The results of quantitative analyses confirmed that the expression levels of the fourteen m6A RNA methylation regulators in tumor tissues were significantly higher than the expression levels in normal tissues except ZC3H13 and METTL14 in TCGA cohort (Figure 1(c)), and the results in the ICGC cohort were consistent with TCGA cohort except METTL14 (Figure 1(d)). Here, ZC3H13 is linked to neoplasm.
