Abstract
The mechanism of hormone-stimulated prostaglandin E2 biosynthesis was investigated in rabbit renomedullary interstitial cells in tissue culture. Angiotensin II, bradykinin, and arginine vasopressin stimulated arachidonic acid release and subsequent prostaglandin biosynthesis. Indomethacin completely inhibited prostaglandin biosynthesis without affecting arachidonic acid release. Mepacrine, a phospholipase inhibitor, inhibited arachidonic acid release without affecting subsequent synthesis of prostaglandin E2. Our studies suggest that arachidonic acid release via hormone-activated phospholipase or acylhydrolase (or both) is the mechanism of hormone-stimulated prostaglandin E2 biosynthesis.Entities:
