Abstract

Using feminizing adrenal neoplastic gland (FANG) cells we showed that hPRL stimulated cGMP biosynthesis. Also we could clearly demonstrate a stimulatory effect of db-cGMP plus theophylline on estrogen production without concomitant stimulation of cell growth. These findings indicate that a stimulatory effect of hPRL on estrogen biosynthesis by Fang-8 cells may act via increased cGMP concomitant with depressed CAMP.
