title: [Suppression of vascular endothelial growth factor expression by vector-based small interfering RNA in human tongue squamous carcinoma cell line Tca8113].
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Vector-based siRNAs targeting VEGF are efficient in down-regulating VEGF expression in Tca8113 cells.
