17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) is an enzyme that catalyzes NADPH-dependent reduction of the weak estrogen, estrone, into the most potent estrogen, estradiol, which exerts proliferative effects via the estrogen receptors. Overexpression of 17β-HSD1 in estrogen-responsive tissues is related to
