The m6A erasers, accounting for the demethylation of m6A in RNAs, include fat mass and obesity-associated (FTO) andα-ketoglutarate-dependent dioxygenase AlkB homolog 5 (ALKBH5) (Jia et al., 2011; Zheng et al., 2013). This evidence concerns the gene FTO and obesity due to melanocortin 4 receptor deficiency.
