Research Abstract |
Hepatic iron overload in non-alcoholic fatty liver disease (NAFLD) patients with steatosis and insulin resistance has been frequently observed in clinical settings. In this study, I found the close association between the iron overload and aberrant lipid deposition in the liver. Since I have previously clarified that retinoids have a potent effect on the hepatic iron metabolism, the pathological effect of a retinoid in mice with NAFLD was investigated. Consequently, the retinoid was found to markedly improve the insulin resistance in the mouse model in a leptin-dependent manner.
