Abstract
This study investigated the preventive effect of ribosomal protein S3 (rpS3) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ear edema in mice. A cell permeable expression vector PEP-1-rpS3 was constructed. Topical application of the vector markedly inhibited TPA-induced expression levels of cyclooxygenase-2 (COX-2) and pro-inflammatory cytokines. Application of PEP-1-rpS3 also resulted in a significant reduction in the activation of nuclear factor-kappa B (NF-. kB) and mitogen-activated protein kinase (MAPK) in TPA-treated ears. These results indicate that PEP-1-rpS3 inhibits inflammatory response cytokines and enzymes by blocking NF-. kB and MAPK, prompting the suggestion that PEP-1-rpS3 can be used as a therapeutic agent against skin inflammation.
