title: [Expression of RAGE in laryngeal squamous cell carcinoma and clinical significance].
abstract: OBJECTIVE
  To study the expression and clinical significance of receptor for advanced glycation end products (RAGE) in laryngeal squamous cell carcinoma (LSCC).
  
  
  METHODS
  immunohistochemical staining was used to detect the expressions of RAGE protein and semiquantitative method of reverse transcriptase polymerase chain reaction (RT-PCR) was used to analyze the expression level of RAGE mRNA in LSCC tissues and laryngeal normal tissues of 37 cases, respectively.
  
  
  RESULTS
  The mRNA and protein expression of RAGE was significantly higher in LSCC than that in normal laryngeal tissues (P < 0.05), correlated with differentiation (P < 0.01), but not with tumor stage and location (P > 0.05).
  
  
  CONCLUSIONS
  The expression levels of RAGE were significantly higher in LSCC than these in laryngeal normal tissues, RAGE is involved in differentiation of LSCC.
