The result showed that the expression of METTL3 (T = 4.8, N = 5.4) and FTO (T = 4.9, N = 5.3) was significantly lower, whereas that of METTL14 (T = 4.2, N = 3.8) was higher in breast cancer tissues than that in normal tissues, but the difference in the expression of WTAP (T = 5.9, N = 6.2) and ALKBH5 (T = 5.7, N = 5.5) was not very significant (Figure 1A). This evidence concerns the gene METTL3 and breast cancer.
