Alterations in core fucosylation, outer-arm fucosylation, sialylation and glycan branching have been found in the serum of patients with liver disease.17 Similarly, there are also many groups that give greater insight into the underlying biological mechanisms of aberrant glycosylation in lung cancer.18,19 For example, the role of α-1,3-fucosyltransferase (Fut3) in the synthesis of sLex and prognosis of its physiological function have been assessed in lung cancer. This evidence concerns the gene FUT3 and lung carcinoma.
