Abstract
Cytokine-induced apoptosis inhibitor 1 (CIAPIN1), known as anti-apoptotic and signal transduction protein, plays a pivotal role in a variety of biological progresses. However, the role of CIAPIN1 in inflammation is unclear. We investigated the protective effects of CIAPIN1 in lipopolysaccharide (LPS)-exposed Raw 264.7 cells and protection of CIAPIN1 against inflammatory damage induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) in mouse model using cell permeable Tat-CIAPIN1. Transduced Tat-CIAPIN1 significantly reduced ROS production and DNA fragmentation in LPS-exposed Raw 264.7 cells. Also, Tat-CIAPIN1 inhibited MAPKs and NF-リB activation as well as reduced the expression of Bax, cleaved caspase-3, COX-2, iNOS, IL-6 and TNF-メ in LPS-exposed the cells. In a TPA-induced animal model, transduced Tat-CIAPIN1 drastically decreased inflammation damage and inhibited COX-2, iNOS, IL-6, and TNF-メ expression. Therefore, these findings suggest Tat-CIAPIN1 might lead to a new strategy for the treatment of inflammatory skin disorders.
