摘要
The effect of activation of liver X receptor by N-(2,2,2-trifluoroethyl)-N-[4-[2,2,2-trifluoro-1-hydroxy-1(trifluoromethyl)ethyl]phenyl] benzenesulfonamide (T0901317) on high fat diet (HFD)-induced obesity and insulin resistance was examined in C57BL/6 mice. When on HFD continuously for 10 weeks, C57BL/6 mice became obese with an average body weight of 42 g, insulin resistant, and glucose intolerant. Twice weekly intraperitoneal injections of T0901317 at 50 mg/kg in animals on the same diet completely blocked obesity development, obesity-associated insulin resistance, and glucose intolerance. Quantitative real-time PCR analysis showed that T0901317-treated animals had significantly higher mRNA levels of genes involved in energy metabolism, including Ucp-1, Pgc1a, Pgc1b, Cpt1a, Cpt1b, Acadm, Acadl, Aox, and Ehhadh. Transcription activation of Cyp7a1, Srebp-1c, Fas, Scd-1, and Acc-1 genes was also seen in T0901317-treated animals. T0901317 treatment induced reversible aggregation of lipids in the liver. These results suggest that liver X receptor could be a potential target for prevention of obesity and obesity-associated insulin resistance.
