Frédérick Antoine Mallette

Les cellules normales possèdent des mécanismes intrinsèques de suppression tumorale permettant d’éviter l’apparition de mutations génétiques contribuant à la formation de cancers. La sénescence cellulaire s’oppose au processus de transformation et se définit comme un arrêt permanent du cycle cellulaire durant lequel la cellule demeure métaboliquement active mais insensible aux stimuli de prolifération. La méthylation des histones joue un rôle crucial lors de la sénescence en permettant la répression stable de gènes impliqués dans la progression du cycle cellulaire.

Nous proposons donc d’investiguer la fonction biologique des déméthylases des histones lors de différents processus cellulaires dont le cycle cellulaire, la régulation de l’expression génique la réponse aux dommages à l’ADN ainsi que la tumorigénèse. L’objectif de nos recherches est d’élucider le rôle des modifications épigénétiques dans le cancer afin de développer de nouvelles thérapies contre le cancer.
