Therefore, we first analyzed the expression patterns of these proteins in the TCGA‐BLCA and Xiangya BLCA cohorts and found that S100A5, S100A7, S100A11, S100A14‐16, and S100B were significantly higher in carcinoma tissues than normal tissues in both cohorts (Figure S1A,B, Supporting Information). The gene discussed is S100B; the disease is bladder transitional cell carcinoma.
