Outline of Final Research Achievements |
We have focused on interferon stimulated genes (ISGs), which were involved in efficacy of interferon (IFN)-based therapy for chronic hepatitis C, and investigated regulatory effects of ISG on viral replication in hepatitis C virus (HCV). (1) We have produced newly established cell lines, HCV subgenomic replicon (Huh7/Rep-Feo), which were in-vitro models simulating cellular autonomous replication of HCV genomic RNA. (2) We showed that GBP-1, IFI-6-16, and IFI-27 had directly inhibited subgenomic replication and virus production of HCV. (3) Investigation of molecular interaction of the ISGs with HCV proteins showed that GBP-1 bound HCV-NS5B directly. A protein truncation assay showed that the guanine binding domain of GBP-1 and the finger domain of NS5B were involved in the interaction.
