METTL14 and neoplasm: The expression level of each m6A RNA methylation regulator between tumor and normal are presented as heatmaps (Figures 3A,B), showing that the expressions of most m6A RNA methylation regulators are significantly higher in tumor than normal group (Figure 3 and Figure S3), except for METTL14 and ZC3H13 (but the expression still trends higher among tumor group than normal).
