Abstract

In a screen for sterol regulatory element-binding protein (SREBP)-1c target genes in the liver, we identified long chain fatty acyl-CoA synthetase 5 (ACS-5). Hepatic ACS-5 mRNA is poorly expressed during fasting and diabetes and strongly induced by carbohydrate refeeding and insulin treatment. In cultured hepatocytes, insulin and a high glucose concentration induce ACS-5 mRNA. Adenoviral overexpression of a nuclear form of SREBP-1c in liver of diabetic mice or in cultured hepatocytes mimics the effect of insulin to induce ACS-5. By contrast, a dominant negative form of SREBP-1c abolishes the effect of insulin on ACS-5 expression. The dietary and SREBP-1c-mediated insulin regulation of ACS-5 expression indicate that ACS-5 is involved in the anabolic fate of fatty acids.
