Bromodomain-dependent stage-specific male genome programming by Brdt [ChIP-Seq]

ABSTRACT: Male germ cell differentiation is a highly regulated multistep process initiated by the commitment of progenitor cells into meiosis and characterized by major chromatin reorganizations in haploid spermatids. We report here that a single member of the double bromodomain BET factors, Brdt, is a master regulator of both meiotic divisions and post-meiotic genome repackaging. Upon its activation at the onset of meiosis, Brdt drives and determines the developmental timing of a testis-specific gene expression program. In meiotic cells, Brdt initiates a genuine histone acetylation-guided programming of the genome by activating essential meiotic genes and repressing a M-bM-^@M-^\progenitor cellsM-bM-^@M-^] gene expression program, while M-bM-^@M-^\primingM-bM-^@M-^] a post-meiotic gene group for fu
