Research Abstract

Resistin causes insulin resistance, a feature of type 2 diabetes. We analyzed genetic and environmental factors affecting resistin gene expression. In～2000 subjects in the Japanese general population, plasma resistin was low with G at single nucleotide polymorphism(SNP)-420 and G at SNP-358, but highest with G at SNP-420 and A at SNP-358. This combination of these SNPs also showed the highest promoter activity. Therefore, A at SNP-358 is required for G at SNP-420 to confer the highest plasma resistin.
