MUC1 is a tumor-related glycoprotein decorated with the TF antigen, and it has been proposed that the aberrant interaction between MUC1 presenting TF disaccharide epitopes, and hGal-3 promotes cancer progression (Glinsky et al., 2001; Goletz et al., 2002; Takenaka et al., 2002). This evidence concerns the gene MUC1 and cancer.
