2013
In stromal cells of endometriosis, marked levels of aromatase P450 (P450arom) mRNA and activity are present and can be vigorously stimulated by (Bu) 2cAMP or PGE 2 to give rise to physiologically significant estrogen biosynthesis. Since eut…

We previously demonstrated that 17 � hydroxysteroid dehydrogenase type 2, the enzyme that inactivates estradiol to estrone, is expressed in luteal eutopic endometrium in response to progesterone but not in simultaneously biopsied peritoneal…

review
2000
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 …

ObjectiveAlthough an association between dioxin exposure and endometriosis has been proposed, the effects of this environmental toxin on human endometriosis are not known. To understand the potential underlying molecular mechanisms we studi…

ObjectiveTo provide a clinically useful model illustrating the molecular aberrations affecting estrogen biosynthesis and metabolism in endometriosis and to discuss the therapeutic role of aromatase inhibitors.DesignLiterature review.Result(…
review
1999
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 …

1998
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…

The aim of this study was to characterize the appearance of the vascular pattern of endometriomas in terms of color Doppler and to verify the role of Doppler flow indices in differentiating endometriomas from other pelvic masses. Twenty pat…
