Clinical specimens for immunohistochemical analysis were collected from a cohort of 124 bladder cancer patients to clarify the expression pattern of the candidate hub genes (CORO1C, TMPRSS4, PIK3C2B, and ZNF692) identified in the above modules, and the main findings were shown in Figures 5E–L. This evidence concerns the gene PIK3C2B and urinary bladder carcinoma.
