As for the cellular expression, in comparison with that in a normal ureteral epithelial immortalized cell line, SV‐HUC‐1, CERCAM expression and protein levels were found to be significantly higher in five bladder carcinoma cell lines, T24, 5637, RT4, SW780, and J82 (Figure 1D,E); among the five bladder carcinoma cell lines, CERCAM expression and protein levels were higher in T24 and 5637 cells (Figure 1D,E). The gene discussed is CERCAM; the disease is urinary bladder carcinoma.
