Figure 9. Effects of recombinant N-SLIT2 protein on vascular endothelial growth factor mRNA levels in human retinal pigment epithelium cells. Vascular endothelial growth factor (VEGF) mRNA expression in human retinal pigment epithelium (RPE) cells was significantly increased with increasing concentrations of recombinant N-SLIT2 protein as measured by real-time RT–PCR 24 h after recombinant N-SLIT2 administration. Values are reported as the mean±SD from three independent experiments. Asterisks denote values significantly different between the treatment group and control group (p<0.05). The relative expression level of the control group cell was set to 1.
