(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) After fertilization of the transcriptionally silent oocyte, expression from both parental chromosomes is launched through so-called zygotic genome activation (ZGA), occurring in the mouse at the 2-cell (2C) stage. Amongst the first elements to be transcribed are the Dux gene, the product of which secondarily induces a wide array of ZGA genes, and a subset of evolutionary recent LINE-1 retrotransposons, which regulate chromatin accessibility in the early embryo. more...

(Submitter supplied) How maternal factors in oocytes initiate zygotic genome activation (ZGA) remains elusive. Recent studies indicate that DPPA2 and DPPA4 are required for establishing a 2-cell embryo-like (2C-like) state in mouse embryonic stem cells (ESCs) in a DUX-dependent manner. These results suggest that DPPA2 and DPPA4 are essential maternal factors that regulate Dux and ZGA in embryos. By analyzing maternal knockout and maternal-zygotic knockout embryos, we unexpectedly found that Dux activation, ZGA, and preimplantation development are normal in embryos without DPPA2 or DPPA4. more...

(Submitter supplied) Zygotic Genome Activation (ZGA) represents the initiation of transcription following fertilization. Despite its importance in shifting developmental control from primarily maternal stores in the oocyte to the embryo proper, we know little of the molecular events that initiate ZGA in vivo. Recent in vitro studies in mouse embryonic stem cells (ESCs) have revealed Developmental Pluripotency Associated 2 and 4 (Dppa2/4) as key regulators of ZGA-associated transcription. more...

(Submitter supplied) In metazoans, the fertilized embryo is transcriptionally mostly silent for a few cell divisions, until release of a first major wave of embryonic transcripts by so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identified in Drosophila melanogaster and Danio rerio but their mammalian homologues are still undefined. Here, we reveal that DUX family transcription factors are key to this process in human and mouse. more...

(Submitter supplied) How maternal factors in oocytes trigger zygotic genome activation (ZGA) is a long-standing question in developmental biology. Recent studies in 2-cell like embryonic stem cells (2C-like cells) implicate that the DUX family transcription factors are key regulators of ZGA in placental mammals. To characterize the role of DUX in ZGA, we generated Dux cluster knockout (KO) mouse lines. Unexpectedly, we found both Dux zygotic KO (Z-KO) and maternal/zygotic KO (MZ-KO) embryos can survive to adulthood despite showing reduced developmental potential. more...

(Submitter supplied) Upon fertilization, drastic chromatin reorganization occurs during human preimplantation development. However, the global chromatin landscape and its molecular dynamics in this period remain largely unexplored. Deciphering such process is crucial for understanding both early human development and in vitro fertilization. Here, we investigated genome-wide chromatin accessibility in human preimplantation embryos by employing an improved ATAC-seq that uses as few as 20 cells. more...

(Submitter supplied) Zygotic genome activation (ZGA) is a crucial developmental milestone that remains poorly understood. This first essential transcriptional event in embryonic development coincides with extensive epigenetic reprogramming and is orchestrated, in part, by the interplay of transcriptional and epigenetic regulators. Here, we developed a novel high-throughput screening method that combines pooled CRISPR-activation (CRISPRa) with single-cell transcriptomics and applied this method to systematically probe candidate regulators of ZGA-like transcription. more...

(Submitter supplied) Zygotic genome activation (ZGA) activates the quiescent genome to enable the maternal-to-zygotic transition. However, the identity of transcription factors (TFs) that underlie mammalian ZGA in vivo remains unresolved. Here, we showed that OBOX, a PRD-like homeobox domain TF family that includes 66 members (OBOX1-8), are key regulators of mouse ZGA. Knockout mice deficient for maternally transcribed Obox1/2/5/7 and zygotically expressed Obox3/4 led to 2-4 cell arrest accompanied by impaired ZGA. more...
