Next, we examined the expression levels of p‐TFCP2L1 and CDK1 and their co‐expression in normal urothelium of the urinary bladder and in a tissue microarray (TMA) construct generated from transurethral resections of bladder tumor (TURBT) specimens from 400 patients at our institute (Kim et al, 2015b). The gene discussed is CDK1; the disease is urinary bladder neoplasm.
