The effects of clofibrate feeding on the metabolism of polyunsaturated fatty acids were studied in isolated rat hepatocytes. Administration of clofibrate stimulated the oxidation and particularly the peroxisomal beta-oxidation of all the fatty acids used. The increase in oxidation products was markedly higher when n-3 fatty acids were used as substrate, indicating that peroxisomes contribute more to the oxidation of n-3 than n-6 fatty acids. The whole increase in oxidation could be accounted for by a corresponding decrease in acylation in triacylglycerol while the esterification in phospholipids remained unchanged. A marked stimulation of the amounts of newly synthesized C16 and C18 fatty acids recovered, was observed when 18:2(n-6), 20:3(n-6), 18:3 (n-3) and 20:5(n-3), but not when 20:4(n-6) and 22:4(n-6) were used as substrate. This agrees with the view that extra-mitochondrial acetyl-CoA produced from peroxisomal beta-oxidation is more easily used for fatty acid new synthesis than acetyl-CoA from mitochondrial beta-oxidation. The delta 6 and delta 5 desaturase activities were distinctly higher in cells from clofibrate fed rats indicating a stimulating effect.
