title: [The expression of nuclear factor kappa B in cancer cells of human adenocarcinoma].
abstract: OBJECTIVE
  Nuclear factor kappa B is very important in cis-activation which regulates the expression of many genes. This study inquired into the mechanism of cancer cell metastasis.
  
  
  METHODS
  Immunohistochemical method was used for studying the expression of nuclear factor kappa B in cancer cells of human metastasized rectum adenocarcinoma.
  
  
  RESULTS
  Expressed nuclear factor kappa Bp65 was found in the cancer cells of peritumoral tissues and metastasized lymph nodes. The reaction product was located in the cytoplasm and cytonucleus.
  
  
  CONCLUSIONS
  The findings of this study suggest a strong correlation between the expression of nuclear factor kappa B in cancer cells and the metastasis of cancer.
