Alteration of the lipase activities of muscle, adipose tissue and liver by rapeseed oil feeding of rats.

Abstract

Feeding rapeseed oil, rich in erucic acid, for 4 days results in a significant increase of the lipoprotein lipase activities of heart and adipose tissue. The lipase activity of liver, which in earlier studies has been shown to be releasable by heparin perfusion, also increases by the dietary regimen. The increased lipoprotein lipase activity of heart may contribute to lipid accumulation in this organ. The higher intracellular lipid store probably results in higher (hormone-sensitive) tissue lipase activity. The increase of lipoprotein lipase of adipose tissue, however, is not accompanied by an increase of hormone-stimulated tissue lipase activity in fat cells. This activity may even become lower, and might contribute to the decrease of the lipid store in heart after an initial rapid phase of fat accumulation during erucic acid feeding.
