Ribavirin alone, IFN-α alone, or a combination of IFN-α and ribavirin inhibit migration of Renca or 786–0 cells. (A) The effect of IFN-α on migration of Renca cells (A) and 786–0 cells (B); The effect of ribavirin on migration of Renca cells (C) and 786–0 cells (D); (E) The effect of combined IFN-α and ribavirin treatment on migration of Renca and 786–0 cells (*indicates a significant difference in comparison with controls). (F, G) Representative images of crystal violet-stained control and treated Renca and 786–0 cells (combined treatment with IFN-α and ribavirin at different concentrations).
