^aAnimals fed methionine choline-deficient (MCD) diet for 2 wk and pre-treated with the CAR agonist, TCPOBOP (3 mg/kg ip for 3 d at starting of diet). NS: Not significant; ER: Endoplasmic reticulum; L-PBE: L-peroxisomal bifunctional enzyme; ACO; Acetyl-CoA oxidase; Ketoacyl thiolase: Peroxisomal 3-ketoacyl-CoA thiolase; CPT1: Carnitine palmitoyltransferase; MTP: Mitochondrial trifunctional protein subunits alpha and beta.
