Effect of vitamin A supplementation on adipose tissue 11β-HSD1 activity in WNIN/Ob lean and obese rats. Values are means ± S.E for 8 rats. Mean values with * mark are significant at P ≤0.05 level (by one-way ANOVA). Comparisons were made between normal and high vitamin A-fed groups of each phenotype (AI-Lean: 2.6 mg vitamin A/kg diet, AII-Lean: 129 mg vitamin A/kg diet, BI-Obese: 2.6 mg vitamin A/kg diet and BII-Obese: 129 mg/kg diet).
