Figure 2. Comparison of the expression of m6A regulators in breast cancer and normal controls. (A) There were showed expression of m6A regulators in normal and tumor sample by heatmap (Red, high expression; Blue, low expression). (B) Vio-plot showed the significant differential expression of 20 m6A regulator genes in normal and tumor sample. The asterisks represented the statistical p value (*P < 0.05; **P < 0.01; ***P < 0.001).
