Research Abstract |
We now have investigating the function of histone deacetylase SIRT(sirtuin). To explore preventive effect against cell death, we have performed cell viability assay in PC12 and SHSY5Y cells with administration of hydrogen peroxide(H2O2) and 6-hydroxydopamine(6-OHDA). Administration of resveratrol, an activator of SIRT, and overexpression of SIRT1 resulted in significant inhibition of oxidative stress-induced cell death. We also found that overexpression of SIRT1H355Y, a dominant-negative SIRT1, showed partial inhibition of cell death. These results indicate that SIRT1 promotes cellular viability via deacetylase activity-dependent and -independent mechanisms.
