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.

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.

Project description:Ovarian estrogen (E2) and progesterone (P4) are indispensable for embryo-implantation and endometrial stromal decidualization; however, the molecular mechanisms that underpin these reproductive processes are unclear. Steroid receptor coregulator-2 (SRC-2) belongs to the multifunctional SRC/p160 family which also includes SRC-1 and SRC-3. Sharing strong sequence homology, all three SRCs exert diverse regulatory effects by modulating the transcriptional potency of nuclear receptor family members, including the estrogen and progesterone receptor (ER and PR respectively). Importantly, absence of SRC-2 in PR positive cells in the epithelial, stromal, and myometrial compartments of the murine uterus results in a striking infertility defect. This reproductive phenotype highlights a key role for SRC-2 in uterine function which is not shared with other coregulators. Intriguingly, abrogation of uterine SRC-2 does not block embryo apposition or attachment to the apical surface of luminal epithelial cells of the endometrium but rather prevents P4-dependent local decidualization of the sub-epithelial stroma. Remarkably, epithelial-specific ablation of SRC-2 in the murine uterus does not compromise endometrial functionality, again underscoring the unique importance of stromal derived SRC-2 in uterine function. The stromal decidualization defect resulting from SRC-2 ablation is reflected at the molecular level by a marked attenuation in P4 responsive target genes known to be critical for P4 dependent decidualization (i.e. ERBB receptor feedback inhibitor 1, Follistatin and Fkbp5). Conversely, the induction of E2 or P4 target genes involved in embryo implantation (i.e. leukemia inhibitory factor (LIF) and Indian hedgehog (Ihh) respectively) is not affected by SRC-2’s absence. As with mouse studies, decidualization of primary human stromal cells (HESCs) in culture is blocked by SRC-2 knockdown; however, HESC decidualization is unaffected by knockdown of SRC-1 or SRC-3. As a consequence of SRC-2 knockdown, molecular studies disclose a striking decrease in the induction of a subset of P4 target genes (i.e. WNT4 and FKBP5) which are essential for the stromal-epithelioid transformation step, the cellular hallmark of endometrial decidualization. Collectively, these studies not only showcase the evolutionary importance of SRC-2 in endometrial biology but also suggest that deregulation of this coregulator may underpin a spectrum of hormone-dependent uterine pathologies such as endometriosis and endometrial cancer. Microarray analysis was performed on mouse uteri using eighteen SRC-2flox/flox (SRC-2f/f) and eighteen PRCre/+ SRC-2flox/flox (SRC-2d/d) mice. Mice were ovariectomized at 6 weeks and after 2 weeks mice were either treated with sesame oil (vehicle) or 1 mg of P4. RNA from three mice per genotype per treatment were pooled and assigned as one sample (three samples per genotype per treatment). multiple group comparison

Project description:Progesterone (P4) is essential to prepare the endometrium for a successful pregnancy. While P4 resistance is a major cause of infertility that leads to endometrial disorders, such as endometriosis, the underlying epigenetic imbalance responsible for P4 resistance in the endometrium remains unclear. We demonstrated that CXXC finger protein 1 (CFP1), a major mediator of histone H3 lysine 4 trimethylation (H3K4m3), is an indispensable factor in the maintenance of epigenetic landscapes of P4-progesterone receptor (PGR) signaling networks in the uterus. Cfp1flox/flox;Pgr-Cre (Cfp1d/d) mice suffered from impaired P4 responses, leading to abnormal uterine cell proliferation and complete failure of embryo implantation and decidualization, albeit regular estrous cycle with normal hormone profiles. mRNA and chromatin immunoprecipitation sequencing analyses showed that CFP1 binding enriches promoter regions to regulate uterine mRNA landscapes not only in H3K4me3-dependent but also in H3K4me3-independent manners. Especially, CFP1 directly regulates subsets of important P4 response genes, including Gata2, Sox17, and Ihh, which mediate the activation of the smoothened signaling pathway in the uterus. P4 cannot interfere with E2 actions on uterine epithelial proliferation in Cfp1d/d mice, which was restored by supplementing a smoothened agonist (SAG). Furthermore, ectopic lesions of Cfp1d/d uterus in an endometriosis model showed P4 resistance, which was rescued by SAG. In human endometriosis, CFP1, GATA2, SOX17, and IHH, were significantly downregulated, and a positive correlation was found in the expression levels between CFP1 and these P4 targets regardless of PGR levels. Collectively, we suggest that CFP1 is an epigenetic modulator of P4-PGR signaling networks to promote uterine receptivity for embryo implantation and suppress endometriosis with P4 resistance. CFP1 is a key epigenetic factor that intervenes in the P4–epigenome–transcriptome networks for uterine function under physiologic and pathophysiologic conditions.
