(Submitter supplied) Zygotic genome activation (ZGA) marks the beginning of the embryonic program for a totipotent embryo, which gives rise to inner cell mass (ICM), where pluripotent epiblast arises, and extraembryonic trophectoderm. While much has been learned about pluripotency regulation, how ZGA is connected to the first lineage segregation in early embryos remains elusive. Here, we investigated the role of nuclear receptor transcription factors (NR TFs), whose motifs are highly enriched in accessible chromatin at the 2-cell (2C) to 8-cell (8C) stages after ZGA. more...

(Submitter supplied) During the first lineage segregation, a mammalian totipotent embryo differentiates into inner cell mass (ICM) and trophectoderm (TE). However, how transcription factors (TFs) regulate this earliest cell fate decision in vivo remains elusive, with their regulomes primarily inferred from cultured cells. Here, we investigated the TF regulomes during the first mouse lineage specification across 6 stages, spanning the pre-initiation, initiation, commitment, and maintenance phases. more...

(Submitter supplied) Life begins with a switch in genetic control from the maternal to the embryonic genome during zygotic genome activation (ZGA). Despite its importance, the essential regulators of ZGA remain largely unknown in mammals. Based on de novo motif searches, we identified the orphan nuclear receptor Nr5a2 as a key activator of major ZGA in mouse 2-cell embryos. Nr5a2 is required for progression beyond the 2-cell stage. more...

(Submitter supplied) Pioneer transcription factors (TFs), such as OCT4 and SOX2, play crucial roles in pluripotency regulation. However, the master TF-governed pluripotency regulatory circuitry was largely inferred from cultured cells. In this work, we investigated SOX2 binding from embryonic day 3.5 (E3.5) to E7.5 in the mouse. In E3.5 inner cell mass (ICM), SOX2 regulates the ICM-trophectoderm program but is dispensable for opening global enhancers. more...

(Submitter supplied) The molecular regulation of zygotic genome activation (ZGA) in mammals remains poorly understood. Primed mouse embryonic stem cells contain a rare subset of “2C-like” cells that are epigenetically and transcriptionally similar to the two cell embryo and thus represent an ideal system for studying ZGA transcription regulation. Recently, the transcription factor Dux, expressed exclusively in the minor wave of ZGA, was described to activate many downstream ZGA transcripts. more...

(Submitter supplied) The remodelling of the epigenome and transcriptome of the fertilised oocyte to establish totipotency in the zygote and developing embryo is one of the most critical processes in mammalian embryogenesis. Zygotic or embryonic genome activation (ZGA, EGA) in the 2-cell embryo in mouse, and the 8-cell embryo in humans, constitutes the first major wave of transcription. Failure to initiate ZGA leads to developmental defects, and contributes to the high attrition rates of human pre-implantation embryos. more...
