According to the recent studies, there were 13 m6A regulator genes confirmed to affect cancer progression, including the “writer” (KIAA1429, METTL3, METTL14, RBM15, WTAP, and ZC3H13), the “readers” (HNRNPC, YTHDC1, YTHDC2, YTHDF1, and YTHDF2), and the “erasers” (ALKBH5 and FTO) (Zhang et al., 2020c; Zhang et al., 2020b). Here, HNRNPC is linked to cancer.
