    • The carbohydrate antigen disialyl Lewis a, which is at least partly synthesized by ST6GALNAC6, is a normal counterpart of sialyl Lewis a, better known as CA19-9, an antigen widely used as a serum marker for diagnosis of cancers in the digestive track. Disialyl Lewis a is predominantly expressed in non-malignant epithelial cells of the digestive organs, while sialyl Lewis a is preferentially expressed in cancers. Disialyl Lewis a in normal epithelial cells serves as a ligand for immunosuppressive receptors, such as SIGLEC7 and SIGLEC9, expressed on resident monocytes/macrophages and maintains immunological homeostasis of mucosal membranes in digestive organs. Sialyl Lewis a, as well as its positional isomer sialyl Lewis x, serves as a ligand for vascular cell adhesion molecule E-selectin and facilitates hematogenous metastasis through mediating adhesion of circulating cancer cells to vascular endothelium (PubMed:17760270).
