Objective: To explore the relationship between multivariate factors and type 2 diabetes mellitus.
Methods: Polymorphisms of microsatellite markers in uncoupling protein 3 (UCP3) gene, hormone-sensitive lipase (HSL) gene and protein tyrosine phosphatase-1B (PTP-1B) gene were tested in 106 patients with type 2 diabetes and 102 control subjects by performing polymerase chain reaction (PCR), polyacrylamide gel electrophoresis and silver staining. Multivariate logistic regression analysis was performed by all factors.
Results: Through univariate analysis, type 2 diabetes had significantly positive associations with age, systolic blood pressure (SBP), fasting insulin (FINS) level, cholesterol, triglyceride, low-density lipoprotein, apolipoprotein B (ApoB), alpha lipoprotein, UCP3 gene allele 6, UCP3 gene allele 7, HSL gene allele 9, and negative associations with UCP3 gene allele 1 and 3, HSL gene allele 5, high-density lipoprotein. The results of multivariate logistic analysis showed that UCP3 gene allele 6, UCP3 gene allele 7, SBP, ApoB, alpha lipoprotein were still positively related to type 2 diabetes, while HSL gene allele 5, high-density lipoprotein were still negatively related to type 2 diabetes.
Conclusion: Our data showed that UCP3 gene allele 6, UCP3 gene allele 7, SBP, abnormity of plasma ApoB and alpha lipoprotein might play a role in the development of type 2 diabetes. HSL gene allele 5, high-density lipoprotein might play some protective role in the development of type 2 diabetes.
