Antibodies to polypeptides encoded by a nucleic acid underexpressed in esophageal tumor
View Patent ↗The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
1. A method for the diagnosis of esophageal tumor comprising:
(a) identifying a patient suspected of having esophageal tumor; and
(b) detecting expression of a polypeptide having the amino acid sequence of SEQ ID NO: 136 in a test sample from said patient,
wherein lower expression of said polypeptide in said test sample as compared to a normal control sample indicates the presence of esophageal tumor.
2. The method of claim 1 , wherein the test sample and control sample are esophageal tissue.
3. The method of claim 1 , wherein said test sample is selected from the group consisting of cultured cell line, primary tumor, tissue, cells, and blood.
4. The method of claim 1 , wherein expression of said detecting of expression of said polypeptide in said test sample is detected using an antibody that specifically binds to the polypeptide of SEQ ID NO: 136.
5. The method of claim 4 , wherein said antibody is detectably labled.
6. The method of claim 4 , wherein said antibody is a monoclonal antibody.
7. The method of claim 4 , wherein said antibody is a humanized antibody.
8. The method of claim 4 , wherein said antibody is an antibody fragment.
9. The method of claim 8 , wherein the antibody fragment is selected from the group consisting of Fv, Fab Fab′, and F(ab′)2 fragments.
