The identification and cloning of several tumour antigens together with an improvement in the understanding of the mechanisms involved in antigen presentation and immune recognition has opened up the possibility of using active specific immunotherapy as a treatment for certain cancers. This review discusses the tumour-associated MUC1 gene product of the polymorphic epithelial mucin (PEM), as a potential target molecule for cancer treatment. PEM is both over-expressed and aberrantly glycosylated in many carcinomas resulting in an antigenically distinct molecule. Furthermore, immune responses specific for PEM have been detected in cancer patients. Both syngeneic and transgenic murine model systems have been developed in order to compare the efficacy and toxicity of various PEM-based immunogens in tumour rejection studies, and to further improve the understanding of antigen presentation and the mechanisms underlying tumour rejection. Such models also allow the examination of MUC1-based immunogens as a treatment for existing tumours. Clinical trials in progress using immunogens based on the MUC1 gene product are briefly discussed.

Sequence Data, Molecular,Molecular Sequencing Data,Data, Molecular Sequence,Data, Molecular Sequencing,Sequencing Data, Molecular
D002240	Carbohydrate Sequence	The sequence of carbohydrates within POLYSACCHARIDES; GLYCOPROTEINS; and GLYCOLIPIDS.	Carbohydrate Sequences,Sequence, Carbohydrate,Sequences, Carbohydrate
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D000951	Antigens, Neoplasm	Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumor cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin.	Neoplasm Antigens,Tumor Antigen,Tumor Antigens,Antigen, Tumor,Antigens, Tumor
D014614	Vaccines, Synthetic	Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.

D016233	Immunotherapy, Active	Active immunization where vaccine is administered for therapeutic or preventive purposes. This can include administration of immunopotentiating agents such as BCG vaccine and Corynebacterium parvum as well as biological response modifiers such as interferons, interleukins, and colony-stimulating factors in order to directly stimulate the immune system.

D018396	Mucin-1	Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
