As for other GT genes belonging to our model, B3GNT8 was associated with malignancy and metastasis of glioma [27], while FUT11 [28], FUT4 [29], GALNT16 [30], GALNT8 [31], MGAT4C [32], and PIGV [33] have been individually studied in various type of tumors previously and are correlated with tumor malignancy, proliferation, cancer stem cells, and immune cell attraction. Here, POFUT4 is linked to central nervous system cancer.
