Conversion of C19 steroids to estrogens is catalyzed by aromatase in human ovary, placenta and extraglandular tissues such as adipose tissue, skin and the brain. Aromatase activity is not detectable in normal endometrium. In contrast, aroma…
ObjectiveTo quantify and compare messenger RNA (mRNA) levels of ER-alpha and ER-beta among ovarian endometriotic cysts and red and black peritoneal endometriotic lesions.DesignProspective study.SettingUniversity hospital.Patient(s)Patients …
In contrast to normal endometrium, the expression of aromatase is aberrant in endometriosis and is stimulated by prostaglandin E2 (PGE2). This results in local production of estrogen, which induces PGE2 formation and establishes a positive …
ObjectiveTo evaluate the expression of estrogen receptor (ER)-alpha and ER-beta messenger RNA (mRNA) in ovarian endometriosis.DesignProspective study.SettingUniversity hospital.Patient(s)Patients with endometriosis and patients with uterine…
Conversion of C(19) steroids to estrogens is catalyzed by aromatase in human ovary, placenta and extraglandular tissues such as adipose tissue, skin and the brain. Aromatase activity is not detectable in normal endometrium. In contrast, aro…
Although treatment of one unusually aggressive case of postmenopausal endometriosis with an aromatase inhibitor has been strikingly successful, large clinical trials are required to establish whether aromatase inhibitors will have a signifi…
Cessation of ovarian estrogen secretion is the key event during the climacteric. An enzyme termed aromatase in a number of human tissues and cells, including ovarian granulosa cells, the placental syncytiotrophoblast, adipose and skin fibro…
Estrogen is the most important known factor that stimulates the growth of endometriosis. Estrogen delivery to endometriotic implants was classically viewed to be only via the circulating blood in an endocrine fashion. We recently uncovered …
Aberrant aromatase expression in stromal cells of endometriosis gives rise to conversion of circulating androstenedione to estrone in this tissue, whereas aromatase expression is absent in the eutopic endometrium. In this study, we initiall…
ObjectiveTo treat an unusually aggressive case of recurrent postmenopausal endometriosis.DesignCase report.SettingUniversity of Texas Southwestern Medical Center (Dallas, Texas).Patient(s)A 57-year-old woman who presented with recurrent sev…
