Considering the regulatory role of YAP1/TEAD4 in KIF4A transcription in esophageal squamous cell carcinoma and the role of TEAD1 in chemoresistance of bladder cancer,9, 15 we sought to investigate whether YAP1/TEAD1 is involved in KIF4A dysregulation in UBC. This evidence concerns the gene YAP1 and urinary bladder cancer.
