Abstract
Leydig cell (LCs) apoptosis is responsible for decreased serum testosterone levels during late-onset hypogonadism (LOH). Our study was designed to illustrate the regulatory effect of lncRNA XIST on LCs and to clarify its molecular mechanism of action in LOH. The Leydig cells (TM3) was treated by 300 μM H2O2 for 8 h to establish Leydig cell oxidative stress model in vitro. The expression levels of lncRNA XIST in the testicular tissues of patients with LOH were measured using fluorescence in situ hybridization (FISH). The interaction between lncRNA XIST/SIRT1 and miR-145a-5p was assessed using starBase and dual-luciferase reporter gene assays. Apoptotic cells and Caspase3 activity were determined by flow cytometry (FCM) assay. Testosterone concentration was determined by ELISA. Moreover, histological assessment of testicles in mice was performed by using HE staining and the TUNEL assay was used to determine apoptosis. We found that the lncRNA XIST was downregulated in the testicular tissues of LOH patients and mice and in H2O2-induced TM3 cells. XIST siRNA significantly promoted apoptosis, enhanced Caspase3 activity and reduced testosterone levels in H2O2-stimulated TM3 cells. Further studies showed that the miR-145a-5p inhibitor reversed the effect of XIST-siRNA on H2O2-induced Leydig cell apoptosis. MiR-145a-5p negatively regulated SIRT1 expression, and SIRT1-siRNA reversed the effects of the miR-145a-5p inhibitor on H2O2 stimulated TM3 cells. The in vivo experiments indicated that silencing of the lncRNA XIST aggravated LOH symptoms in mice. Inhibition of lncRNA XIST induces Leydig cell apoptosis through the miR-145a-5p/SIRT1 axis in the progression of LOH.

Abstract
Endometriosis (EMS) is a chronic inflammatory disorder of high incidence that causes serious reproductive consequences. High estrogen production is a consistently observed endocrine feature of EMS. The present study aims to probe the molecular mechanism of G protein-coupled estrogen receptor 1 (GPER) in the invasion and migration of ectopic endometrial stromal cells (Ect-ESCs) and provides a new rationale for EMS treatment. Eutopic and ectopic endometrial tissues were collected from 41 EMS patients, and primary ESCs were separated. GPER, miR-16-5p, and miR-103a-3p levels in cells and tissues were determined by qRT-PCR or Western blot assay. Cell viability, proliferation, invasion, and migration were evaluated by CCK-8, colony formation, and Transwell assays. The upstream miRNAs of GPER were predicted by databases, and dual-luciferase assay was performed to validate the binding of miR-16-5p and miR-103a-3p to GPER 3'UTR. GPER was highly expressed in EMS tissues and Ect-ESCs. Inhibition of GPER mitigated the proliferation, invasion, and migration of Ect-ESCs. GPER was regulated by miR-16-5p and miR-103a-3p. Overexpression of miR-16-5p and miR-103a-3p negatively regulated GPER expression and inhibited the invasion and migration of Ect-ESC. In conclusion, GPER promoted the invasion and migration of Ect-ESCs, which can be reversed by upstream miR-16-5p and miR-103a-3p.
