Abstract

Recent studies have demonstrated a significant association between mutations in genes involved in the insulin/IGF1 signaling pathway and extension of the life span of model organisms. In this study which compared 122 Japanese semisupercentenarians (older than 105) with 122 healthy younger controls, we examined polymorphic variations of six genes which are involved in insulin/IGF1 signaling. These genes were FOXO1A, INSR, IRS1, PIK3CB, PIK3CG, and PPARGC1A. We investigated the possible association of each gene locus and longevity by haplotype-based association analyses using 18 SNPs from public databases and the published literature. One INSR haplotype, which was comprised of 2 SNPs in linkage disequilibrium, was more frequent in semisupercentenarians than in younger controls.
