Among these 12 aberrantly expressed m6A regulator genes, KIAA1429, HNRNPC, YTHDF1, RBM15, HNRNPA2B1, YTHDF2 were significantly up-regulated, while WTAP, METTL14, FTO, YTHDF3, YTHDC1, ALKBH5, and ZC3H13 exhibited decreased expression in BC tissues (Figure 2B). This evidence concerns the gene METTL14 and breast cancer.
