IRIS è il sistema di gestione integrata dei dati della ricerca (persone, pubblicazioni, progetti, attività) adottato dall’Università di Palermo, e ha lo scopo di raccogliere, conservare, documentare, e diffondere ad accesso aperto le informazioni relative alla produzione scientifica degli autori afferenti all’Ateneo.
EnglishToday it is clearly evident that genetic background constitutes an integral part of aging and longevity. Many studies on long-lived people have been conducted emphasizing the role of certain genes in long life. Classic case-control studies, genome-wide association studies, and high-throughput sequencing have permitted identification of a variety of genetic variants seemingly associated with longevity. Over the years, aging research has focused on the insulin/insulin-like growth factor-1 (IGF-1) signaling pathway because of its evolutionarily conserved correlation with life-span extension in model animals. Indeed, many single-nucleotide polymorphisms (SNPs) associated with longevity were identified in genes encoding proteins that take part in this metabolic pathway. Closely related to this pathway is the Klotho gene. It encodes a type-I membrane protein expressed in two forms, membrane and secreted. The latter form suppresses oxidative stress and growth factor signaling and regulates ion channels and transporters. In particular, its over-expression seems to be able to suppress insulin/IGF-1 signaling extending life span. Thus, our aim was to assemble the results in the literature concerning the association between the functional variant of the Klotho "KL-VS" stretch, which contains six polymorphisms in linkage disequilibrium, and successful aging to quantify the possible effect of the variants. The results of our systematic review indicate that the Klotho KL-VS variant is associated with healthy aging.
