FTO and urinary bladder cancer: Previous studies have reported that FTO plays an oncogenic role in melanoma by reducing RNA degradation of critical melanoma‐promoting genes, including PD‐1 and CXCR4, via an m6A‐YTHDF2‐dependent mechanism55 and facilitates bladder cancer tumorigenesis and tumour cell viability through the FTO/MALAT/miR‐384/MAL2 signalling pathway.56
