STAT1-CC plus IFN-γ transfected resistant (GR17-1) cells display a marked reduction in HCV NS3 protein.

<p>IFN-γ resistant cells were transfected separately with the respective STAT1 plasmid and treated with or without IFN-γ. At 72 hours the cells were mounted onto a glass slide, stained for with DAB for HCV NS3 (brown), and counterstained with hematoxylin (blue). Huh7 cells without virus were used as a negative control.
