Project description:Receptors for estrogen and progesterone frequently interact, via Cohesin/CTCF loop extrusion, at enhancers distal from regulated genes; CTCF is decreased or mutated in >20% of human endometrial tumors, indicating its importance in uterine homeostasis. To better understand how CTCF-mediated enhancer-gene interactions impact endometrial development and function, the Ctcf gene was selectively deleted in female reproductive tissues of mice. Prepubertal Ctcfd/d uterine tissue exhibited normal morphology, with a significant reduction in the number of uterine glands compared to those without Ctcf deletion (Ctcff/f mice). Post-pubertal Ctcfd/d uteri were hypoplastic with significant reduction in both the size of the endometrial stroma and number of glands. Transcriptional profiling revealed increased expression of stem cell molecules Lif, EOMES and Lgr5, and enhanced inflammation pathways following Ctcf deletion. Analysis of the response of the uterus to steroid hormone stimulation showed that the response of the uterus to estrogen was not impacted, but that CTCF deletion affects a subset of progesterone responsive genes. This finding indicates 1) mediators of P signaling remain functional following Ctcf deletion and 2) certain P regulated genes are sensitive to Ctcf deletion, suggesting they depend on gene-enhancer interactions that require CTCF. The P responsive genes altered by CTCF ablation included Ihh, Fst and Errfi1, as well as other genes involved in the regulation of critical processes including hormone response, transcription, and inhibition of tumor generation. Overall, our findings reveal that uterine Ctcf plays a key role in P dependent expression of uterine genes underlying optimal post pubertal uterine development.

Project description:Progesterone (P4) acts via the endometrium to modify the uterine environment and promotes conceptus growth for elongation and pregnancy establishment. Ewes were ovariectomized and treated with P4 for 14 days or P4 for 14 days and RU486, a progesterone receptor antagonist, from days 8 to 14. Small RNA sequencing of endometrium and EVs from the uterine lumen detected expression of 768 miRNAs and P4 regulation of 9 endometrial and 7 extracellular vesicle miRNAs.

Project description:Different progesterone levels and timing of exposure results in different endometrial gene expression and implantation potential. Sufficient progesterone level is important to induce endometrial receptivity and endometrial expressed the most receptive stage after exposure to progesterone for 7 days based on decidualisation marker expression.

Project description:The majority of pregnancy losses result from implantation failure. Successful embryo implantation involves a delicate interaction between the receptive uterus and an implantation-competent blastocyst. Understanding the mechanisms regulating the endometrial receptivity during preimplantation are essential for improving pregnancy outcomes. Mitogen-inducible gene 6 (MIG-6) is a key mediator of progesterone signaling in the endometrium.MIG-6 loss results in implantation failure due to non-receptive endometrium. We applied single cell RNA sequencing to determine the composition of different cell types and functions within non-receptive endometrium from uterine specific Mig-6 knock-out (Pgrcre/+Mig-6f/f; Mig-6d/d) mice. Mig-6d/d mice revealed altered gene expression in the epithelial and stromal cells. We identified key gene expression changes in the non-receptive endometrium of Mig-6d/d mice, providing valuable insights into the role of progesterone signaling in implantation.

Ewes were ovariectomized and treated with P4 for 14 days or P4 for 14 days and RU486, a progesterone receptor antagonist, from days 8 to 14. Interrogation of the endometrial transcriptome resulted in 1,611 differentially abundant transcripts with 931 increased and 680 decreased in P4 as compared to P4+RU treated ewes.

Project description:During early pregnancy, glucose is essential for the uterine epithelium and the developing embryo. In cows, studies have shown that progesterone increases the secretion of glucose into the uterine lumen. Nevertheless, how progesterone affects glucose metabolism in the uterine epithelium has been sparsely investigated. Therefore, our objective was to investigate how progesterone influences glucose metabolism in immortalized bovine uterine epithelial (BUTE) cells. Progesterone treatment (10 μM) increased glucose consumption. To gain a more global picture of the effects of progesterone, RNAseq was performed after BUTE cells were treated with vehicle (DMSO) or 10 μM for 24 hours. KEGG analysis indicated that progesterone altered genes associated with metabolic pathways and glutathione metabolism. Manually examining genes unique to specific glucose metabolic pathways identified an increase in the rate-limiting enzyme in the pentose phosphate pathway—glucose-6-phosphate dehydrogenase. Functionally, a major product of the pentose phosphate pathway is NADPH, and progesterone treatment increased NADPH concentrations in BUTE cells. In cows, immunohistochemistry confirmed that glucose-6-phosphate dehydrogenase levels were higher in the uterine epithelium in the luteal phase when progesterone concentrations are high. In conclusion, progesterone increased glucose-6-phosphate dehydrogenase expression and metabolism via the pentose phosphate pathway in the bovine uterine epithelium. This metabolism could provide substrates for cell proliferation, molecules to be secreted into the uterine lumen that supports embryonic development, or maintain reduction/oxidation balance in the uterine epithelium.

Project description:Uterine glands and, by inference, their secretions impact uterine receptivity, blastocyst implantation, stromal cell decidualization, and placental development. Changes in gland function across the menstrual cycle are impacted by steroid hormones, estrogen and progesterone, as well as stroma-derived factors. Using an endometrial epithelial organoid (EEO) system, transcriptome and proteome analyses identified distinct responses of the EEO to steroid hormones and prostaglandin E2 (PGE2). Notably, steroid hormones and PGE2 modulated the basolateral secretion of EEO proteins, where cystatin C (CST3) was significantly increased by progesterone and PGE2. CST3 treatment of decidualizing stromal cells significantly decreased the decidualization markers PRL and IGFBP1. The attenuation of stromal cell decidualization via CST3 suggests a role for uterine gland-derived proteins in controlling the extent of decidualization. These findings provide evidence that uterine gland-derived factors directly impact stromal cell decidualization, which has strong implications for better understanding pregnancy establishment and female fertility in humans.

Project description:Receptors for estrogen and progesterone frequently interact, via Cohesin/CTCF loop extrusion, at enhancers distal from regulated genes. Loss-of-function CTCF mutation in >20% of human endometrial tumors indicates its importance in uterine homeostasis. To better understand how CTCF-mediated enhancer-gene interactions impact endometrial development and function, the Ctcf gene was selectively deleted in female reproductive tissues of mice. Prepubertal Ctcfd/d uterine tissue exhibited a marked reduction in the number of uterine glands compared to those without Ctcf deletion (Ctcff/f mice). Post-pubertal Ctcfd/d uteri were hypoplastic with significant reduction in both the amount of the endometrial stroma and number of glands. Transcriptional profiling revealed increased expression of stem cell molecules Lif, EOMES, and Lgr5, and enhanced inflammation pathways following Ctcf deletion. Analysis of the response of the uterus to steroid hormone stimulation showed that CTCF deletion affects a subset of progesterone-responsive genes. This finding indicates (1) Progesterone-mediated signaling remains functional following Ctcf deletion and (2) certain progesterone-regulated genes are sensitive to Ctcf deletion, suggesting they depend on gene-enhancer interactions that require CTCF. The progesterone-responsive genes altered by CTCF ablation included Ihh, Fst, and Errfi1. CTCF-dependent progesterone-responsive uterine genes enhance critical processes including anti-tumorigenesis, which is relevant to the known effectiveness of progesterone in inhibiting progression of early-stage endometrial tumors. Overall, our findings reveal that uterine Ctcf plays a key role in progesterone-dependent expression of uterine genes underlying optimal post-pubertal uterine development.
