| Research Abstract |
Endothxin (LPS) causes hepatocytic apoptosis and liver dysfunction, as described in cases of sepsis. In this study, we therefore investigated the functions of a new WD-repeat domain containing protein naofen (WDR35) in LPS-induced liver dysfunction. LPS activated Kuppfer cells and released cytokines, such as TNF-alpha. Which then increased mRNA and protein expression of naofen in hepatocytes. Naofen/WDR35 inhibited expressions of anti-apoptotic proteins Bcl-2 and Bcl-xL, and stimulated apoptosis of hepatocytes. These results suggested that naofen may be involved in endotoxin-induced liver injury, and as a new therapeutic targets for endotoxin-induced liver injury therapy.
