Progesterone ameliorates the endometrial polyp by modulating the signaling pathway of Wnt and ß-catenin via regulating the expression of H19 and miR-152.

BACKGROUND: MicroRNAs and long noncoding RNAs are believed to play important roles in the pathogenesis of various diseases. This study aimed to explore the potential mechanism of the involvement of H19 and miR-152 in an endometrial polyp. METHODS: Luciferase assay was conducted to determine the effect of progesterone. Real-time polymerase chain reaction (PCR) and western blot were performed to detect the influence of progesterone on miR-152 and Wnt1. MTT assay and flow cytometry (FCM) were utilized to detect the effect of progesterone on cell proliferation and apoptosis. In silicon analysis, luciferase assay, real-time PCR, and immunohistochemistry (IHC) were performed to explore the regulatory relationship between H19 and miR-152 or miR-152 and Wnt1. RESULTS: Progesterone dose-dependently increased the H19 expression level through driving the promoter efficiency of H19. Then, progesterone upregulated Wnt1 level and downregulated miR-152 in a dose-dependent manner in ECC1 and HEC1A cells. Administration of progesterone inhibited cell viability and promoted cell apoptosis. H19 negatively regulated miR-152 expression by binding to miR-152. Furthermore, Wnt1 was identified as a virtual target gene of miR-152 and was inhibited by miR-152. Progesterone receptors mRNA and miR-152 were lowly expressed in participants with an endometrial polyp, while the levels of H19 and Wnt1 were much higher in the endometrial polyp group compared with normal controls. H19 negatively regulated miR-152 and miR-152 negatively regulated Wnt1, with the negative correlation coefficients being -0.500 and -0.500, respectively. Using IHC, it was found that Wnt1 and Bcl-2 protein were highly expressed in the endometrial polyp group compared with normal controls. CONCLUSION: The results suggested that H19 was associated with endometrial polyp via mediating cell proliferation and apoptosis.

Depression outcome in women with recurrent spontaneous abortion: A systematic review and meta-analysis.

BACKGROUND: It is widely recognized that depression is highly prevalent among women experiencing recurrent spontaneous abortion (RSA), exerting detrimental effects on both the individual and the family. OBJECTIVE: To assess the depression risk and associated factors among women with RSA. DATA SOURCES: Our search strategy encompassed PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure (CNKI), and WANFANG. The research was conducted in May 2022. We included both randomized and nonrandomized studies that reported the prevalence of depression among women with RSA. DATA EXTRACTION AND SYNTHESIS: Two independent evaluators reviewed the titles and abstracts, assessed the full-text papers, extracted data from the included studies, and evaluated their quality using the Newcastle-Ottawa Scale (NOS). We performed random-effects meta-analyses to pool the data. Odds ratios (ORs) and standardized mean differences (SMDs) were combined based on effect sizes for binary and continuous outcomes. MAIN OUTCOMES: To conduct a meta-analysis to understand the risk of depression in women with RSA who were not treated with psychiatric medications, as well as an analysis of potential factors for depressive symptoms. RESULTS: Out of the initially identified 527 papers, a total of 20 studies (N = 13087) that fulfilled the inclusion criteria were selected. Compared to healthy controls, patients with RSA had a significantly higher risk of depression (OR: 4.26, 95 % confidence interval [CI]: 2.44-7.41; SMD: 0.89, 95 % CI: 0.51-1.26). The occurrence of depression among RSA patients was found to be significantly associated with several factors including the severity of depressive symptoms (OR: 3.82, 95 % CI: 2.22-6.59), number of spontaneous miscarriages (SMD: 0.59, 95 % CI: 0.01-1.18), history of therapeutic termination of pregnancy (SMD: 0.20, 95 % CI: 0.09-0.32), history of live birth (SMD: -0.32, 95 % CI: -0.49--0.15), and duration of marriage (SMD: 0.15, 95 % CI: 0.02-0.27). CONCLUSIONS: In clinical practice, it is crucial to provide appropriate psychological interventions for women undergoing RSA. These individuals face a significantly heightened risk of depression, which exhibits strong correlations with various demographic factors such as the severity of depressive symptoms, history of both spontaneous miscarriages and therapeutic termination of pregnancy, number of live births, and duration of marriage. Consequently, women who are suffering RSA deserves more assistance and emotional support.
