摘要
雄性SD大鼠27只分为对照组、肥胖组、肥胖伴糖尿病组。测定血皮质酮浓度,行正葡萄糖高胰岛素钳夹实验。采用实时PCR检测各组大鼠肝X受体(LXR)、11β-羟基类固醇脱氢酶1(11β-HSD1)和糖皮质激素受体(GR)mRNA的表达情况。肥胖组和肥胖伴糖尿病组大鼠较对照组具有明显的胰岛素抵抗。与对照组相比,肥胖组和肥胖伴糖尿病组肝LXR mRNA表达均显著升高,11β—HSD1 mRNA表达均显著降低(均P〈0.05)。
Twenty-seven male SD rats were assigned to 3 groups : control, obese, and obese with diabetes groups. Serum corticosterone was determined and euglycemic-hyperinsulinemic clamp was carried out. Expressions of liver X receptor ( LXR), 11β-hydroxysteroid dehydrogenase 1 ( 11 β-HSD1 ), and glucocorticoid receptor (GR) were determined by real-time PCR. Both groups of obese rats were insulin-resistant, with up-regulated LXR mRNA and down-regulated 11β-HSD1 mRNA ( both P〈0. 05 ).
