title: Antiangiogenic and antitumor effects of IMMUNEPOTENT CRP in murine melanoma.
abstract: BACKGROUND
  Skin cancers are common, and there has recently been a dramatic increase in their incidence, particularly in the occurrence of melanoma. Furthermore, relapse after curative surgical treatment of melanoma remains a significant clinical challenge and accounts for most of the mortality of this disease.
  
  
  OBJECTIVE
  The aim of this study was to determine whether IMMUNEPOTENT CRP affects B16F10 melanoma cells and tumors growth and vascular endothelial growth factor (VEGF) production in vivo and in vitro.
  
  
  METHODS
  B16F10 cells and B16F10-inoculated mice were treated with different concentrations of IMMUNEPOTENT CRP. Outcomes were then evaluated using MTT, TUNEL, Caspase-3, senescence, ELISA and colorimetric assays. Parameters related to survival and tumor weight were also assessed.
  
  
  RESULTS
  IMMUNEPOTENT CRP decreased the viability of B16F10 cells by increasing apoptosis of the treated cells, and VEGF production was decreased both in vitro and in vivo. Furthermore, treatment prevented metastasis, delayed the appearance of tumors, decreased tumor weight and improved the survival of tumor-bearing mice.
  
  
  CONCLUSIONS
  These observations suggest that IMMUNEPOTENT CRP can be used to suppress growth and metastasis by using targeting proteins such as VEGF.
