B3GNT9 and glioblastoma: Corroborating previous findings that β3GNT8, another member of the same family as β3GNT9, demonstrates a significant increase of expression in glioblastoma, and can fuel the proliferation, invasion, and migration of glioblastoma cell (23), our research also suggests that β3GNT9 may influence the migration and invasion of glioblastoma, which in turn, causes the malignant biological behavior of glioblastoma.
