Popis: SIRT1 is a stress sensor whose deacetylase activity is increased during cellular stress, but the molecular mechanism is unclear. Here, the authors show that O-GlcNAcylation of SIRT1 is elevated upon different stress stimuli and increases SIRT1 deacetylase activity, protecting cells from stress-induced apoptosis.
