As the most abundant and reversible RNA modification in eukaryotic cells, m6 A triggers a new layer of epi-transcription. M6 A modification occurs through a methylation process modified by "writers" complexes, reversed by "erasers", and exerts its role depending on various "readers". ⋯ Generally, the m6 A modification performs promotion or inhibition functions (dual role) in tumorigenesis and progression of various cancers, which suggests a new concept in cancer regulations. In addition, m6 A-targeted therapies including competitive antagonists of m6 A-associated proteins may provide a new tumour intervention in the future.
