FBP1 and FBP3 expression in normal urothelium and cancer of the urinary bladder. Papillary bladder cancer with weak (A), with moderate (B), and with strong (C) expression of FBP1 (all 20×). D) Illustration of the heat sensitivity of the FBP1 epitope, which is not detectable in coagulated areas (centrally), whereas the signal is well retained at the periphery (arrow). Papillary bladder cancer with weak (E, 20×), moderate (F, 40×; G, 20×)), and with a strong (H, 40×) expression of FBP3, respectively.
