Our previous studies demonstrate that protein tyrosine phosphatase 2 SHP2 is highly expressed in decidualized cells and governs the decidualization progress. However, the role and mechanism of SHP2 in the function of decidual cells remain unclear. Here, we screened proteins interacting with SHP2 in decidual hTERT-immortalized human endometrial stromal cells (T-HESCs) and identified Hypoxia-inducible factor-1 (HIF-1) signaling pathway as a potential SHP2-mediated signaling pathway through proximity-dependent biotinylation (BioID) analysis. Immunoprecipitation (Co-IP) revealed an interaction between SHP2 and HIF-1α, which colocalized to the nucleus in decidual cells. Furthermore, the SHP2 expression correlated with the transcriptional activation of HIF-1α and its downstream genes Beta-enolase (Eno3), Pyruvate kinase 2 (Pkm2), Aldolase C (Aldoc), and Facilitative glucose transporter 1 (Glut1). Knockdown or inhibition of SHP2 significantly reduced the mRNA and protein levels of HIF-1α and its downstream genes, as well as lactate production in decidual cells. We also established a hypoxia model of T-HESCs and 293 T cells and found that hypoxic treatment induced the expression of SHP2 and HIF-1α, which colocalized in the nucleus. SHP2 forced-expression rescued the inhibitory effects of SHP2 deficiency on HIF-1α expression and lactate production. Finally, SHP2 binds to the promoter regions of HIF-1α and its target genes (Eno3, Pkm2, Aldoc, and Glut1).

Macrophages, a key type of immune cell, are pivotal in the context of endometriosis. This study seeks to explore the interactions between endometriotic cells and macrophages. Quantitative real-time PCR (qRT-PCR) and Western blot experiments were employed to detect phosphatase and tensin homolog (PTEN) expression. Glucose consumption, lactate production, extracellular acidification rate, and oxygen consumption rate levels were used to assess cellular glycolytic capacity. The interaction between conditioned media from ectopic endometrial stromal cells (EESCs) and macrophages was investigated through co-culture experiments. The expression of M2 macrophage marker proteins and inflammatory factors was detected via qRT-PCR, immunofluorescence staining, and enzyme-linked immunosorbent assay. Cellular functions were evaluated using Cell Counting Kit-8, 5-Ethynyl-2'-deoxyuridine (EdU), and wound healing assays. We found that PTEN deficiency promoted the glycolytic activity of EESCs. Simultaneously, it significantly promoted the macrophages' polarization toward the M2 phenotype, demonstrated by increased expression of M2 markers (differentiation 206 (CD206), CD163, and (C-C motif) ligand 22 (CCL22)). Further studies revealed that PTEN-deficient EESCs increased the level of CCL2 via promoting glycolytic activity, which was reversed by glycolytic inhibitor. Moreover, lactate and conditioned media from overexpressed CCL2 EESCs facilitated M2 polarization of macrophages, while 2-deoxy-d-glucose reversed the promoting effect. Furthermore, lactate-facilitated macrophages promoted the proliferation and migration abilities of EESCs.

In this study, we analyzed mouse embryos into which liver-derived somatic mitochondria were introduced (SM-embryos). Most SM-embryos were arrested at the two-cell stage. Some of the introduced somatic mitochondria became round, while others remained elongated and large. RNA-sequencing revealed a disruption of both minor and major zygotic gene activation (ZGA) in SM-embryos. Minor ZGA did not terminate before major ZGA, and the onset of major ZGA was inhibited, as shown by histone modification analyses of histone H3 lysine 4 trimethylation and histone H3 lysine 27 acetylation. Further analysis of metabolites involved in histone modification regulation in SM-embryos showed a significantly lower NAD+/NADH ratio in SM-embryos than in control embryos. Additionally, the mitochondrial membrane potential, an indicator of mitochondrial function, was lower in SM-embryos than in control embryos.

Our objective was to characterize relationships between anti-Müllerian hormone concentrations and responses to exogenous gonadotropin stimulation in cheetahs and domestic cats. Blood samples collected before stimulation were used to measure serum anti-Müllerian hormone concentrations, which were compared to post-stimulation outcomes, including counts of retrievable oocytes or ovulation sites, oocyte quality, embryonic cleavage after in vitro fertilization, and progestogen concentrations. Anti-Müllerian hormone concentrations were also compared to outcomes in domestic cats induced to ovulate by mechanical stimulation of the vagina and cervix (simulated coitus). Greater anti-Müllerian hormone concentrations were associated with greater ovulatory response, progestogen production, and embryonic cleavage success among gonadotropin-treated cheetahs, and with greater ovulatory response among gonadotropin-treated domestic cats. Associations were moderated by age, with anti-Müllerian hormone concentration generally a greater determinant of these outcomes in older animals. Anti-Müllerian hormone concentrations alone could distinguish domestic cats with high and low ovulatory responses to exogenous hormones. However, this marker was unrelated to ovulatory response in domestic cats after simulated coitus. These results demonstrate the potential for anti-Müllerian hormone concentrations to predict responses of cheetahs and domestic cats to ovarian stimulation treatment commonly used in assisted reproductive technologies.

Prior work in mice established that a combination of continuous turnover of fibrillar collagen and reduced formation of collagen cross-links allows for the gradual increase in tissue compliance and delivery of the fetus during labor. However, the mechanism for continuous collagen degradation to ensure turnover during cervical remodeling is still unknown. This study demonstrates the functional role of extracellular and intracellular collagen degradative pathways in two different settings of cervical remodeling: physiological term remodeling and inflammation-mediated premature remodeling. Extracellular collagen degradation is achieved by the activity of fibroblast-derived matrix metalloproteases MMP14, MMP2, and fibroblast activation protein (FAP). In parallel, we demonstrate the function of an intracellular collagen degradative pathway in fibroblast cells mediated by the collagen endocytic mannose receptor type-2 (MRC2). These pathways appear to be functionally redundant as loss of MRC2 does not obstruct collagen turnover or cervical function in pregnancy. While both extracellular and intracellular pathways are also utilized in inflammation-mediated premature cervical remodeling, the extracellular collagen degradation pathway uniquely employs fibroblast and immune-cell-derived proteases. In sum, these findings identify the dual utilization of two distinct degradative pathways as a failsafe mechanism to achieve continuous collagen turnover in the cervix, thereby allowing dynamic shifts in cervical tissue mechanics and function.</p>","PeriodicalId":8965,"journal":{"name":"Biology of Reproduction","volume":" ","pages":"709-727"},"PeriodicalIF":3.1,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11996760/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142999560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
