1 We found that hydrogen peroxide (H2O2) promotes PML deacetylation and identified SIRT1 and SIRT5 as PML deacetylases. Hydrogen Peroxide sirtuin 5 Homo sapiens
2 Both SIRT1 and SIRT5 are required for H2O2-mediated deacetylation of PML and accumulation of nuclear PML protein in HeLa cells. Hydrogen Peroxide sirtuin 5 Homo sapiens
3 Furthermore, ectopic expression of wild-type SIRT5 but not a catalytic defective mutant can also restore H2O2-induced cell death in SIRT1 knockdown cells. Hydrogen Peroxide sirtuin 5 Homo sapiens
