An increasing number of studies have confirmed that m6A writers (METTL3, METTL14, KIAA1429, WTAP), erasers (FTO and ALKBH5) and readers (YTHDC1, YTHDC2, YTHDF1, YTHDF2 and HNRNPC) have distinct functions within different types of cancer cells [46, 47]. This evidence concerns the gene YTHDC2 and cancer.
