MALAT1 and urinary bladder cancer: Overall, in bladder cancer cells, knockdown of FTO significantly (p < 0.001) decreased the relative expression level (Figure 3G) and half‐life (Figure 3H) of MALAT1 mRNA, whereas FTO overexpression significantly increased, by 2.2‐fold, the relative expression level and half‐life of MALAT1 mRNA (Figure 3I).
