Project description:The role of Gata2 in regulating uterine function including fertility, implantation, decidualization and P4 signaling in the mouse was investigated by the conditional ablation of Gata2 in the uterus using the (PR-cre) mouse and ChIP-seq for in vivo GATA2 binding sites in the murine uterus upon acute P4 administration. Gata2 gene ablation was confirmed by real-time PCR analysis in the PR-cre; Gata2fl/fl (termed Gata2d/d) uterus. While littermate controls are fertile, Gata2d/d females are completely infertile. Analysis of the infertility indicates that implantation does not occur, and the uterine stroma is incapable of undergoing the decidual reaction to support further embryonic development. Measure of P4 target genes including PR itself indicate a block in P4 target gene induction and that Gata2 regulates PR expression directly. Microarray analysis demonstrates that ablation of Gata2 leads to specific gene changes, including disruption of the Wnt signaling pathway, Progesterone receptor (PR) signaling, and Ihh signaling pathway. In addition we identified 46,183 GATA2 binding sites in P4 treatment conditions with 7,954 binding sites overlapping that of the PR.Taken together, these data demonstrate that Gata2 is a critical regulator of gene expression and function in the murine uterus.

Project description:Progesterone (P4) signaling through its nuclear transcription factor, the progesterone receptor (PR), is essential for normal uterine function. Although deregulation of PR mediated signaling is known to underscore uterine dysfunction and a number of endometrial pathologies, the early molecular mechanisms of this deregulation are unclear. To address this issue, we have defined the genome-wide PR and GATA2 cistrome in the murine uterus using chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-seq). In uteri of ovariectomized mice, we identified 6367 PR binding sites in the absence of P4 ligand; however, this number increased at nearly three fold (18,432) following acute P4 exposure. Sequence analysis revealed that approximately 73% of these binding sites contain a progesterone response element (PRE) or a half-site motif recognized by the PR. Many previously identified P4 target genes known to regulate uterine function were found to contain PR binding sites, confirming the validity of our methodology. In addition we identified 46,183 GATA2 binding sites in P4 treatment conditions with 7,954 binding sites overlapping that of the PR.
