Aromatase Expression in Endometriosis and Its Significance

Endometriosis

Abstract

Endometriosis is a chronic inflammatory disease frequently observed in the ovary, pelvic peritoneum, and rectovaginal septum. The growth and progression of an endometriotic lesion depends on a sex steroid, estrogen. Aromatase, a key enzyme in estrogen biosynthesis, is highly expressed in the endometriotic tissue, resulting in in situ production of estrogen that, in addition to endocrine estrogen from the ovary, may contribute to the etiology and progression of endometriosis. The aberrant expression of aromatase together with the elevated expression of 17β-hydroxysteroid dehydrogenase type 1 and the absence of 17β-hydroxysteroid dehydrogenase type 2 observed in the endometriotic tissue would contribute to an increase in the tissue concentration of estrogen. Aromatase expression is regulated at multiple levels, from the transcription of CYP19A1 and epigenetic codes to posttranslational modification and degradation of the protein. Among the multiple promoters of CYP19A1, the most proximal promoter PII is the most active in endometriosis and is regulated by cAMP, prostaglandin E2, steroidogenic factor-1, and possibly the end product estrogen. Hypomethylation of CpG islands on CYP19A1 observed in the endometriotic tissue may contribute to the upregulation of aromatase expression.

Similar to spontaneous menopause, inhibition of in situ estrogen biosynthesis may regress endometriosis. The use of aromatase inhibitors (AIs), which selectively inhibit aromatase activity in human tissues, is a possible treatment for inhibiting local estrogen biosynthesis in endometriosis. AIs have been used as monotherapy or in combination therapies with progestins, oral contraceptive pills, and gonadotropin-releasing hormone agonists to reduce endometriosis-related pain in premenopausal women.
