Evolutionary Epigenomics and Genetic Conflicts

AccueilÉquipesEvolutionary Epigenomics and Genetic Conflicts
Access to genetic information is organized by epigenetic modifications and chromatin pathways. These mechanisms predate the last common ancestor to all eukaryotes and are hypothesized to perform conserved functions. Nevertheless, we find that they are subject to diversification in mammals (see publications). Genetic conflicts are well known to drive genome diversification, however their impact on epigenome evolution is poorly understood. Our team uses phylogenetics to identify chromatin pathways with evolutionary signatures of genetic conflicts, and test their function on the epigenome in vivo.

Recherche

Currently, the Molaro Lab uses mouse models, mammalian cell culture and comparative epigenomics to answer the following questions:

1)    What are the functions of protein domains subject to diversification in chromatin modifying enzymes?

2)    Which evolutionary forces drive short histone H2A variants diversification in mammals?

3)    How do short H2As imprint parental epigenomes during mammalian reproduction?

4)    How does epigenome evolution shape normal development and disease progression in humans?
