Abstract

Reduction of dihydrotestosterone into 5 alpha-androstan-3 alpha, 17 beta diol by 3 alpha hydroxysteroid dehydrogenase was studied in human cultured skin fibroblasts. Characterization of the 3 alpha diol was performed by gas-liquid chromatography coupled with mass spectrometry. Sex skin fibroblasts enzyme has the same Km (9.10 X 10(-6) M) as that of non sex skin fibroblasts (8.75 X 10(-6) M). On the other hand, reduction of DHT is 3 times higher in sex skin fibroblasts (Vmax = 223.9) than in non sex skin fibroblasts (Vmax = 87.9). Thus, human culturel fibroblasts appear again to be an useful tool for the study of a key-enzyme of androgen metabolism in target cells.
