title: [Differential expressions of the receptor for advanced glycation end products in prostate cancer and normal prostate].
abstract: OBJECTIVE
  To study the differential expressions of the receptor for advanced glycation end products (RAGE) in the tissues of prostate cancer and normal prostate, and to find the role of RAGE in the pathogenesis of prostate cancer.
  
  
  METHODS
  We collected the tissue of prostate cancer and that of normal prostate from the same patient, and compared the differential expressions of RAGE at the tissue, protein and mRNA levels between prostate cancer and normal prostate tissues of 10 patients by immunohistochemistry, Western blot and real-time quantitative PCR.
  
  
  RESULTS
  Immunohistochemistry exhibited a significantly higher expression of RAGE in the prostate cancer tissue than in the normal prostate tissue; Western blot showed that the RAGE protein expression was 2.13 times higher in the former than in the latter (P < 0.05); and real-time quantitative PCR revealed the RAGE mRNA expression of the former to be 4.2 times that of the latter (P < 0.05).
  
  
  CONCLUSIONS
  RAGE may play an important role in the pathogenesis and progression of prostate cancer.
