CUX1 and cancer: The methylation model revealed that the genes highly expressed in the high-risk group were SLC2A1, PTBP1, COL4A6, CUX1, and CA2; the genes highly expressed in the low-risk group were CHAF1A, DUOX1, STAC3, and IGBP1 (Figure 6(A)); The genes highly expressed in the cancer tissue were PTBP1, CA2, DUOX1, IQGAP3, CHAF1A, and STAC3; and genes with high expression in the normal adjacent tissue were CUX1, IGBP1, and COL4A6 (Figure 6(B)).
