Androgens Modulate Rat Granulosa Cell Steroidogenesis.

ABSTRACT: Paracrine interactions between ovarian theca-interstitial cells (TICs) and granulosa cells (GCs) play an important role in the regulation of follicular steroidogenesis. Androgens serve as substrates for aromatization as well as affect GC function. This study evaluated the effects of co-culture of GC with TICs and the role of testosterone (T) and 5-alpha-dihydrotestosterone (DHT), and estradiol (E2) in modulation of GC expression of genes involved in the production of progesterone: 3β-hydroxysteroid dehydrogenase/Δ^5-4 isomerase (Hsd3b) and cholesterol side-chain cleavage (Cyp11). GCs obtained from immature Sprague-Dawley rats and were cultured in chemically defined media without or with TICs, DHT, or T. Hsd3b and Cyp11 transcripts were analyzed by qt-PCR. Co-culture of GCs with T
