To date, it has been reported that some oncogenes play crucial role in the progression of bladder cancer, such as fibroblast growth factor receptor 3 (FGFR3) [4, 5], DEP domain–containing 1 (DEPDC1) [6], M-phase phosphoprotein 1 (MPHOSPH1) [7], and P73 [8]. Here, KIF20B is linked to urinary bladder cancer.
