title: Transfection and expression of HCV-NS5B gene in Huh-7 cells.
abstract: OBJECTIVE
  To study the mechanism of hepatitis C virus (HCV) replication and to test gene therapy for hepatitis C, a human liver cell line expressed HCV RNA polymerase has been established.
  
  
  METHODS
  NS5B gene has been transfected into Huh-7 cells by lipofectamine. The results of transfection were confirmed by PCR and Southern blot analysis, and the level of the non-structural protein 5B (NS5B) in Huh-7 cells was detected by Western blot analysis.
  
  
  RESULTS
  There were NS5B gene fragments and the expression of NS5B protein in Huh-7c cells transfected with pTeT-NS5B or pcDNA-NS5B plasmid.
  
  
  CONCLUSIONS
  We have established a HCV RNA polymerase expression system in Huh-7 cells which can be further used to analyze the mechanism of HCV replication and provide a cell model for gene therapy in vitro.
