in neonatal rat islet cells prelabelled with [ 14c-methyl ] choline , the phorbol ester 12-o-tetradecanoylphorbol-13-acetate rapidly activated a phospholipase d-like mechanism as suggested by the accumulation in cells and medium of choline ( but not of phosphorylcholine or glycerophosphorylcholine , markers for phospholipase c and phospholipase a2 action on phosphatidylcholine ) .
