B3GAT2 and head and neck squamous cell carcinoma: The genes encoding sixteen glycotransferases responsible for N-glycosylation were obtained, and their transcript levels were analyzed in different HNSCC cell lines.11 Among these genes, FUT8, ST3GLA1, B3GAT1, B3GAT2, GCNT3, and MAGT3 were significantly upregulated in both HN6 and HN30 cells compared with normal epithelia (Fig. 5a).
