title: [Inhibition of proliferation of salivary adenoid cystic carcinoma by targeting gene transfer].
abstract: OBJECTIVE
  To investigate the expression of gene TRAIL driven by human telomerase reverse transcriptase (hTERT) promoter in SACC-83 cell tumor necrosis factor related apoptosis in dncing ligand.
  
  
  METHODS
  After pACTERT-TRAIL plasmid transfected was into SACC-83 and HEL cells through liposome, the expression of TRAIL was examined using RT-PCR technique, the cells' survival rate by methyl thiazolyl tetrazolium (MTT) method and apoptosis rate by flow cytometry.
  
  
  RESULTS
  Expression of extrinsic TRAIL gene driven by hTERT promoter was detected in SACC-83 cells, and not detected in human embryonic lung fibroblast (HEL) cells. After transfection of pACTERT-TRAIL, the proliferation of SACC-83 cells was significantly inhibited, and its apoptotic rate was promoted, whereas no inhibited effect was observed on HEL cells and its apoptotic rate showed little change.
  
  
  CONCLUSIONS
  hTERT promoter can be used to induce tumor-specific expression of TRAIL gene and apoptosis in SACC-83 cells.
