FTO and leukemia: Mechanically, R‐2HG binds to FTO and competitively suppresses its demethylase activity, thus resulting in the up‐regulation of global m6A modification, which in turn impairs the stability of MYC/CEBPA mRNAs and MYC/CEBPA involving signalling pathways in leukaemia cells sensitive to R‐2HG.63, 64
