title: [Expressions of receptor tyrosine kinases mRNA and protein in carcinoma of bladder].
abstract: OBJECTIVE
  To detect the expressions of receptor tyrosine kinases (RTKs) mRNA and protein and to explore potentially promising tumor markers and conceivable drug target in bladder cancer.
  
  
  METHODS
  The expressions of RTKs mRNA and protein in tissue from invasive urothelial carcinoma of the bladder were examined by real-time quantitative PCR array and cytokine antibody array, with normal bladder tissue as control. The Results were analyzed using bioinformatic approaches.
  
  
  RESULTS
  The expressions of TGFA, STAB1, SERPINE1, ANGPT2, SPINK5, ANGPTL1, PROK1, MDK, CXCL9, GRN, RUNX1, VEGFA, and TGFB1 were obviously upregulated in bladder cancer tissue, while those of EDIL3, PTN, CCL2, PDGFD, FGF13, KITLG, FGF2, SERPINF1, and TNF were downregulated. ALK, Btk, EphB2, ErbB4, PDGFR-α, ROS, Tie-2, Tyk2, and VEGFR3 were over-expressed in bladder cancer, while FRK, Fyn, IGF-IR, Insulin R, Itk, JAK1, JAK3, and LCK were low-expressed.
  
  
  CONCLUSIONS
  Vascular endothelial growth factor/platelet-derived growth factor-targeted therapies may play an active role in treating carcinoma of bladder.
