Title: Hsps and aging.

Authors: Tower, John

Published In Trends Endocrinol Metab, (2009 Jul)

Abstract: Heat-shock proteins (Hsps) are increasingly being implicated in aging phenotypes and control of life span across species. They are targets of the conserved heat-shock factor and insulin/IGF1-like signaling pathways that affect life span and aging phenotypes. Hsps are expressed in tissue-specific and disease-specific patterns during aging, and their level of expression and induction by stress correlates with and, in some instances, predicts life span. In model organisms, Hsps have been shown to increase life span and ameliorate aging-associated proteotoxicity. Finally, Hsps have emerged as key components in regulating aging-related cellular phenotypes, including cell senescence, apoptosis and cancer. The Hsps, therefore, provide a metric of individual stress and aging and are potential targets for interventions in aging and aging-related diseases.
