Abstract: Cancer associated antigens have been identified by autologous antibody screening of libraries of nucleic acids expressed in small cell lung cancer cells using antisera from cancer patients. The invention relates to nucleic acids and encoded polypeptides which are cancer associated antigens expressed in patients afflicted with small cell lung cancer. The invention provides, among other things, isolated nucleic acid molecules, expression vectors containing those molecules and host cells transfected with those molecules. The invention also provides isolated proteins and peptides, antibodies to those proteins and peptides and cytotoxic T lymphocytes which recognize the proteins and peptides. Fragments of the foregoing including functional fragments and variants also are provided. Kits containing the foregoing molecules additionally are provided.

Abstract: The invention relates to antibodies which bind to the cancer associated antigen NY-ESO-1.

Abstract: The invention provides for the production of several humanized murine antibodies specific for the antigen Lewis Y, which is recognized by the murine antibody Lewis Y. The Lewis Y antigen is expressed in normal tissues but the level of expression is higher in certain tumor types so that the antigen can be used as a marker for cells of some breast, colon, gastric, esophageal, pancreatic, duodenal, lung, bladder and renal carcinomas and gastric and islet cell neuroendocrine tumors. The invention also provides for numerous polynucleotide encoding humanized Lewis Y specific antibodies, expression vectors for producing humanized Lewis Y specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized Lewis Y specific antibodies. Additionally, the invention provides methods of treating cancer using humanized Lewis Y specific antibodies.
