Project description:To better understand transcriptional regulation during human oogenesis and pre-implantation embryonic development, we defined stage-specific transcription, which revealed cleavage stage as highly distinctive. We present multiple lines of evidence that two cleavage-specific homologs, mouse mDUX and human DUX4, each activate hundreds of cleavage-specific endogenous genes (e.g. ZSCAN4, ZFP352, KDM4E) and retroviral elements (MERVL/HERVL-family). Remarkably, mDux expression converts mouse ESCs into two-cell embryo-like (2C-like) cells by binding to MERVL promoters/enhancers and restoring the chromatin landscape (via ATACseq) to the pattern of mouse two-cell embryos
