The combination treatment of sorafenib (Sor) and PGV-1 in JHH-7 and Huh-7 cells inhibited the proliferation irreversibly. (a) The percentage of cell upon combination in JHH-7 and Huh-7 cells. The results in the graph were expressed as mean ± SD (n = 3). Means denoted by a different letter indicate significant differences between treatments (p < 0.05). (b) The combination index (CI) of Sor and PGV-1 in JHH-7 and Huh-7 cells. (c) The representative qualitative colony formation assay in JHH-7 (upper) or Huh-7 (lower) cells after staining with crystal violet.
