| Outline of Final Research Achievements |
In this study, for the detailed and reliable analyses about the interaction of HCV with host factors, we established gene knockout (KO) Huh7 cells. By using zinc finger nuclease (ZFN), TALEN and CRISPR/Cas9 system, several gene KO Huh7 cells were established. In the analyses about HCV assembly using ApoB, ApoE or MTTP KO cells, we clarified that apolipoproteins participate in the formation of infectious HCV particles. In the analyses about autophagy and HCV infection suggest that HCV-RNA replication inhibits de novo autophagy through the induction of LC3 lipidation around the replication complex. In addition, we revealed that miR-122 expression strongly enhances not replication but translation of viral RNA through the direct interaction with 5'UTR of HCV-RNA.
The results in this study will provide clues to the life cycle of HCV and assist in the development of novel antivirals targeting the assembly process of HCV.
