Endometriosis is a common gynecological disease characterized by diminished apoptosis, sustained ectopic survival of dysfunctional endometrial cells. Hypoxia has been implicated as a crucial microenvironmental factor that contributes to end…
BACKGROUND: MicroRNAs (miRNAs) regulate the expression of genes involved in various cellular functions related to metabolism, inflammation, and reproduction. This study evaluated the effects of sex hormones and obesity on the expression of …
Endometriosis is a benign gynecological disease that shares some characteristics with malignancy like migration and invasion. It has been reported that both hypoxia-inducible factor-1α (HIF-1α) and autophagy were upregulated in ectopic endo…
STUDY HYPOTHESIS: Do estrogen and Wnt/β-catenin signaling promote vascular endothelial growth factor (VEGF) expression in endometriosis and how? STUDY FINDING: 17β-Estradiol (E2)-drives β-catenin triggered up-regulation of VEGF in effector…
STUDY QUESTION: How does hypoxia promote growth of lesions in the development of endometriosis? SUMMARY ANSWER: Hypoxia induces the epithelial-mesenchymal transition (EMT) of endometrial cells, resulting in changes in cellular characterist…
Extracellular matrix remodeling is necessary for ectopic endometrium implantation. Many studies have shown an increased expression of matrix metalloproteinase 9 (MMP9) in the ectopic endometrium of endometriosis. However, the signaling path…
The recent characterization of stem/progenitor cells in the endometrium has shed new light for pathogenesis of endometriosis. The present study was undertaken to investigate the role of Notch1, known as a cell fate regulator, in the mechani…
Endometriosis is an estrogen-dependent disease that involves the adhesion, invasion, and angiogenesis of endometrial tissues outside of the uterine cavity. We hypothesized that a link exists between estrogen and beta-catenin (β-catenin) sig…
Endometriosis is a common benign gynecological disease defined as the presence of endometrial tissue outside the uterine cavity. The aim of this study was to identify the molecular mechanism underlying hypoxia-induced increases in invasive …
