The increased level of GlcNAc bisection, which is consistent with elevations in expression of MGAT3 in PTC specimens as shown here, suggest that future studies with PTC samples should further assess its association with cancer progression status, as other studies have reported that increased bisection of N-glycans is associated with progression, metastasis, and poor survival in other cancers [58,59,60]. Here, MGAT3 is linked to cancer.
