Dynamic landscape of enhancer-derived RNA during mouse early embryo development

Project description:Enhancer RNAs (eRNAs) play critical roles in diverse biological processes by mediating the activation of their target genes. However, the systematic landscape and potential regulations and functions of eRNAs during mammalian early embryo development remains elusive. Here, we present the comprehensive detection and characterization of eRNAs during mouse early embryo development. We demonstrated the spatiotemporal and allelic landscape of eRNA expression. We found the asymmetric activation of paternal-specific eRNAs during zygotic genome activation (ZGA). We identified TFs and their cooperation in regulating dynamic eRNA expression. eRNA are involved in multiple developmental signaling pathways through putatively regulating their target genes. Interestingly, we observed that the transcriptions of enhancers themselves are also widely modulated by eRNAs during mouse early embryo development. Critically, we de novo identified a novel eRNA transcribed from a super-enhancer region exclusively expressed at 2-cell stage of mouse early embryos and experimentally validated its key functional role in regulating ZGA and early embryo development.

Dynamic of intrauterine crosstalk promotes embryo implantation in early pregnancy

Project description:The success of early pregnancy depends largely on the successful implantation of the embryo. Dynamic crosstalk between embryo and mother plays a crucial role in this process, but our understanding is still limited. Here, using the pig as a model, we first comprehensively profile the single-cell transcriptome of early free embryos and corresponding maternal endometrium, identifying embryonic and matched endometrial cells with heterogeneity. We developed a novel tool, ExtraCellTalk, to predict crosstalk between the early embryo and the maternal uterus using uterine luminal proteins as bridges, generating an overall dynamic map of maternal-fetal crosstalk. Through cross-species comparisons, we identified a conserved RBP4/STRA6 pathway in which embryonic-derived RBP4 targets the STRA6 receptor on stromal cells in the endometrium, thereby interacting with endothelial and perivascular cells to regulate their interconversion to promote endometrial remodeling. These maternal-fetal crosstalks and corresponding endometrial changes that we uncovered are essential for subsequent embryo implantation and are the basis for further studies to improve embryo implantation.

Dynamic enhancer landscape in postmitotic motor neurons

Project description:Generic spinal motor neuron identity is specified by cooperative binding of selector transcription factors to motor neuron specific enhancers. Whether these enhancers remain active to maintain the motor neuron expression program following downregulation of selector factors in maturing motor neurons remains unknown. We demonstrate that enhancers established by selector genes are highly transient during motor neuron differentiation. The chromatin immunoprecipitation-exonuclease (ChIP-exo) assay reveals that Isl1 is anchored to nascent motor neuron enhancers through protein-protein interaction. Stage-specific recruitment of transcription factors correlates with active enhancer marks. The majority of genes contain distinct early and late enhancers suggesting that the motor neuron expression program is maintained by a dynamic regulatory landscape.

Human embryo and trophoblast proteome

Project description:Comprehensive quantitative proteomic study of human pre-implantation embryo stages reveal dynamic proteome landscape from M2, 8-cell and blastocyst stage, and during trophoblast stem cell (TS) differentiation. Identified key factors in early human embryos and lineage-specific trophoblast proteome profiles, correlated with transcriptomic analyses. This direct proteomic analysis provides a comprehensive analysis of the dynamic protein expression in human embryos during pre-implantation development and a powerful resource to enable further mechanistic studies on human trophoblast development and function.
