Endometriosis is a chronic, estrogen-dependent condition affecting over 190 million women globally, characterized by the ectopic presence of endometrial-like tissue that leads to inflammation, pain, and infertility. Despite its prevalence, …

Existing medical treatments for endometriosis-related pain are often ineffective, underscoring the need for new therapeutic strategies. In this study, we applied a computational drug repurposing pipeline to stratified and unstratified disea…

Endometriosis is a leading cause of pain and infertility affecting millions of women globally. Herein, we characterize variation in DNA methylation (DNAm) and its association with menstrual cycle phase, endometriosis, and genetic variants t…

Endometriosis is a common condition associated with debilitating pelvic pain and infertility. A genome-wide association study meta-analysis, including 60,674 cases and 701,926 controls of European and East Asian descent, identified 42 genom…

Abstract Endometriosis is a common, inflammatory pain disorder comprised of disease in the pelvis and abnormal uterine lining and ovarian function that affects ∼200 million women of reproductive age worldwide and up to 50% of those with pel…

STUDY QUESTION: Is circulating cell-free DNA (cirDNA) from the endometrium elevated during menstruation and in endometriosis? SUMMARY ANSWER: Endometrial cirDNA does not increase during menstruation and is not elevated in endometriosis. W…

Abstract Endometriosis is a leading cause of pain and infertility affecting millions of women globally. Identifying biologic and genetic effects on DNA methylation (DNAm) in endometrium increases understanding of mechanisms that influence g…

The uterine lining (endometrium) exhibits a pro-inflammatory phenotype in women with endometriosis, resulting in pain, infertility, and poor pregnancy outcomes. The full complement of cell types contributing to this phenotype has yet to be …

Research questionDo women with laparoscopically confirmed endometriosis have higher plasma concentrations of circulating cell-free DNA (cirDNA) than those without endometriosis?DesignProspective study of women aged 18-45 years undergoing be…

Abstract The uterine lining (endometrium) exhibits a pro-inflammatory phenotype in women with endometriosis, resulting in pain, infertility, and poor pregnancy outcomes. The full complement of cell types contributing to this phenotype has y…

The etiology and pathogenesis of endometriosis are complex with both genetic and environmental factors contributing to disease risk. Genome-wide association studies (GWAS) have identified multiple signals in the estrogen receptor 1 (ESR1) r…

Progestins are widely used for the treatment of gynecologic disorders and alone, or combined with an estrogen, are used as contraceptives. While their potencies, efficacies and side effects vary due to differences in structures, doses and r…

STUDY QUESTION: Do seminal plasma (SP) and its constituents affect the decidualization capacity and transcriptome of human primary endometrial stromal fibroblasts (eSFs)? SUMMARY ANSWER: SP promotes decidualization of eSFs from women with …

Programmed cellular responses to cycling ovarian-derived steroid hormones are central to normal endometrial function. Abnormalities therein, as in the estrogen-dependent, progesterone-"resistant" disorder, endometriosis, predispose to infer…

ObjectiveTo phenotype transcriptomically M1 macrophages (Mϕ1) and M2 macrophages (Mϕ2) in the endometrium of women with endometriosis.DesignProspective experimental study.SettingUniversity research laboratory.Patient(s)Six women with endome…

BACKGROUND: Endometriosis, a common oestrogen-dependent inflammatory disorder in women of reproductive age, is characterized by endometrial-like tissue outside its normal location in the uterus, which causes pelvic scarring, pain and infert…

Uterine fibroids are a common finding in infertility patients. Impaired implantation and decidualization have been proposed to contribute to compromised fertility. Data are limited on the endometrial transcriptome from subjects with uterine…

Endometriosis is an estrogen-dependent, progesterone-resistant disorder largely derived from retrograde transplantation of menstrual tissue/cells into the pelvis, eliciting an inflammatory response, pelvic pain, and infertility. Eutopic end…

Human endometrium undergoes cyclic regeneration involving stem/progenitor cells, but the role of resident endometrial mesenchymal stem cells (eMSC) as progenitors of endometrial stromal fibroblasts (eSF) has not been definitively demonstrat…

SYSTEMIC AND FOLLICULAR OXIDATIVE STRESS IN INFERTILE WOMEN WITH ENDOMETRIOSIS UNDERGOING CONTROLLED OVARIAN STIMULATION FOR ICSI: IS THERE A ROLE IN THE ETIOPATHOGENESIS OF INFERTILITY? M. G. Da Broi, F. O. Albuquerque, A. Z. de Andrade, R…
