Chromatin structure is defined by several parameters such as combination of histone post-translational marks, nucleosome occupancy, DNA methylation or incorporation of histone variants. Chromatin structure contributes to the epigenetic regulation of gene expression, DNA replication or DNA repair. The polycomb proteins maintain gene silencing throughout development. In their absence, development is impaired as a consequence of alterations in various biological processes such as differentiation, cell identity or proliferation. Furthermore, the polycomb machinery is often altered in pathologies such as cancer.
We are investigating how the polycomb machinery is targeted to specific loci of the chromatin and how this targeting is regulated during cell differentiation. We are also studying whether alterations of the polycomb machinery are a cause or a consequence of the tumorigenic progression.
