(A) Effect of vitamin A supplementation on hepatic LXRα mRNA and protein levels in WNIN/Ob lean and obese rats. Quantified densitometric values are expressed relative of 1 for AI (lean) as control. (B) Representative photo of LXRα PCR product, stained by ethidium bromoide. (C) Representative photo of β-Actin PCR product (internal control), stained by ethidium bromide. (D) Quantified densitometric values from the western blot are expressed relative of 1 for lean control rats (AI). (E) Representative Western blot of hepatic LXRα protein. (F) Ponseau stained western blot. Values are means ± SE for 3-4 rats at P ≤0.05 level. Comparisons were made between normal and high vitamin A-fed groups of each phenotype (A I-Lean: 2.6 mg vitamin A/kg diet, A II-Lean: 129 mg vitamin A/kg diet, B I-Obese: 2.6 mg vitamin A/kg diet and B II-Obese: 129 mg/g diet).
