(B) RT-qPCR analysis of VEGFR2 mRNA levels expressed in HUVECs after a 48-hour transfection (100 nM siRNA:siVEGFR2). All qPCR experiments were done in triplicate and VEGFR2 mRNA expression was normalized to the expression of GAPDH. (C) Western blot analysis of VEGFR2 protein and GAPDH protein expressed in HUVECs after a 72-hour transfection (100 nM siRNA:VEGFR2). Three independent experiments were performed. (D) Quantitative analysis of VEGFR2 protein expression levels. The expression of targeted protein was relative to the expression of GAPDH protein. *P0.05, **P0.01, compared with untreated; #P0.05, ##P0.01, compared with RPM; &&P0.01, compared with RPM/control siRNA;
