Rat renal cortical and medullary slices incorporate [14C]arachidonate into phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and triacylglycerols. The percent distribution of [14C]arachidonate among the various phospholipids is similar in renal cortex and medulla, although the total amount of radioactively labeled phospholipids is higher in the renal medulla. Subsequent incubation of prelabeled slices in the presence of deoxycholate induces a loss of radioactivity from [14C]phosphatidylinositol, with a concomitant increase in 1,2-[14C]diacylglycerol. Neutral lipids are not affected. The degradation of phosphatidylinositol to [14C]diacylglycerol indicates the presence of phospholipase C activity. Renal medulla seems to be more sensitive to deoxycholate than the renal cortex. Deoxycholate also induces slightly the disappearance of some 14C radioactivity from phosphatidylethanolamine and phosphatidylcholine, which might reflect activation of phospholipase A2. The activity of the phospholipase C could constitute the first step in the sequence of reactions that leads to the release of arachidonic acid.
