BACKGROUND: While heavy menstrual bleeding (HMB) is a prevalent symptom among women with abnormal uterine bleeding caused by endometrial disorder (AUB-E) seeking gynecologic care, the primary endometrial disorder remains poorly understood. …

BACKGROUND: The polycystic ovary syndrome (PCOS) is the most common endocrine associated with insulin resistance, even in the absence of overweight. The global lipid profile of the follicular fluid in PCOS with normal weight as yet has not …

Studies have reported that non-receptive endometrium or abnormal decidualization was closely related to recurrent implantation failure (RIF). MLL1 is a histone H3 lysine 4 trimethylation (H3K4me3) transferase that regulates the transcriptio…

BACKGROUND: As a classic innate immunity pathway, Toll-like receptor 4 (TLR4) signaling has been intensively investigated for its function of pathogen recognition. The receptor is located not only on immune cells but also on sensory neurons…

The aberrant histone methylation patterns contribute to the pathogenesis of endometriosis (EM). Mixed lineage leukemia 1 (MLL1), a histone methyltransferase, is crucial for gene expression by catalyzing the trimethylation of histone 3 lysin…

Dysregulation of microRNAs in endometrial cells plays a pivotal role in the pathogenesis of endometriosis (EM). This study aims to investigate the implication of aberrant miR-202-3p expression in EM and the underlying mechanisms. We demonst…

OBJECTIVE: To investigate the effect of seasons on the incidence of high risk of ovarian hyperstimulation syndrome (OHSS) after in oocyte retrieval in patients with polycystic ovarian syndrome (PCOS) and to establish a nomogram to predict t…

PURPOSE: To explore the mechanism of levonorgestrel (LNG)-ameliorating adenomyosis through long non-coding RNA H19 (lncRNA H19)/miR-17/Toll-like receptor 4 (TLR4) pathway. PATIENTS AND METHODS: A total of 71 cases of adenomyosis and 54 cas…

OBJECTIVES: Elevated concentrations of numerous molecules have been reported in the peritoneal cavity of women with endometriosis. Until now, no factor proved sufficiently specific to endometriosis. We aimed to investigate several biomarker…

Recurrence of endometriosis after surgery constitutes a serious challenge. Whether there is an evolution of lesion subtypes with each recurrence and whether certain lesions subtypes tend to recur faster than others is not adequately address…

Gonadotrophin-releasing hormone (GnRH), also known as luteinizing hormone-releasing hormone, is the main regulator of the reproductive system, acting on gonadotropic cells by binding to the GnRH1 receptor (GnRH1R). The GnRH-GnRH1R system is…

Female animals living in the Qinghai-Tibet Plateau have lower ovulation rates because of the hypoxic environment, however, the mechanism of hypoxia on animal follicles is unclear. In this study, the effects of hypoxia on bovine follicles we…

Background: Findings by epidemiologic studies on menopausal hormone replacement therapy (HRT) and the risk of ovarian cancer are inconsistent. This study aimed to assess the association of menopausal HRT with the risk of ovarian cancer by h…

The detailed pathogenesis of endometriosis remains largely unclear despite decades of research. Recent studies have demonstrated that miRNAs plays an important role in endometriosis. The expression of miR-142-3p was decreased in ectopic end…

In this pictorial review, MR imaging findings of deep infiltrating endometriosis (DIE) are illustrated together with surgical correlation. DIE can appear as irregular nodules or plaques with similar signal intensity to muscle on both T1-wei…

Tumor derived human growth hormone (hGH) has been implicated in cancer development and progression. However, the specific functional role of autocrine/paracrine hGH in colorectal cancer (CRC) remains largely to be determined. Herein, we dem…

Pediatric cancer (PC), that is cancer occurring in children, is the leading cause of death among children worldwide, with an incidence of 175,000 per year. Elucidating the genetic abnormalities and underlying cellular mechanisms may provide…

AIMS: Musashi-1, a RNA-binding protein, is suggested to be a cancer stem cell-related marker; its high level of protein expression is reported to be associated with high histological grade in some tumors. The aim of this study was to invest…

Sponsored by the New York Academy of Sciences and Cincinnati Children's Hospital Medical Center, with support from the National Institute of Environmental Health Sciences (NIEHS), the National Institute on Drug Abuse (NIDA), and Life Techno…

OBJECTIVE: This descriptive study assessed the rate and costs of surgical procedures among newly diagnosed endometriosis patients. METHODS: Utilizing the Medstat MarketScan database, commercially insured women aged 18-45 with endometriosis…

MicroRNAs (miRNAs) are small non-coding RNAs that mediate post-transcriptional gene silencing. Over 700 human miRNAs have currently been identified, many of which are mutated or de-regulated in diseases. Here we report the identification of…

OBJECTIVE: To study the function of heparanase gene in the pathogenesis of endometriosis. METHODS: In situ hybridization method was used to examine the heparanase mRNA expression in the eutopic and ectopic endometrium of patients with endo…
