title: [Relative quantification of cytokeratin 19 transcription in oral squamous cell carcinoma tissues by fluorescent quantitive real-time RT-PCR].
abstract: OBJECTIVE
  To investigate the relative quantification of cytokeratin 19 transcription in oral squamous cell carcinoma tissues by fluorescent quantitive real-time reverse transcription-polymerase chain reaction ((RT-PCR).
  
  
  METHODS
  CK19mRNA level was detected by fluorescent quantitive real-time RT-PCR in cancerous and para-cancerous tissues from 31 oral squamous cell carcinoma patients. According to the 2(-DeltaDeltaCt) equation, the relative quantification fold of CK19mRNA level was calculated in cancerous tissues compared with para-cancerous tissues.
  
  
  RESULTS
  CK19mRNA levels in cancerous tissues were 2.21 folds higher than those in para-cancerous tissues, and the amplicon was specific. CK19mRNA level in cancerous tissue correlated significantly with pathological differentiation degree, the poorer the differentiation was, the higher the CK19mRNA level became.
  
  
  CONCLUSIONS
  Fluorescent quantitive real-time RT-PCR is accurate and reliable in the detection of relative quantification of CK19 transcription in oral squamous cell carcinoma tissues.
