title: [Analysis of characteristics of gene expression in pericancerous stromal cells of nasopharyngeal carcinoma by cDNA array].
abstract: OBJECTIVE
  The mechanism of how stromal cell play an important role in nasopharyngeal carcinogenesis is now a hotspot. This study was designed to elucidate the possible mechanism of stromal cell in the occurrence and progression of nasopharyngeal carcinoma (NPC) through the analysis of the characteristics of gene expression in pericancerous stromal cells of NPC by cDNA array.
  
  
  METHODS
  The atlas human select tumor arrays were used to compare the expression profiles between NPC tissue and NPC cell lines.
  
  
  RESULTS
  Pericancerous stromal cells in NPC expressed at least 40 genes specifically.
  
  
  CONCLUSIONS
  The specific expression of these genes in pericancerous stromal cells provides energy materials for growth of NPC cells; furthermore, it can accelerate the degradation of extracellular matrix, thus promoting the metastasis of NPC cells.
