ABSTRACT
<p><b>OBJECTIVE</b>To assess suppression effects of vector-based small interfering RNA (siRNA) on vascular endothelial growth factor (VEGF) expression of human tongue squamous carcinoma cell line (Tca8113) in vitro.</p><p><b>METHODS</b>Two siRNA targeting VEGF constructed in eukaryotic expression vector (Pu-VEGF-siRNA1, Pu-VEGF-siRNA2), eukaryotic expression vector as the experiment control, all of which were transfected into Tca8113 cells with Lipofectamine 2000. Non-transfection cell was used as negative control. VEGF mRNA and protein were detected by reverse transcription polymerase chain reaction (RT-PCR), immunohistochemistry and enzyme linked immunosorbent assay (ELISA), respectively.</p><p><b>RESULTS</b>Compared to the experimental and negative controls, the expression of VEGF mRNA and protein were significantly decreased in the Pu-VEGF-siRNA1 group and Pu-VEGF-siRNA2 group. But there were no significant differences between two controls (P > 0.05).</p><p><b>CONCLUSION</b>Vector-based siRNAs targeting VEGF are efficient in down-regulating VEGF expression in Tca8113 cells.</p>
