m6A can be dynamically removed by “erasers” such as FTO (FTO alpha-ketoglutarate-dependent dioxygenase) or ALKBH5 (AlkB homolog 5, RNA demethylase) in response to environmental stimuli including memory formation, cancer development and stress responses (Wang et al., 2020; Vaasjo 2022). This evidence concerns the gene FTO and cancer.
