Additional file 3: Supplementary Figure 3. The genetic alterations of m6A regulators. (A) A total of 130 out of 399 (32.58%) COAD patients occurred genetic mutation. The number on the right demonstrated the mutation frequency of each m6A regulator. (B) The differential expression level of ALKBH5, METTL3, YTHDF1 and ZNF217 between ZC3H13 wild and mutation groups (P < 0.05).
