Endometriosis is a common gynecological disease, which is defined as the growth of endometrial tissues outside the uterine cavity. It often causes dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility in reproductive-age women. Ho…

STUDY QUESTION: How does hypoxia-mediated downregulation of chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) promote angiogenesis in endometriosis? SUMMARY ANSWER: Suppression of COUP-TFII by hypoxia stimulates angio…

BACKGROUND: Endometriosis is one of the most common gynecological diseases that greatly compromises the quality of life in affected individuals. A growing body of evidence shows that the remodeling of retrograde endometrial tissues to the e…

PROBLEM: How does hypoxia-mediated downregulation of dual-specificity phosphatase-2 (DUSP2) promote the development of endometriotic lesions? METHOD OF STUDY: The levels of IL-6 and DUSP2 were assessed in eutopic stromal cells with DUSP2 k…

Endometriosis is a highly prevalent gynaecological disease that severely reduces women's health and quality of life. Ectopic endometriotic lesions have evolved mechanisms to survive in the hypoxic peritoneal microenvironment by regulating t…

STUDY HYPOTHESIS: DNA methylation is regulated by hypoxia in endometriosis. STUDY FINDING: Hypoxia causes global hypomethylation through AU-rich element binding factor 1 (AUF1)/microRNA-148a (miR-148a)-mediated destabilization of DNA methy…

Endometriosis is one of the most common gynecological diseases that significantly reduce the life quality of affected women. Research results from the past decade clearly demonstrated that aberrant production of estrogen and cyclooxygenase-…

STUDY QUESTION: How does hypoxia-mediated down-regulation of dual specificity phosphatase-2 (DUSP2) promote endometriotic lesion development? SUMMARY ANSWER: Inhibition of DUSP2 by hypoxia enhances endometriotic lesion growth via promoting…

CONTEXT: Endometriosis is one of the most common gynecological diseases in women with a prevalence rate of approximately 10%. Chronic pelvic inflammation has been observed in patients with endometriosis and is associated with disease severi…

STUDY QUESTION: Is annexin A2 involved in the reduced phagocytic ability of macrophages in endometriosis? SUMMARY ANSWER: Data from women with endometriosis and a murine model of the disease show that expression of annexin A2 in peritoneal…

OBJECTIVE: Endometriosis is an estrogen-dependent disease. The aim of this study was to evaluate the different expression of estrogen receptors (ER) and its relation to hypoxia inducible factor-1α (HIF-1α) in stromal cells from women with e…

CONTEXT: Aberrant activation of MAPK has been implicated to play important roles in pathological processes of endometriosis. However, how MAPK are constitutively activated in endometriotic tissues remains largely unknown. microRNA are small…

OBJECTIVE: The aim of this study was to investigate simultaneous laparoscopy in endometriotic women with infertility undergoing in vitro fertilization (IVF). MATERIALS AND METHODS: Forty-seven infertile patients with endometriosis were enr…

Endometriosis is one of the most common gynaecological diseases that significantly reduces the life qualify of affected women and their families. Aberrant expression of cyclooxygenase-2 (COX-2), and thus over-production of prostaglandin E(2…

Endometriosis is the primary cause of infertility in women, with a prevalence rate ranging from 5% to 10%. Women with endometriosis suffer from symptoms such as chronic pelvic pain, dysmenorrhea and dyspareunia, which significantly reduce t…

Endometriosis, defined as the growth of endometrial tissues outside of the uterine cavity, is a severe and complex disease affecting more than 10% of women. The aetiology of endometriosis is unclear but immune dysfunction might be an import…

Dysfunction in macrophage-mediated phagocytosis of aberrant cells that undergo retrograde transport to the peritoneal cavity is considered an important factor in the development of endometriosis. However, the mechanisms responsible for the …

PROBLEM: The expression of cyclooxygenase (COX)-2 is considered as a marker of macrophage activation and has been implicated in the development of endometriosis. Leptin is an immunomodulator, which may also affect the development of endomet…

Aberrant expression of the steroidogenic acute regulatory (StAR) protein in human endometriotic stromal cells plays an important role in the development of endometriosis. Prostaglandin E(2) (PGE(2)) is a potent inducer of StAR expression in…

Elevated expression of leptin in endometriotic tissue results in an increase in stromal cell proliferation and may contribute to the development of endometriosis. However, the underlying mechanism responsible for aberrant expression of lept…

Endometriosis is considered to be a polygenic disease with a complex, multifactorial aetiology that affects about 10% of women in the reproductive age. Women with endometriosis have symptoms that include chronic pelvic pain, dysmenorrhoea a…

Aberrant production of cyclooxygenase-2 (COX-2) plays pivotal roles in many pathological processes including tumorigenesis and endometriosis, although the underlying mechanism remains obscure. Herein we report evidence to demonstrate that C…

Decreased phagocytotic ability of macrophages has been reported to be associated with the severity of endometriosis, although the underlying mechanism remains uncharacterized. Expression and secretion of matrix metalloproteinase (MMP)-9 by …
