As shown, nine overlapping differential expressed genes, including B4GALNT2, B4GALT4, DPM1, FUT3, ST3GAL2, ST3GAL4, ST6GAL1, ST6GALNAC1, and ST6GALNAC2 (Figure 2A) were then transferred to random forest (RF) method to identify genes mostly relevant to CRC patient prognosis in GEO and TCGA cohorts. Here, FUT3 is linked to colorectal carcinoma.
