Common polymorphisms in the PPARgamma2 and IRS-1 genes and their interaction influence serum adiponectin concentration in young Finnish men

The Gly972Arg substitution of the insulin receptor substrate-1 (IRS-1) gene and the Pro12Pro genotype of the peroxisome proliferator-activated receptor gamma 2 (PPARgamma2) gene have been suggested to be associated with type 2 diabetes mellitus. In this study, the influence of these two polymorphism...

Description
Summary:The Gly972Arg substitution of the insulin receptor substrate-1 (IRS-1) gene and the Pro12Pro genotype of the peroxisome proliferator-activated receptor gamma 2 (PPARgamma2) gene have been suggested to be associated with type 2 diabetes mellitus. In this study, the influence of these two polymorphisms on serum adiponectin concentrations was investigated. The Pro12Ala polymorphism of the PPARgamma2 gene and the Gly972Arg polymorphism of the IRS-1 gene were genotyped in 252 young Finnish servicemen. The Ala12Ala genotype of PPARgamma2 was associated with a higher adiponectin level compared to the Pro12Ala genotype (p=0.02) and the Pro12Pro genotype (p=0.02). Total (p=0.02) and low-density lipoprotein (LDL) cholesterol (p=0.03) levels were higher in subjects with the Pro12Pro genotype compared to the Pro12Ala genotype. No difference was observed in serum adiponectin level between the IRS-1 genotype groups. The subjects with X972Arg of this gene had high total and LDL cholesterol levels (p
