[ Method] 24 Guangxi Bama mini-pigs were fed with high-fat and high-sucrose diet, and partial sequences of exon 2 of PPARy-2 gene were amplified by using PCR method. In addition, the contents of fasting blood glucose and insulin （INS） in Guangxi Bama mini-pigs were determined, and the glucose tolerance test （GTT） was also carried out. [ Result] There was one SNP site （19813A/G） Jn partial sequence of exon 2 of the cloned PPAFly-2 gene, and AA （7 pigs） and AG （17 pigs） genotype were detected. The contents of fasting insulin and 60-min blood glucose in GTT in AG-genotype Guangxi Bama mini-pigs were significantly higher than those of AA genotype （ P 〈0.05）, while the incidence of T2DM in AG-genotype Guangxi Bama mini-pigs （71.4%） was obviously higher than that of AA gen- otype （5.9%）. [ Conclusion] The polymorphism of 19813A/G in exon 2 of PPARy-2 gene was related with the susceptibility of T2DM in Guangxi Bama mini-pigs.展开更多
