Project description:To identify whether Cdx2 or Gata3 can activate trophoblast specific gene expression when expressed in R1 ES cells. To assess the dependency of Gata3 activity on Cdx2, Gata3 was also expressed in Cdx2-null ES cells. Keywords: gene expression a fusion construct of either Cdx2 or Gata3 and the tamoxifen responsive estrogen receptor ligand binding domain was expressed in R1 ES cells. Cell were induced with tamoxifen for 6 days to activate the transcription factor and cultured under trophoblast stem cell conditions

Project description:The first lineage decisions during mouse development lead to establishment of embryonic and extraembryonic tissues. The transcription factor Cdx2 plays a central role by repressing pluripotency genes, such as Oct4 and promoting trophoblast fate at the blastocyst stage. Here we show that the transcription factor Gata3 is coexpressed with Cdx2 in the blastocyst and that overexpression of Gata3 in embryonic stem cells is sufficient to induce expression of trophoblast genes. Gata3 expression in the blastocyst does not depend on Cdx2, nor do Gata3 overexpressing cell lines require Cdx2 for expression of a subset of trophoblast genes. In the embryo, expression of Gata3, like Cdx2, depends on Tead4, and expression of both factors becomes restricted to nascent trophoblast by an Oct4-independent mechanism. These observations place Tead4 at the top of a trophoblast hierarchy, with Gata3 and Cdx2 acting downstream to induce expression of common and independent targets in this lineage. This SuperSeries is composed of the following subset Series: GSE12985: Differentiation time course of trophoblast stem cells GSE12986: Expression of Cdx2 or Gata3 in R1 mouse embryonic stem cells

Project description:In this study, we perform multiple gain- and loss-of-function of TEAD4, CDX2 or GATA3 to study their roles in the trophoblast transition from BMP4-treated human embryonic stem cells (hESCs). Although hESCs with TEAD4 deletion maintain in pluripotency, their potential of trophoblast transition is attenuate. We then performed large-scale transcriptome analysis to explore more information.

Project description:Current understandings of the initiation of the trophectoderm (TE) program in mammalian embryonic development lacks evidence of how TE-associated factors such as CDX2 and GATA3 participate in bovine lineage specification. In this study, we describe the effects of TE-associated factors on lineage specification marker genes such as SOX2, OCT4, NANOG, GATA6 and SOX17, assisted by a cytosine base editor system. Interestingly, GATA3 downregulates the NANOG expression in bovine blastocysts. Further analysis of the blastocyst mosaic shows that GATA3 is required for NANOG in TE cells of bovine blastocysts. It is worthy to notice that, unlike mouse embryos where GATA3 and CDX2 did not reciprocally affect each other in bovine embryos.

Project description:A) Chromatins were prepared from Cdx2-inducible ES cells cultured for 48 - 60 hours in the Dox+ and Dox- conditions. Chromatin immunoprecipitation (ChIP) was carried out by using anti-FLAG M2 affinity gel. ChIP product was tested by Western blotting using anti-FLAG antibody. Nuclear extract from ES cells cultured for 48 - 60 hours in Dox+ and Dox- condition was used for the Western blot. B) CDX2 ChIP-Seq peaks in the Hoxa7 gene region. UCSC Mouse Mm9 browser view of Hoxa7 gene locus after mapping CDX2 ChIP-Seq tags locations in the wiggle format. CDX2 ChIP-Seq peaks are shown in red color. C) Cdx2 ChIP-Seq result was verified by qPCR. Target genes were indicated in (G). Primers flanking a promoter region of Hbb-b1 and Pou5f1 as well as a gene desert region in chromosome 3 were used as negative controls. Primers flanking of Actb gene promoter were used for normalization. The relative enrichment of CDX2 binding was indicated as fold change. (D) CDX2-binding motifs identified with CisFinder using 200 bp sequences centered at ChIP sites. (F) Potential CDX2-direct target genes based on ChIP-Seq and the alteration of expression by Cdx2-overexpression. (G) Identification of CDX2 target genes by combining information on binding sites with gene expression response to Cdx2 over-expression

MC1 ES cells were genetically modified for ROSA26 locus to have Tet-Off expression cassette for C-terminal FLAG tagged Cdx2. The peaks are obtained from the Eland Multi Alignment file. The number of tags in peaks was compared with the number of tags in the control sample for the same region corrected by the total coverage of tags. See supplemental file of the paper for details.
