Méiose et recombinaison
La méiose est une division cellulaire spécialisée qui permet chez les organismes à reproduction sexuée de former des cellules haploïdes à partir de cellules diploïdes. Ceci est réalisé par un cycle cellulaire constitué d’une phase de réplication de l’ADN suivi par deux divisions. La ségrégation réductionnelle des chromosomes lors de la première division de méiose nécessite l’établissement de connections entre chromosomes homologues. Celles-ci sont établies pendant la prophase de la première division par recombinaison homologue qui génère des échanges réciproques, appelés crossing over, entre homologues. L’absence de crossing over conduit le plus souvent à des défauts de ségrégation et à la stérilité. Des altérations du programme de recombinaison peuvent aussi conduire à de l’instabilité génomique et à des aneuploïdies. Par ailleurs, les événements de recombinaison homologues en méiose déterminent les associations génétiques et contribuent à la diversité des génomes et à leur évolution.
Notre equipe s’intéresse à plusieurs aspects du mécanisme moléculaire de la recombinaison méiotique et de ses implications évolutives en utilisant la souris comme système modèle. La recombinaison méiotique est initiée par l’induction programmée de centaines de cassures double brin de l’ADN dont la réparation conduit à la formation de crossing over et conversion géniques. Les principales étapes et facteurs impliqués dans ces processus ont été conservés au cours de l’évolution.
