Uridine, a pyrimidine nucleoside, can modulate liver lipid metabolism although its specific acting targets have not been identified. Using mice with fenofibrate-induced fatty liver as a model system, the effects of uridine on liver lipid metabolism are examined. At a daily dosage of 400 mg-kg, fenofibrate treatment causes reduction of liver NAD+-NADH ratio, induces hyper-acetylation of peroxisomal bifunctional enzyme ECHD and acyl-CoA oxidase 1 ACOX1, and induces excessive accumulation of long chain fatty acids LCFA and very long chain fatty acids VLCFA. Uridine co-administration at a daily dosage of 400 mg-kg raises NAD+-NADH ratio, inhibits fenofibrate-induced hyper-acetylation of ECHD, ACOX1, and reduces accumulation of LCFA and VLCFA. Our data indicates a therapeutic potential for uridine co-administration to prevent fenofibrate-induced fatty liver.
