Additional file 2: Supplementary Figure 2. The expression level, CNV changes and mutations of m6A regulators in COAD. (A) The difference of mRNA expression level of m6A regulators between COAD tumor and non-tumor tissues in TCGA cohort. The results showed that 23 out of 27 regulators were dysregulated in COAD. (B) The location on different chromosomes and CNV changes of m6A regulators. The outer layer represented the chromosomes and the inner layer was the location of m6A regulators. Red dots represented more CNV gain and blue dots represented more loss frequency. (C) The gain and loss of CNV frequency of m6A regulators were represented by red and green dots, respectively.
