Proteomics of HCV Replication Complex

Project Details

Description

DESCRIPTION (provided by applicant): Chronic infection by hepatitis C virus (HCV) is the leading cause of severe hepatitis, which often develops into liver cirrhosis and hepatocellular carcinoma. The molecular mechanisms underlying HCV replication and pathogenesis are poorly understood. The identity of host or viral proteins relevant to the state of liver disease associated with HCV infection is not known. Although we have recently identified various cellular factors that interact with HCV 3'NTR (Appendix #1), nothing is known about the components of the HCV replication complex. These components are expected to have crucial roles in the production of infectious HCV virions. We have devised a means of capturing the replication complex in situ from HCV-infected cells and identifying its components by proteomics technology. We will investigate the implication of each identified cellular component on HCV replication by siRNA-mediated genetic knockdown of its expression in the cells. This will yield valuable information about the identity of the cellular or viral factors associated with the replication complex and facilitate the identity of new targets for use in preventing the viral infection.
