Abstract

Adiponectin is an adipocyte-secreted protein that modulates insulin sensitivity and whose low circulating concentration is associated with insulin resistance. In the present study, we analysed the association between two single-nucleoticle polymorphisms (SNPs) in the adiponectin gene and insulin resistance in 253 nondiabetic subjects. In addition, we investigated whether this association is modulated by body mass index (BMI) levels. The SNPs + 45T>G and +276G>T in the human adiponectin gene were detected in real-time PCR with LightCycler. No association was found with the + 45T>G SNP. The +276G> T SNP was associated with higher BMI (PIR (P2. In both subgroups, subjects carrying the +276G>T SNP had higher HOMAIR; however, the difference was highly significant among leaner (P2, the relative risk of insulin resistance was 9.7 (CI: 1.32-87.7, P T SNP had significantly (P<0.05) lower mean serum adiponectin levels (25.7 ng/ml) compared to noncarriers (37.0 ng/ml), suggesting a possible influence of the +276G>T SNP on adiponectin levels. In summary, we observed an association between the +276G>T SNP in the adiponectin gene and insulin resistance. In particular, among leaner individuals, the adiponectin gene appears to determine an increased risk to develop insulin resistance.
