Furthermore, in the liver, comparing HF-fed mice with HF + SFC-fed mice, iron supplementation significantly increased the expression of genes encoding components of beta-oxidation, such as carnitine palmitoyltransferase 1a (Cpt1a), hydroxyacyl-CoA dehydrogenase (Hadh), very long-chain acyl-CoA dehydrogenase (Vlcad), acyl-CoA synthetase long-chain family member 3 (Acsl3), enoyl-CoA hydratase short chain 1 (Echs1), malonyl-CoA decarboxylase (Mlycd), and long-chain acyl-CoA dehydrogenase (Lcad). The gene discussed is ECHS1; the disease is hydrops fetalis.
