Abstract:
Objective To investigate the relationship of peroxisome proliferator activated receptor gamma ( PPAR?)C161T gene polymorphism with related diseases of metabolic syndrome. To disscuss the mechanism of the elderly diseases from gene level and the relation between the gene polymorphism and lipid metabolism. Methods Three hundred seventy one non-sibship subjects of Han nationality were investigated in this study, including 69 old healthy subjects, 302 elderly cases diagnosed as metabolic syndrome. PPAR? C161T gene polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism, and radioimmunoassay was used to detect serum insulin. The insulin resistance was obtained from homeostasis model assessment (HOMA), and blood glucose, blood lipoprotein, height, weight and so on were tested. The frequencies of PPAR? C161T genotypes and the allele were compared with the clinical data. Results (1) In the groups of old normal health and metabolic syndrome, "T" allele frequency was 0.217,0.201, and "C" allele frequency was 0.783, 0.798 . There was no significant difference between the groups. (2)The triglyceride in CC genotypes of the metabolic syndrome was significantly higher than that in "T" allele carriers. Conclusions (1) The distributing trend of PPAR ? C161T gene polymorphism of the Han nationality in Wuhan in the elderly normal healthy group was in accord with that in the group of the elderly metabolic syndrome. (2) PPAR ? C161T substitution can influence metabolic syndrome, especially in liporprotain metabolism. "T" allele is associated with lower level of triglyceride.
