McGovern Institute for Brain Research, Massachusetts Institute of Technology; W. M. Keck Career Development Professor in Biomedical Engineering, Departments of Brain and Cognitive Sciences and of Biological Engineering, Massachusetts Institute of Technology; Cambridge, Massachusetts, USA

The work: Dr. Zhang and his team pioneered the development of the microbial CRISPR-Cas system as a genome editing tools for function in eukaryotic cells. They demonstrated that Cas9 can be used to make modifications at multiple sites in the genome in both human and mouse cells, and that the cuts made by Cas9 can be repaired through the incorporation of a new stretch of DNA. Following this initial work, Dr. Zhang and colleagues developed a number of applications for studying biology and disease based on the CRISPR-Cas technology and discovered additional Cas enzymes with unique properties that further expand the genome editing toolbox.

The Impact: These CRISPR-Cas genome editing tools are significantly easier and cheaper to use than previous approaches for gene editing, and they are being used by tens of thousands of scientists around the world to accelerate their research. Ultimately, CRISPR-Cas technologiesmay prove to be a powerful therapeutic for treating human diseases by editing out harmful mutations.
