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. The gene discussed is ZNF692; the disease is urinary bladder cancer.
