FAT4 and neoplasm: We found that FAT4 expression in tumor tissues of BLCA, BRCA, COAD, KICH, KIRP, LIHC, LUAD, LUSC, PRAD, READ, THCA, UCEC (P < 0.001), CESC(P < 0.01), and GBM (P < 0.05) was lower than that in the control tissues corresponding to the TCGA dataset, but we did not find significant differences in other tumors, such as ACC, DLBC, and ESCA (Figure 1).
