Teams in this unit investigate the mechanisms underlying the stability and the plasticity of genetic and epigenetic information in normal or pathological contexts such as cancer. Using complementarity approaches, we develop an integrated view of the functional organization of the genome at different scales: from the molecule to the cell to the organism.
"Spermiogenesis is a radical case of differentiation whereby sperm cells acquire a compact and specialized morphology to accommodate the constraints of sexual reproduction while preserving their main cargo, an intact copy of the paternal genome. In animals, this often involves the replacement of most histones by sperm-specific nuclear basic protei
"Homologous recombination (HR) templates DNA double-strand break (DSB) repair off an intact homologous dsDNA “donor” molecule, which can exist in the form of a sister chromatid, a homologous chromosome, or dispersed repeats. HR fidelity partly depends on this competitive donor selection process, which embeds homology sampling by the RecA/Rad51
