Knockdown of CP-PVX mRNA by target specific siRNA in cultured mammalian cells 24 h post transfection. (A) CP-PVX mRNA knockdown caused by siRNA1 in HepG2 cells. (B) CP-PVX mRNA knockdown caused by siRNA2 in HepG2 cells and (C) CP-PVX mRNA knockdown caused by siRNA3 in HepG2 cells. One-Way ANOVA and post Dunnet’s test were applied. The results showed that there was significant difference among control and different concentrations in standard value. (P < 0.05; n = 3).
