title: [Effects of hexamethylene bisacetamide on related genes expression of apoptosis and cell proliferating in human mucoepidermoid carcinoma cell line MEC-1].
abstract: OBJECTIVE
  To investigate the effects of hexamethylene bisacetamide (HMBA) on related genes expression of apoptosis and cell proliferating in human mucoepidermoid carcinoma cell line MEC-1.
  
  
  METHODS
  MEC-1 was induced 72 hours by 0.002 mol/L HMBA in vitro. The morphologic observation and the expression of PCNA, bcl-2, bax protein and bcl-2 mRNA were determined by microscope, immunohistochemistry, in situ hybridization and image analysis.
  
  
  RESULTS
  The expression of bax, bcl-2 protein and bcl-2 mRNA were higher than control group (P < 0.01). The related genes of cell proliferating PCNA were decreased in control group.
  
  
  CONCLUSIONS
  HMBA could inhibit the MEC-1 cell proliferation by down-regulation of PCNA expression, it could also induce apoptosis effectively that might be through the way of up-regulation of bax and bcl-2 gene expression.
