Parathyroid hormone increased the incorporation of Na2H32PO4 into phosphatidic acid and phosphatidylinositol in cat renal cortical slices. Incorporation was not observed into any other phospholipid. The effects were seen as early as one minute for phosphatidic acid and ten minutes for phosphatidylinositol. 8-Bromoadnosine 3',5'-monophosphate did not mimic the effects of parathyroid hormone. Concentrations of parathyroid hormone, 1 x 10(-8)M to 1 x 10(-7)M, which increased the incorporation of 32p into phosphatidic acid and phosphatidylinositol maximally, did not alter tissue cyclic AMP levels suggesting that the incorporation of 32p was independent of cyclic AMP.
