TGR5多种配体抑制高脂饮食小鼠肥胖及高血糖的效果对比研究
Comparison of the Effects of TGR5 Ligands on Obesity and Hyperglycemia in High Fat Diet Mice
摘要
Abstract
Objective To screen out the best ligand by comparing the weight loss and hypoglycemic effects of various ligands for bile acid receptor TGR5 in diet-induced obese mice. Methods Wild-type mice of 6 weeks old were fed with HF or the control regular chow diet for 10 weeks. Then mice fed with HF were randomly divided into seven groups. One group were kept feeding with HF. The other groups were switched to HF+OA(H)、HF+OA(L)、HF+CDCA、HF+CA、HF+DCA、HA+LCA for additional 10 weeks. Glucose tolerance test and serum insulin levels were detected after 20 weeks. Hematoxylin and eosin staining was performed for standard histological examination in liver and adipose tissues. Expression of genes related to glucose metabolism in adipose tissues was measured by Real-time PCR. Mice body weights were monitored during the entire process. Results TGR5 activation by its ligands decreased the body weight, enhanced insulin sensitivity in mice and up-regulated the expression of genes related to fatty acid synthesis and oxidation in adipose tissues, with OA(H), CDCA and CA affected significantly. Conclusion OA(H)、CDCA and CA were identified as being effective at reducing weight, improving glucose tolerance, reducing serum insulin levels, relieving liver lipid deposition and regulating the expression of fat metabolism related genes.关键词
