We analyzed differences in gene expression between cancer and paracancer in each cancer sample obtained from the TCGA database (Figure 1(c)) in READ (P < 0.05), BLCA, COAD (P < 0.01), BRCA, CHOL, LIHC, LUAD, LUSC, PRAD, STAD (P < 0.001), THCA, and UCEC (P < 0.001), while AP1M2 expression levels in GBM, LGG (P < 0.05), KICH, KIRC, and KIRP (P < 0.001) were elevated compared with those in the normal control group (control tissues). Here, AP1M2 is linked to cancer.
