Title Interferons specifically suppress the translation from the internal ribosome entry site of hepatitis C virus through a double-stranded RNA-activated protein kinase-independent pathway.
Journal J Infect Dis
Abstract Interferon (IFN) therapy is used worldwide as the best available treatment for hepatitis C virus (HCV) infection; however, little is known about how IFN or other drugs work against liver diseases. The effect of 6 drugs (glycyrrhizin, ursodeoxycholic acid, ribavirin, methylprednisolone, IFN-alpha, and IFN-beta) on HCV RNA translation from the HCV internal ribosome entry site (IRES) was investigated, using a bicistronic reporter containing the HCV IRES. IFNs suppressed both cap-dependent and HCV IRES-dependent translation, with HCV IRES-dependent translation being more significantly suppressed. In contrast to HCV IRES, IFN did not suppress either foot-and-mouth disease virus IRES-dependent or encephalomyocarditis virus IRES-dependent translation more than it suppressed cap-dependent translation. Moreover, dominant inhibition of HCV IRES-dependent over cap-dependent translation depended neither on the double-stranded RNA-activated protein kinase activation nor on La protein function. These results indicate a novel antiviral effect of IFNs against HCV.
