Découvrez notre revue « Dernières nouvelles du chromosome X: des principes généraux nuancés » écrite par Madeleine Moscatelli et Claire Rougeulle dans le journal Médecine/Sciences
Research in the Rougeulle lab focuses on the emblematic process of X chromosome inactivation, with the aim to elucidate how such a chromosome-wide epigenetic silencing is achieved and regulated in various mammalian species. More generally, we are interested in the epigenetic control of gene expression in relation to cell identity and fate, the contribution of long noncoding RNA genes and transposable elements to these processes and the plasticity of epigenetic regulations in evolution.
We use a variety of mouse and primate pluripotent stem cells and their differentiated derivatives to recapitulate key developmental stages and cellular states. Our experimental strategy combines genome engineering (CRISPR) with single cell analyses, large scale transcriptomic and epigenomic investigations and 3D topological studies.
