FUT8 and breast carcinoma: Interestingly, higher expressions of the glycosyltransferases responsible for core fucosylation (FUT8), branching (GnT-V), and sialylation (both α-2, 3 and α-2, 6 sialytransferases) have been associated with a greater potential for motility, invasion and metastasis in breast cancer [39–42].
