Abstract

Mitochondrial glycerophosphate-acetyltransferase activity (GPAT) was determined in the isolated and perfused liver of diet-induced hyperlipemic rats, and was found to be significantly increased compared to normal rats, A positive correlation existed between hepatic triglyceride output and GPAT. Perfusion of 10(-5) M glucagon induced a significant reduction in GPAT levels. It is suggested that the lipid-lowering action of glucagon may be mediated also through an inhibition of GPAT activity.
