title: [Effect of pSUPER/CD147siRNA on the growth of malignant melanoma in nude mice].
abstract: OBJECTIVE
  To investigate the effect of pSUPER/CD147siRNA on the formation, proliferation, and angiogenesis of malignant melanoma in nude mice.
  
  
  METHODS
  The nude mouse subcutaneous xenotransplantation models of malignant melanoma were constructed and observed using morphological analysis. The protein expression of PCNA and CD31 in tumors was detected using immunohistochemical technique. Tumoral proliferative activity in the nude mice was quantitatively evaluated by proliferation cell nuclear antigen (PCNA). Microvessel density( MVD) was counted based on the endothelial cells positively stained with anti-CD31 antibody.
  
  
  RESULTS
  The subcutaneous tumors appeared in all the nude mice 5 days later after the transplantation, but the volume of malignant melanoma in the experiment group significantly decreased compared with the control group (P<0.01). PCNA expression and MVD were significantly lower in the experiment group than those in the control group ( P<0.01).
  
  
  CONCLUSIONS
  CD147 siRNA inhibits the growth and angiogenesis of malignant melanoma in vivo, suggesting that CD147 might be a new gene therapy target molecule for malignant melanoma.
