1 This release is largely independent of PLC activation and is mediated by a PLA2 because: 1) phosphatidylcholine is the preferential source of [3H]arachidonate release; 2) [3H]arachidonic acid release and phosphatidylcholine hydrolysis are blocked by two inhibitors of solubilized PLA2, mepacrine, and 4-p-bromophenacylbromide; and 3) we evidenced a PLA2 activity in cell homogenates.
