The mechanisms which control the cell cycle and growth of adrenocortical cells remain largely uncharacterized. ACTH binds to its G protein-coupled receptor (GPCR), the melanocortin 2 receptor (MC2R) in the adrenal cortex and mediates the production of cAMP resulting in steroidogenesis. ACTH however also remains a candidate for the control of growth in the adrenal cortex. It is well known to have a growth promoting effect in vivo but has an opposing effect in some cell systems ...
