The glycan array established that hRTL preferentially recognized type-3 (Galβ1-3GalNAc) and type-1 galactosides, such as the TF-antigen and lacto N-biose, inducing cytotoxicity in gastric cancer cells, such as DLD-1, which expresses the mucin-associated TF-antigen [25]. The gene discussed is MUC5AC; the disease is gastric cancer.
