Regulation of 11beta-hydroxysteroid dehydrogenase type II in rat adrenocortical cells.
The regulation of 11beta-hydroxysteroid dehydrogenase type II (11beta-HSD2) gene expression was studied in primary cultures of rat adrenocortical cells. The protein kinase A (PKA) pathway agonists forskolin, dibutyryl cAMP and ACTH caused a 5-10 fold increase in 11beta-HSD2 mRNA as determined by semiquantitative PCR. The effect of forskolin could be partially inhibited by the addition of the phorbol ester TPA, an activator of the protein kinase C (PKC) pathway. The increase in mRNA encoding 11beta-HSD2 was accompanied by increased synthesis of 11beta-HSD2 as measured by immunoprecipitation of labeled protein. It is concluded that both the PKA and PKC pathways are involved in the regulation of rat adrenal 11beta-HSD2 gene expression.
