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.

Project description:Clinical treatment protocols for infertility with in vitro fertilization-embryo transfer (IVF-ET) provide a unique opportunity to assess the human vaginal microbiome in defined hormonal milieu. Herein, we have investigated the association of circulating ovarian-derived estradiol (E2) and progesterone (P4) concentrations to the vaginal microbiome. Thirty IVF-ET patients were enrolled in this study, after informed consent. Blood was drawn at four time points during the IVF-ET procedure. In addition, if a pregnancy resulted, blood was drawn at 4-to-6 weeks of gestation. The serum concentrations of E2 and P4 were measured. Vaginal swabs were obtained in different hormonal milieu. Two independent genome-based technologies (and the second assayed in two different ways) were employed to identify the vaginal microbes. The vaginal microbiome underwent a transition with a decrease in E2 (and/or a decrease in P4). Novel bacteria were found in the vagina of 33% of the women undergoing IVF-ET. Our approach has enabled the discovery of novel, previously unidentified bacterial species in the human vagina in different hormonal milieu. While the relationship of hormone concentration and vaginal microbes was found to be complex, the data support a shift in the microbiome of the human vagina during IVF-ET therapy using standard protocols. The data also set the foundation for further studies examining correlations between IVF-ET outcome and the vaginal microbiome within a larger study population.

Project description:This laboratory studies the structural basis of carbohydrate function in terms of adhesion and other biological processes. The Fisher lab is testing the hypothesis that the mucin-coated oral and uterine cavities present similar carbohydrate receptors that specify the bacterial ecology of both regions and the repertoire of these oligosaccharide species is hormonally regulated. This theory also suggests that certain individuals express carbohydrate receptors that make them susceptible to both periodontal disease and preterm labor. Experimental procedure: 40 mature female mice were ovariectomize . The mice were allowed to rest for two weeks to eliminate any remaining endogenous estrogen (E2) and progesterone (P4). Then the mice were separated into four groups (10 each) that received the treatment indicated. Group 1: ovariectomized mice with no supplement, only sesame oil vehicle. Group 2: ovariectomized mice with only P4 supplement (2 mg/day/mouse). Group 3: ovariectomized mice with E2 supplement (100 ng/day/mouse). Group 4: ovariectomized mice with both P4 (2 mg/day/mouse) and E2 (100 ng/day/mouse) supplement. The treatment lasted for 4 days; the steroids were dissolved in sesame oil and injected subcutaneously. After treatment, salivary glands (parotid, submandibular, and sublingual gland), submandibular lymph nodes and uterine horns with cervix were collected. Total RNA was extracted from these samples using Trizol.

Project description:Cervical mucus is a viscous fluid functioning as a uterine cervix plug. It is formed and produced by cervical glands located in the cervix. During ovulation, cervical mucus starts to become less viscous, which is a good window for non-invasive sampling. Our study focuses on the proteomic characterization of cervical mucus, which may thus act as a non-invasively acquired source of biomarkers for diseases and physiological conditions of the female genital tract. Our study aimed at two aims - the first is to optimize a proteomic workflow of cervical mucus processing. The second aim is to assess differences in the proteomic composition of cervical mucus in natural ovulatory cycles and IVF cycles with controlled ovarian hyperstimulation. The sampling was done in cooperation with women undergoing intrauterine insemination in a natural ovulatory cycle and women undergoing controlled ovarian hyperstimulation for IVF. The optimization of proteomic workflow including an analysis on an Orbitrap mass spectrometer was performed. The results revealed the protein composition and the differences of the cervical mucus between natural and stimulated uterus.

Project description:The aim of the experiment was to investigate the effects of stimulation of human endometrial organoids with estrogen (E2) and progesterone (P4) In humans, the endometrium, the uterine mucosal lining, undergoes dynamic changes throughout the menstrual cycle and in pregnancy. We adapted conditions used to establish human adult stem cell-derived organoid cultures to generate 3D cultures of human endometrium. Unlike other mucosal epithelia, the endometrium responds dramatically to ovarian sex hormones, estrogen (E2) and progesterone (P4), which regulate cyclical proliferation and differentiation of endometrial glands with concomitant dynamic temporal and spatial expression of their receptors, ERalpha and PR.
