SIRT1 targets over 100 different proteins involved in metabolism, stress responses, and longevity pathways, including the tumor suppressor p53, the transcriptional coactivator PGC-1, and the DNA repair protein Ku70. Through deacetylation of PGC-1, SIRT1 promotes mitochondrial biogenesis and oxidative metabolism, while deacetylation of p53 reduces apoptotic responses to mild stress, promoting cellular survival and longevity
