Effects of different treatments on VEGF and KSP mRNA expression in Hep3B cells. The mRNA relative level of VEGF (A) and KSP (B) with different treatments in Hep3B cells by Real-time qRT-PCR. The mRNA expressions of VEGF and KSP were normalized with β-actin. Values were given as mean value ± standard deviation (SD) of triplicate. **p < 0.01, *p < 0.05 compared to untreated cell group and #p < 0.05 compared to siRNA cocktail treated cell group.
