Abstract

Primary, monolayer cultures of bovine adrenocortical cells have been utilized to demonstrate that ACTH regulates the synthesis and thus the activity of NADPH-cytochrome P-450 reductase. The temporal pattern of induction correlates well with that previously reported for cytochromes P-45017α and P-450C21, microsomal steroid hydroxylases serviced by P-450 reductase. Results of in vitro translation studies suggest that ACTH regulates P-450 reductase synthesis at the transcriptional level and show that the adrenocortical enzyme is synthesized as the mature form. The action of ACTH to induce P-450 reductase synthesis in the adrenal cortex can be mimicked by dibutyryl cAMP, but not by phenobarbital which induces P-450 reductase synthesis in liver.
