incubation of hepatocytes in the presence of phospholipase a2 ( 0.9 units/dish ) for 10 min prior to pulse-chase experiments resulted in an increase in radiolabel incorporation into phosphatidylcholine ( from 2.4 +/- 0.02.10 ( -5 ) dpm/dish to 3.1 +/- 0.1.10 ( -5 ) dpm/dish ) and a corresponding decrease in radiolabel associated with the choline ( from 2.5 +/- 0.05.10 ( -5 ) to 1.4 +/- 0.03.10 ( -5 ) dpm ) and phosphocholine fractions ( from 8.5 +/- 0.07.10 ( -5 ) to 6.9 +/- 0.05.10 ( -5 ) dpm ) .
