title: Effects of ACTH and cytokines on dehydroepiandrosterone sulfotransferase messenger RNA in human adrenal cells.
abstract: Dehydroepiandrosterone sulfate (DS) is the major adrenal androgen produced in the fetal and adult human; its formation is dependent upon the action of dehydroepiandrosterone sulfotransferase (DST). Since the factors that regulate DST are poorly characterized, we investigated the effects of ACTH, which stimulates DS production, and the cytokines transforming growth factor-beta (TGF-beta), and tumor necrosis factor-alpha (TNF-alpha) , both of which are inhibitory to adrenal steroidogenesis, on cultured human fetal adrenal cells. Cellular levels of DST mRNA were increased in a dose dependent fashion in response to ACTH; DST mRNA was less responsive to ACTH stimulation than was 17 hydroxylase (CYP 17) mRNA. The stimulatory effects of ACTH on DST mRNA levels were blunted by both TGF-beta and TNF-alpha; the inhibitory effects of TNF-alpha on DST mRNA were more striking than were those on CYP 17 mRNA. These data suggest that DS production can be altered by several agents acting on the DST gene.
