title: [Effects of a novel gene NOR(1) on the protein expression of HepG2 cell line].
abstract: OBJECTIVE
  To investigate the mechanism of NOR(1) gene, a novel gene associated with liver cancer.
  
  
  METHODS
  NOR(1) was introduced into HepG2 cells by liposome transfection. After staining and image analysis, 6 differential expression spots which were up-regulated in NOR(1) transfected cells were isolated and identified by two-dimensional polyacrylamide gel eletrophoresis (2D PAGE) and MALDI-TOF.
  
  
  RESULTS
  The proteins which included zinc finger protein, tumor necrosis factor receptor, and protein tyrosine phosphatase receptor were involved in gene transcription and signal transduction associated with cancer.
  
  
  CONCLUSIONS
  NOR(1) gene may have some effects on liver cancer by up-regulating the expression of these proteins.
