Hepatitis C virus E2 protein involve in insulin resistance through an impairment of Akt/PKB and GSK3ß signaling in hepatocytes. Hsieh MJ, Lan KP, Liu HY, Zhang XZ, Lin YF, Chen TY, Chiou HL. BMC Gastroenterol. 2012 Jun 21;12(1):74. [Epub ahead of print]
BACKGROUND: Hepatitis C virus (HCV) infection may cause liver diseases of various severities ranging from primary acute infection to life-threatening diseases, such as cirrhosis or hepatocellular carcinoma with poor prognosis. According to clinical findings, HCV infection may also lead to some extra-hepatic symptoms, including type 2 diabetes mellitus (DM). Since insulin resistance is the major etiology for type 2 DM and numerous evidences showed that HCV infection associated with insulin resistance, the involvement of E2 in the pathogenesis of type 2 DM and underlying mechanisms were investigated in this study. RESULTS: Results showed that E2 influenced on protein levels of insulin receptor substrate-1 (IRS-1) and impaired insulin-induced Ser308 phosphorylation of Akt/PKB and Ser9 phosphorylation of GSK3beta in Huh7 cells, leading to an inhibition of glucose uptake and glycogen synthesis, respectively, and eventually insulin resistance. CONCLUSIONS: Therefore, HCV E2 protein indeed involved in the pathogenesis of type 2 DM by inducing insulin resistance.
