title: [Expression and significance of NGX6 gene in human hepatocellular carcinoma].
abstract: OBJECTIVE
  To examine the expression of NGX6 gene and to investigate its association with the clinico-pathological characteristics in hepatocellular carcinoma(HCC).
  
  
  METHODS
  Samples from 45 patients were divided into the hepatocellular carcinoma tissue group and the matched paracancerous tissue group. Reverse transcription polymerase chain reaction(RT-PCR) was used to detect the expression of NGX6 gene in the hepatocellular carcinoma and the surrounding normal tissue specimens.
  
  
  RESULTS
  The positive rates of NGX6 in the hepatocellular carcinoma and the matched paracancerous tissues were 35.5%(16/45)and 77.8%(35/45), and the ratios of NGX6/G3PDH mRNA were 0.245+/-0.060 and 0.352+/-0.113.There was significant difference in the 2 groups (P<0.05). The expression of NGX6 gene was related to TNM staging (chi2=6.106,P=0.042)and lymph node metastasis(chi2=5.237,P=0.022)in hepatocellular carcinoma.
  
  
  CONCLUSIONS
  There is positive expression of NGX6 in the hepatocellular carcinoma and the matched paracancerous tissues. The low-expression or non-expression of NGX6 gene plays an important role in the gene transcription level in hepatocellular carcinoma.The expression of NGX6 gene is related with TNM staging and lymph node metastasis in hepatocellular carcinoma. Expression of NGX6 might be used as an early indicator of the occurrence and development of hepatocellular carcinoma.
