title: [Expression of transforming growth factor-betal (TGF-beta1) and its role in human laryngeal and hypopharyngeal carcinoma].
abstract: OBJECTIVE
  To detect the mRNA expression of transforming growth factor-betal (TGF-beta1) in laryngeal and hypopharyngeal carcinoma, and to explore the pathogenesis of the two types neoplasms.
  
  
  METHODS
  We examined the expression of TGF-beta1 mRNA in the tissue of human laryngeal and hypopharyngeal carcinoma from patients. The TGF-beta1 mRNA expression was determined by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).
  
  
  RESULTS
  The TGF-beta1 mRNA expression was significantly stronger in 17 cases of 20 laryngeal and hypopharyngeal carcinoma.
  
  
  CONCLUSIONS
  The result suggested that the expression level of TGF-beta1 in laryngeal and hypopharyngeal carcinoma may inhibit the human immunity and enhance the growth and metastasis of the laryngeal and hypopharyngeal carcinoma.
