RHESUS CARCINO EMBRYONIC ANTIGEN, NUCLEOTIDES ENCODING SAME, AND USES THEREOF

摘要

DNAs encoding rhesus monkey carcinoembryonic antigen (rhCEA) have been isolated, cloned and sequenced. The gene encoding CEA is commonly associated with the development of human carcinomas. The present invention provides compositions and methods to elicit or enhance immunity to the protein product expressed by the CEA tumor-associated antigen, wherein aberrant CEA expression is associated with a carcinoma or its development. This invention specifically provides adenoviral vector constructs carrying rhCEA and discloses their use in vaccines and pharmaceutical compositions for preventing and treating cancer.
