  • Title: Short-term effects of triiodothyronine on exogenous and de novo synthesized fatty acids in rat hepatocytes.
    Author: Muci MR, Gnoni GV.
    Journal: Biochem Int; 1991 Dec; 25(5):807-13. PubMed ID: 1804101.
    Abstract:
    The short-term effect of T3 both on de novo synthesized and on exogenously added fatty acids was studied in isolated rat hepatocytes. Lipogenesis from [14C] acetate or [3H] H2O was stimulated by the addition of T3. In contrast, the utilization of exogenous [14C] palmitate for the synthesis of longer chain fatty acids was markedly reduced. This T3-induced inhibition was removed by octanoylcarnitine, an inhibitor of carnitine palmitoyl-transferase I and of fatty acid oxidation. T3 also stimulated glycerolipid synthesis from acetate, neutral lipids being more influenced than phospholipids, but reduced the incorporation of palmitate in all the lipid fractions. It is suggested that T3 exerts opposing effects on the hepatic utilization of newly synthesized and exogenous fatty acids.
