Aberrant activation of signal transducer andactivatorof transcription-3 (STAT3) signaling in endometriosis

CONTEXT: Endometriosis results in aberrant gene expression in the eutopic endometrium (EuE) and subsequent progesterone resistance. MicroRNA (miR) microarray data in a baboon model of endometriosis showed an increased expression of miR-29c.…

Endometriosis is a major cause of chronic pelvic pain and infertility. Activation of STAT3 appears central to the inflammatory phenotype of eutopic endometrium in women with endometriosis. However, the molecular mechanism by which this occu…

AT-rich interactive domain 1A gene (ARID1A) loss is a frequent event in endometriosis-associated ovarian carcinomas. Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus, and 50 % of wome…

OBJECTIVE: To determine the impact of endometriotic lesion removal on local and systemic inflammation. DESIGN: Multiplex cytokine analysis on samples from endometriosis patients before surgery, 2 weeks after surgery, and 3 months after sur…

STUDY QUESTION: Are STAT3 signaling molecules differentially expressed in endometriosis? SUMMARY ANSWER: Levels of phospho-STAT3 and HIF1A, its downstream signaling molecule, are significantly higher in eutopic endometrium from women with …

AT-rich interactive domain 1A gene (ARID1A) loss is a frequent event in endometriosis-associated ovarian carcinomas. Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus, and 50% of women…

C-X-C ligand 13 (CXCL13), a regulator of mucosal immunity, is secreted by human endometrial epithelium and may be involved in embryo implantation. However, cyclic expression of human endometrial CXCL13 in health and disease is not well stud…

Endometriosis is a chronic, inflammatory disease characterized by the growth of endometrial tissue in aberrant locations outside the uterus. Neoangiogenesis or establishment of new blood supply is one of the fundamental requirements of endo…

PROBLEM: Uterine natural killer cells (uNK) have been thought to play a key role in endometriosis and infertility. We investigated the expression of CD56, CD16, and NKp46 in endometrial tissues from 61 women with unexplained recurrent pregn…

Purpose The aim of this study was to investigate if there is a higher incidence of endometriosis in patients with polycystic ovary syndrome (PCOS), compared with normal fertile controls. Material and methods Women with PCOS according to Rot…

Endometriosis, defined as the presence of endometrial cells outside of the uterine cavity, is a major cause of infertility and pelvic pain, afflicting more than 10% of reproductive age women. Endometriosis is a chronic inflammatory disease …

CONTEXT: Endometriosis is a common gynecological disease affecting one in 10 women of reproductive age and is a major cause of pelvic pain and impaired fertility. Endometrial stromal cells of women with endometriosis exhibit a reduced respo…

Endometriosis affects up to 10% of women of reproductive age and 176 million women worldwide. The prevalence in women with infertility is between 30% and 50% but may be higher in women with pelvic pain, interstitial cystitis, or irritable b…

Aims The aim of this study was to identify whether endometriosis is a progressive disease with age, and to review the literature on this topic. Material and methods The incidence of endometriosis in a cohort of 500 women who underwent lapar…

STUDY QUESTION: Are the transmembrane mucins, MUC1, MUC4 and MUC16, differentially expressed in endometriosis compared with normal endometrium? SUMMARY ANSWER: This study revealed that transmembrane mucin expression does not vary significa…

BACKGROUND: 'Omics' high-throughput analyses, including genomics, epigenomics, transcriptomics, proteomics and metabolomics, are widely applied in human endometrial studies. Analysis of endometrial transcriptome patterns in physiological an…

Embryo implantation is regulated by an inflammatory process in response to sequential exposure to estrogen and progesterone, followed by resolution and repair. The actions of estrogen and progesterone on these inflammatory processes are tig…

Cytokines present within the environment of endometriosis are believed to contribute to the pathogenesis of the disease by promoting inflammatory conditions surrounding the implantation of endometriotic lesions. Interleukin‐17A is a member …
