Additionally, MGAT-5, a glycosyltransferase responsible for β1-6 branching of proteins, including β1-integrin, and associated with poor patient outcome, tumorigenesis and metastasis in BC [27], [35], [36], was upregulated (7.4 fold) in SK-β1-C1 cells (data not shown). Here, MGAT5 is linked to breast cancer.
