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. The gene discussed is PIGV; the disease is glioma.
