Prostaglandin Regulation of Adenylate Kinases Purified from Liver, Skeletal Muscle, and Hepatoma

Abstract

Adenylate kinases, purified from adult rat liver and skeletal muscle and from a fast growing hepatoma, were examined in the presence of a series of prostaglandins. Prostaglandins A1, A2, E1, E2 and F2alpha stimulated liver adenylate kinase 27% to 149%. All of these protaglandins stimulated the skeletal muscle enzyme from 47% to 82%. While prostaglandins A2 and E2 stimulated, prostaglandins A1 and F2alpha inhibited, and prostaglandin E1 was without effect on the hepatoma adenylate kinase.
