dc.description.abstract | Sirtuin 2 (SIRT2), a member of the sirtuin family of proteins, plays an important role in cell survival. However, the biological function of SIRT2 protein is unclear with respect to inflammation and oxidative stress. In this study, we examined the protective effects of SIRT2 on inflammation and oxidative stress-induced cell damage using a cell permeative PEP-1-SIRT2 protein. Purified PEP-1-SIRT2 was transduced into RAW 264.7 cells in a time- and dose-dependent manner and protected against lipopolysaccharide- and hydrogen peroxide (H2O2)-induced cell death and cytotoxicity. Also, transduced PEP-1-SIRT2 significantly inhibited the expression of cytokines as well as the activation of NF-kappa B and mitogen-activated protein kinases (MAPKs). In addition, PEP-1-SIRT2 decreased cellular levels of reactive oxygen species (ROS) and of cleaved caspase-3, whereas it elevated the expression of antioxidant enzymes such as MnSOD, catalase, and glutathione peroxidase. Furthermore, topical application of PEP-1-SIRT2 to 12-O-tetradecanoylphorbol 13-acetate-treated mouse ears markedly inhibited expression levels of COX-2 and proinflammatory cytokines as well as the activation of NE-kappa B and MAPKs. These results demonstrate that PEP-1-SIRT2 inhibits inflammation and oxidative stress by reducing the levels of expression of cytokines and ROS, suggesting that PEP-1-SIRT2 may be a potential therapeutic agent for various disorders related to ROS, including skin inflammation.
