Mucin1 (MUC1) is a transmembrane glycoprotein that is expressed on the apical surface of epithelial cells and is aberrantly overexpressed on most epithelial malignant tumors and some hematological malignant tumors, and it promotes the progression and tumorigenesis of many human adenocarcinomas [1-5]. Here, MUC1 is linked to adenocarcinoma.
