Five immune-related genes as diagnostic markers for endometriosis and their correlation with immune infiltration.

Endometriosis (EMS) is a chronic disease that can cause dysmenorrhea, chronic pelvic pain, and infertility, among other symptoms. EMS diagnosis is often delayed compared to other chronic diseases, and there are currently no accurate, easily accessible, and non-invasive diagnostic tools. Therefore, it is important to elucidate the mechanism of EMS and explore potential biomarkers and diagnostic tools for its accurate diagnosis and treatment.

Role of Pyroptosis in Gynecological Oncology and Its Therapeutic Regulation.

With the continuous advances in molecular biotechnology, many new cell death methods have been discovered. Pyroptosis is a programmed cell death process that differs from apoptosis and autophagy in cell morphology and function. Compared with apoptosis and autophagy, pyroptosis is primarily mediated by intracellular inflammasome and gasdermin D of the gasdermin protein family and involves the release of numerous inflammatory factors.

GnRH agonist treatment regulates IL-6 and IL-11 expression in endometrial stromal cells for patients with HRT regiment in frozen embryo transfer cycles.

To evaluate the effect of gonadotropin-releasing hormone agonist (GnRHa) pretreatment time on clinical outcomes of patients who underwent endometrial preparation in HRT cycles and the molecular mechanism in frozen-thawed embryo transfer (FET) cycles, we retrospectively chose 1143 cycles and separated four groups. Endometrial tissues were collected from 44 patients who were cancelled on the day of embryo transfer (there were 10 patients refused to collect endometrium) and were tested for endometrial receptivity marker mRNA and miR-124-3p expression. Furthermore, endometrial stromal cells (ESCs) were transfected to investigate the molecular mechanism.

Gut Microbiota in Patients with Polycystic Ovary Syndrome: a Systematic Review.

Polycystic ovary Syndrome (PCOS) is one of the most popular diseases that cause menstrual dysfunction and infertility in women. Recently, the relationships between the gastrointestinal microbiome and metabolic disorders such as obesity, type 2 diabetes and PCOS have been discovered. However, the association between the gut microbiome and PCOS symptoms has not been well established.

Curcusone C induces apoptosis in endometrial cancer cells via mitochondria-dependent apoptotic and ERK pathway.

Objective: Jatropha curcashas been used in traditional medicine in Africa to treat cancer for thousands of years. This study aimed to examine the anti-endometrial cancer effect of Curcusone C, a naturally occurring rhamnofolane diterpene, isolated from J. curcas and reveal its molecular mechanism of action.

Ca2+ channel subunit a 1D inhibits endometriosis cell apoptosis and mediated by prostaglandin E2.

Objectives: Endometriosis is considered as a chronic pelvic inflammatory disease and prostaglandin E2(PGE2) (a kind of the inflammatory cytokines) was increased in the endometriosis patient's peritoneal fluid . Ca2+ signal and Ca2+ channels play an important role in cell apoptosis. This study was to explore the L-type calcium channel (Cav1.

The influence of l-carnitine on the expression of miRNAs in asthenospermia spermatozoa and the network regulation of the associated molecules.

l-carnitine is a natural compound that is indispensable for energy metabolism in mammals. The efficiency and safety of l-carnitine in improving sperm activity, enhancing epididymal function and treating male infertility has been widely acknowledged by clinicians. CircRNAs can regulate gene expression at the transcriptional or post-transcriptional level by serving as a molecular sponge of miRNAs with miRNA response elements.

Autologous peripheral blood mononuclear cells intrauterine instillation to improve pregnancy outcomes after recurrent implantation failure: a systematic review and meta-analysis.

Purpose: Recurrent implantation failure (RIF) is a common cause of disappointment and a big challenge after assisted reproduction technology treatments. The objective of this study was to evaluate the existing literature to explore whether peripheral blood mononuclear cells' (PBMCs) instillation could improve pregnancy outcomes among patients with RIF.

Methods: We conducted a comprehensive search including PubMed, EMBASE, Cochrane library and various databases in China.

Liver X Receptor Gene Expression is Enhanced in Children with Obstructive Sleep Apnea-Hyperpnoea Syndrome and Cyclooxygenase-2 (COX-2) is Correlated with Severity of Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS).

BACKGROUND Liver X receptor (LXR) is a nuclear receptor presenting in macrophages; it works indispensably in lipid metabolism control and also negatively regulates the expression of inflammatory genes in macrophages. There are many LXR-related studies in adults with metabolic syndrome but rare reports in obese children with obstructive sleep apnea-hypopnea syndrome (OSAHS). The aim of this study was to investigate the expression of LXR, cholesterol ester transfer protein (CETP), and cyclooxygenase-2 (COX-2) genes in obese children with OSAHS compared with obese children without OSAHS and non-obese children.
