We combined TCGA and GTEx databases to further compare the expression of FTO in different cancers, and found that FTO was expressed in 25 tumors, including in ACC, BRCA, CHOL, COAD, READ, DLBC, ESCA, GBM, HNSC, KICH, KIRC, KIRP, LAML, LGG, LIHC, LUAD, LUSC, MESO, OV, PAAD, PCPG, PRAD, READ, SKCM, STAD, STES, TGCT, THCA, UCEC, and showed a low expression in CESC (Figure 6A). This evidence concerns the gene FTO and cancer.
