Abstract

BACKGROUND: We investigated the effects of the common polymorphisms in the peroxisome proliferator- activated receptor gamma2 (PPAR-gamma2 Pro12Ala) and in PPAR-gamma coactivator 1alpha (PGC-1alpha Gly482Ser) genes on the association with the nephropathy of Korean patients with type 2 diabetes mellitus.
METHODS
A total of 113 patients with type 2 diabetes and 123 patients with diabetic nephropathy were enrolled in this study. The Pro12Ala polymorphism of the PPAR-gamma2 gene and the Gly482Ser polymorphism in the PGC-1alpha gene were determined with the polymerase chain reaction amplification, BstU-I and Msp I enzyme digestion, and gel electrophoresis.
RESULTS
The genotype and allelic frequency of PPAR-gamma2 Pro12Ala gene were not different statistically between the diabetic nephropathy and the control. The genotype of PGC-1alpha Gly482Ser in diabetic nephropathy was also not different from those in control. The allelic frequency and carriage rate of Ser allele in PGC-1alpha Gly482Ser were significantly higher in patients with diabetic nephropathy than those in control (respectively, p<0.05).
CONCLUSION
The polymorphisms of the PGC-1alpha Gly482Ser gene are significantly associated with the nephropathy in Korean patients with type 2 diabetes mellitus.
