title: [Cloning tumor-related genes and tumor suppressor genes in glioma with polymerase chain reaction-based subtractive hybridization].
abstract: OBJECTIVE
  Glioma is a common tumor in central nervous system with no specific clinical therapy. Its pathogenesis is unclear. This study was to clone tumor-related genes and tumor suppressor genes in glioma with polymerase chain reaction (PCR)-based subtractive hybridization, and to explore the molecular biological mechanism of tumorigenesis of glioma.
  
  
  METHODS
  mRNA was isolated from a sample of human glioma, and reversely transcribed into cDNA. PCR-based subtractive hybridization was used to clone tumor-related genes and tumor suppressor genes from it.
  
  
  RESULTS
  In tumor-related candidate gene group, phospho-protein enriched in astrocytes of 15 (PEA15) and homology of acid fibroblast growth factor (aFGF) were picked up. Whereas, in tumor suppressor gene group, interferon-induced protein 17 and ndr2 were picked up. ndr2 was widely expressed in normal brain tissue, but absent in glioma tissue.
  
  
  CONCLUSIONS
  ndr2 gene is a candidate tumor suppressor gene, and may play a role in tumorigenesis of glioma.
