title: [Alterations of transforming growth factor beta 1 and p27kip1 mRNAs in gastric mucosa carcinogenesis].
abstract: OBJECTIVE
  To investigate the effect of transforming growth factor beta 1 (TGF beta 1) and p27kip1 in gastric mucosa carcinogenesis.
  
  
  METHODS
  RT-PCR was used to detect TGF beta 1 and p27kip1 mRNAs in normal gastric mucosa, simple hyperplasia, dysplasia and gastric carcinoma tissues respectively.
  
  
  RESULTS
  There were expressions of TGF beta 1 and p27kip1 mRNAs in normal gastric mucosa, simple hyperplasia, dysplasia and gastric carcinoma tissues, the expressive levels of TGF beta 1 and p27kip1 mRNAs decreased gradually among the four groups. The expressive level of TGF beta 1 and p27kip1 mRNAs in gastric carcinoma group were significantly lower than those in other three groups(P < 0.05).
  
  
  CONCLUSIONS
  The data indicate that TGF beta 1 and p27kip1 may play an important role in the development and carcinogenesis of gastric carcinoma. Semi-quantification PCR technique is effective for detecting mRNA expressive level in tissues.
