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 contractile dysfunction leads to pregnancy complications such as preterm birth and labor dystocia. Progesterone is necessary to suppress uterine contractions to prevent premature labor. As humans maintain high levels of progesterone throughout parturition, a functional progesterone withdrawal hypothesis suggests that relative levels of myometrial progesterone receptor isoforms PGR-A and PGR-B switch at parturition, where PGR-B promotes a relaxed state and PGR-A result in increased uterine contractility. Our objective is to determine the effects of altered levels of PGR-B and PGR-A in the mouse myometrium on pregnancy and parturition using transgenic mouse models in which the relative levels of these isoforms are altered specifically in the myometrium. Overexpression of PGR-B is associated with a markedly increased gestational length compared to control mice. In both ex vivo and in vivo experiments, myometrium of PGR-B overexpressing mice have prolonged labor, a significant decrease in uterine contractility, and a high incidence of labor dystocia. Conversely, overexpression of PGR-A is associated with an increase in uterine contractility without a change in gestational length. Uterine RNAseq at mid-pregnancy identified isoform-specific downstream targets and genes that were commonly regulated by both PGR isoforms. Gene signature analyses further revealed that PGR-B promotes muscle relaxation and that PGR-A is pro-inflammation. High levels of PGR-B manifest a genetic profile of a blunted phospholipase C pathway that mediates oxytocin and angiotensin II induced muscle contraction. These findings provided in vivo support that PGR isoform levels determine distinct transcriptomic landscapes and pathways in myometrial function and labor.

Project description:Epithelial-stromal interactions in the uterus are required for normal uterine functions such as pregnancy, and multiple signaling pathways are essential for this process. Although Dicer and microRNAs (miRNA) have been implicated in several reproductive processes, the specific role of Dicer and miRNA in uterine development is not known. To address the roles of miRNA in the regulation of these key uterine pathways, we generated a conditional knockout (cKO) of Dicer in the postnatal uterine epithelium and stroma using progesterone receptor (PR)-Cre. These Dicer cKO are sterile with small uteri, which demonstrate significant defects including absence of glandular epithelium and enhanced stromal apoptosis, beginning at postnatal day 15 with expression of Cre and deletion of Dicer. Although these mice had normal serum steroid hormone levels, critical uterine signaling pathways, including progesterone-responsive genes, Indian hedgehog signaling, and the Wnt/Beta-catenin canonical pathway, were dysregulated at the mRNA level.

Project description:Here, gene profiles in rat spermatogonial stem cell lines are compared to publicly available mouse, monkey and human spermatogonial gene profiles. Interestingly, rat spermatogonia expressed metabolic control factors Foxa1, Foxa2 and Foxa3. Germline Foxa2 was enriched in Gfra1Hi and Gfra1Low undifferentiated A-single spermatogonia. Foxa2-bound loci in spermatogonial chromatin were over-represented by conserved stemness genes (Dusp6, Gfra1, Etv5, Rest, Nanos2, Foxp1) that intersect bioinformatically with conserved glutathione/pentose phosphate metabolism genes (Tkt, Gss, Gclc, Gclm, Gpx1, Gpx4, Fth), marking elevated spermatogonial GSH:GSSG. Cystine-uptake and intracellular conversion to cysteine typically couple glutathione biosynthesis to pentose phosphate metabolism. Rat spermatogonia, curiously, displayed poor germline stem cell viability in cystine-containing media, and, like primate spermatogonia, exhibited reduced transsulfuration pathway markers. Exogenous cysteine, cysteine-like mercaptans, somatic testis cells and ferroptosis inhibitors counteracted the cysteine starvation-induced spermatogonial death and stimulated spermatogonial growth factor activity in vitro.

Project description:Progesterone (P4) acting through its cognate receptor, the progesterone receptor (PR), plays an important role in uterine physiology. The PR knockout (PRKO) mouse has demonstrated the importance of the P4-PR axis in the regulation of uterine function. To define the molecular pathways regulated by P4-PR in the mouse uterus, Affymetrix MG U74Av2 oligonucleotide arrays were used to identify alterations in gene expression after acute and chronic P4 treatments. In the analysis, retinoic acid metabolic genes, cytochrome P 450 26a1 (Cyp26a1), alcohol dehydrogenase 5, and aldehyde dehydrogenase 1a1 (Aldh1a1); kallikrein genes, Klk5 and Klk6; and specific transcription factors, GATA-2 and Cited2 [cAMP-corticosterone-binding protein/p300-interacting transactivator with glutamic acid (E) and aspartic acid (D)-rich tail], were validated as regulated by the P4-PR axis. Identification and analysis of these responsive genes will help define the role of PR in regulating uterine biology. Ovariectomized wild-type and progesterone receptor knockout mice were injected with either vehicle or 1 mg/mouse progesterone. The injections were repeated every 12 h, and groups of mice were killed 4 h after the first injection (acute P4 treatment) or 4 h after the fourth injection (chronic P4 treatment).

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.
