Breast, gastric and prostate cancer associated antigens and uses therefor
First Claim
1. A method of diagnosing prostate cancer comprising:
- contacting a biological sample isolated from a subject with an antibody or antigen binding fragment thereof that specifically binds with an expression product of a nucleic acid molecule, which is (a) a nucleic acid molecule that encodes a polypeptide having at least 99% sequence identity to the amino acid sequence of SEQ ID NO;
1218, (b) a nucleic acid molecule that differs from SEQ ID NO;
504 in codon sequence due to degeneracy of the genetic code, or (c) a full length complement of (a) or (b), anddetermining the interaction between the antibody or antigen binding fragment thereof and the expression product, wherein a determination that the antibody or antigen binding fragment thereof interacts with the expression product indicates that the expression product is present in the sample and that the patient has prostate cancer.

Abstract
Cancer associated antigens have been identified by autologous antibody screening of libraries of nucleic acids expressed in breast, gastric and prostate 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 cancer. The invention provides, inter alia, 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. The molecules provided by the invention can be used in the diagnosis, monitoring, research, or treatment of conditions characterized by the expression of one or more cancer associated antigens.
