Down regulation of VEGF expression using pshVEGF delivery into the cancer cells for 48 h by polymers. The VEGF expression were measured by human VEGF ELISA kit. (A) Quantification of down regulated VEGF expression shown by relative VEGF expression %. Relative VEGF expression (%) = Amount of VEGF (Treated)/Amonut of VEGF (Control) × 100. Cell growth inhibition of polymers with gWiz-Luc (B) or shVEGF (C) polyplexes were measured by MTT assay. Results are represented as mean ± SD. (n=3). *P<0.05, **P < 0.01, ***P <0.001 versus PEI 25 kDa.
