Abstract: The invention relates to the isolation of a nucleic acid molecule which encodes a cancer associated antigen. Also a part of the invention is the antigen itself, and the uses of the nucleic acid molecule and the antigen, and peptides derived from it.

Abstract: The invention relates to antibodies which bind to the cancer associated antigen NY-ESO-1. Both polyclonal and monoclonal antibodies are part of the invention, as are chimeric forms of the antibodies, and binding portions of antibodies. Uses of these antibodies are described. Also described are truncated, recombinant forms of the cancer associated antigen.

Abstract: The invention relates to methods for determining tumor status by determining antibodies specific to NY-ESO-1 in patient samples. One can determine whether a cancerous condition is progressing, regressing, or remaining stable by determining antibodies against NY-ESO-1 in a patient sample, and comparing the value obtained to a prior value. When the tumor in question expresses NY-ESO-1, a change in this value is indicative of a change in status of the cancerous condition.

Abstract: Various molecules associated with disorders such as colon cancer are disclosed. The invention also discloses diagnostic and therapeutic methods based upon these molecules.

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.

Abstract: The invention relates to monoclonal antibodies which specifically bind to the tumor rejection antigen precursor molecule MAGE-1, hybridomas which produce these monoclonal antibodies, and their use. Also described is a recombinant form of MAGE-1, peptides which are useful as immunogens, and immunogenic compositions containing the peptides and an adjuvant.

Abstract: The invention relates to monoclonal antibodies which specifically bind to the tumor rejection antigen precursor molecule Melan-A, hybridomas which produce these monoclonal antibodies, and their use. Also described is a recombinant form of Melan-A and immunogenic compositions containing the molecules, and an adjuvant.

Abstract: An antigen which is specific to vascular endothelium is described. Described is a cell surface antigen which consists of four subunits; of 190, 145, 125 and 110 kd as determined by SDS-PAGE under reducing conditions as is a monoclonal antibody specific to this antigen. Uses, both diagnostic and therapeutic, are also described.
