Abstract

The present invention provides new methods for detecting, diagnosing, monitoring, staging, prognosticating, imaging and treating colon cancer.

1 - 7 . (canceled)  
     
     
         8 . An antibody which specifically binds a polypeptide encoded by SEQ ID NO: 1.  
     
     
         9 . A method of imaging colon cancer in a patient comprising administering to the patient an antibody of  claim 8 .  
     
     
         10 . The method of  claim 9  wherein said antibody is labeled with paramagnetic ions or a radioisotope.  
     
     
         11 . A method of treating colon cancer in a patient comprising administering to the patient a molecule which downregulates expression or activity of CSG.  
     
     
         12 . A method of inducing an immune response against a target cell expressing CSG comprising delivering to a human patient an immunogenically stimulatory amount of a CSG protein so that an immune response is mounted against the target cell.
