Interests, Projects, Ideas

The post-meiotic male genome programming is a fundamental process still poorly known. It is associated with a complete reorganization of the genome, since the majority of histones are replaced by other proteins that specifically bind to the male genome allowing its compaction it in the sperm that are protamines. Although this is a phenomenon of great importance in particular to ensure the integrity of the male genome during fertilization and its transmission to the embryo, we know virtually nothing about the fundamental mechanisms that direct it. Our work focuses on the identification and functional characterization of the factors involved in this process. It is generally accepted that the removal of histones and their replacement by transition proteins and protamines is preceded by a wave of hyperacetylation of chromatin in germ cells early in their elongation. In our laboratory, the in silico research for bromodomain-containing factors whose expression is exclusively testicular and capable of interacting specifically with lysine acetylated histones, identified two proteins; the first Brdt a double bromodomain factor, and the second, Atad2, a factor having a bromodomain and a AAA-ATPase domain. The discovery of these factors has significance not only for fertility but also for the understanding of tumorigenesis. Indeed, although the expression of these factors is testis-specific, it is greatly increased in several types of cancer. They belong to the family of "Cancer Testis Antigens". This has a double significance; they could be used as biomarkers for the diagnosis of patients and at the same time they are therapeutic targets of great importance thanks to their bromodomain and the ATPase domain. We are also interested in deciphering the role of histone variants as well as the recently discovered post-translational modifications of histones in the male genome progamming of germ cells and the impact of the deregulation of their expression in cancer.
