OBJECTIVE: To investigate the expression of steroidogenic factor 1 (SF-1) in eutopic endometrium, ovarian endometriosis (EM) and adenomyosis. METHODS: From Jan. 2008 to Dec. 2010, 30 patients with both ovarian endometriotic cysts and adeno…
UNLABELLED: Endometriosis is an estrogen-dependent disease. Steroidogenic factor 1 (SF-1), a transcription factor, is essential for the activation of multiple steroidogenic genes for estrogen biosynthesis in endometriosis-derived stromal ce…
Estradiol (E2) stimulates the growth and inflammation in the ectopic endometriotic tissue that commonly resides on the pelvic organs. Several clinical and laboratory-based observations are indicative of resistance to progesterone action in …
Loss of progesterone signaling in the endometrium may be a causal factor in the development of endometriosis, and progesterone resistance is commonly observed in women with this disease. In endometriotic stromal cells, the levels of progest…
OBJECTIVE: To determine whether the expression of leukemia inhibitory factor during the implantation window in endometrial tissue and uterine flushing fluid of patients with adenomyosis differs from that of healthy fertile women. DESIGN: E…
Endometriosis is a common and chronic disease characterized by persistent pelvic pain and infertility. Estradiol is essential for growth and inflammation in endometriotic tissue. The complete cascade of steroidogenic proteins/enzymes includ…
Steroid receptors in the stromal cells of endometrium and its disease counterpart tissue endometriosis play critical physiologic roles. We found that mRNA and protein levels of estrogen receptor 2 (ESR2) were strikingly higher, whereas leve…
CONTEXT: Endometriosis is an estrogen-dependent disease. Steroidogenic factor-1 (SF-1), a transcriptional factor essential for activation of multiple steroidogenic genes for estrogen biosynthesis, is undetectable in normal endometrial strom…
Local estrogen biosynthesis is a major factor in the pathogenesis of endometriosis. Aberrant expression of steroidogenic acute regulatory protein (StAR) and aromatase in endometriotic tissue leads to an up-regulation of estrogen production.…
