The effect of vasopressin on the short-term regulation of fatty acid synthesis was studied in isolated hepatocytes from rats fed ad libitum. Vasopressin stimulates fatty acid synthesis by 30-110%. This increase is comparable with that obtained with insulin. Angiotensin also stimulates fatty acid synthesis, whereas phenylephrine does not. The dose-response curve for vasopressin-stimulated lipogenesis is similar to the dose-response curve for glycogenolysis and release of lactate plus pyruvate. Vasopression also stimulates acetyl-CoA carboxylase activity in a dose-dependent manner. Vasopressin does not relieve glucagon-inhibited lipogenesis, whereas insulin does. The action of vasopressin on hepatic lipogenesis is decreased, but not suppressed, in Ca2+-depleted hepatocytes. The results suggest that vasopressin acts on lipogenesis by increasing availability of lipogenic substrate (lactate + pyruvate) and by activating acetyl-CoA carboxylase.
