Dopamine inhibits corticosteroid secretion in frog adrenocortical cells: evidence for the involvement of prostaglandins in the mechanism of action of dopamine.

abstract：:We have recently demonstrated that the hypertensinogenic and natriuretic actions of ACTHI-39 can be found in a non-steroidogenic fragment of ACTH, ACTH4-10. These effects of ACTH or ACTH4-10 may be due to their ability to act as weak agonists of gamma MSH. gamma MSH is found in the 16K N-terminus of pro-opiocortin, an...
