BACKGROUND: To investigate whether polymorphisms of CYP17 and CYP19 genes are associated with the risk of endometriosis, we analysed the frequency and distribution of a single nucleotide polymorphism at the 5' untranslated region of the CYP…

Endometriosis, defined as the presence of endometrial glands and stroma outside of the uterine cavity, develops mostly in women of reproductive age and regresses after menopause or ovariectomy, suggesting that the growth is estrogen-depende…

An immunohistochemical study was made of a case of serous cystadenocarcinoma that had been shown to have arisen from ovarian endometriosis. Aromatase cytochrome P450 (P450arom), an enzyme responsible for estrogen biosynthesis, was localized…

Endometriosis, adenomyosis and leiomyomata develop in women of reproductive age and regress after menopause or ovariectomy, suggesting that they grow in an oestrogen-dependent fashion. We investigated whether polymorphism in the oestrogen r…

Leptin is secreted by adipocytes and regulates appetite through interaction with hypothalamic leptin receptors (OB-R). Accumulated evidence shows that leptin is involved in the stimulation of reproductive functions and that local expression…

In the human endometrium, inactivation of 17beta-estradiol to estrone is catalyzed by 17beta-hydroxysteroid dehydrogenase type 2 (17betaHSD2). Previous studies have shown that the 17betaHSD2 activity in the endometrium is elevated during th…

Endometriotic implants, like other estrogen-dependent tumors, contain both estrogen receptors and aromatase cytochrome P450 (P450arom), suggesting that at a local level, endometriotic implants produce estrogens, which may be involved in tis…

To determine whether local estrogen production takes place in endometriotic or adenomyotic tissues, in eutopic endometrium from patients with endometriosis or adenomyosis, and in normal endometrium, tissue specimens were examined by immunoh…

The development of human uterine estrogen-dependent tumors is considered to be closely related to estrogen biosynthesis. This study examined whether or not 14 alpha-hydroxy-4-androstene-3,6,17-trione (14 alpha-OHAT), a new 4-androstene-3, 1…
