DIURNAL VARIATION IN THE ACTIVITY OF HEPATIC GLYCEROL-3-PHOSPHATE ACYLTRANSFERASE IN RESPONSE TO OVINE PROLACTIN IN GOLDFISH, CARASSIUS AURATUS L.

Abstract
Prolactin has a time-dependent effect on lipid metabolism in several species of teleost fishes. Whether the diurnal effects of prolactin on lipid levels may be mediated in part by enzyme activity regulation was studied. There is a diurnal variation in the stimulation of hepatic glycerol-3-phosphate acyltransferase activity when prolactin is administered to goldfish.
