EG-VEGF nucleic acids and polypeptides and method of use
View Patent ↗The present invention is directed to novel polypeptides designated herein as EG-VEGF 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. Also provided herein are methods of screening for modulators of EG-VEGF. Furthermore, methods and related methods of treatment are described herein which pertain to regulating cellular proliferation and chemotaxis.
1. An isolated antibody or antibody fragment thereof that specifically binds residues 20–105 of SEQ ID NO:2 and inbibits EG-VEGF induced proliferation of endothelial cells.
2. The antibody or antibody fragment thereof of claim 1 , wherein the antibody is a monoclonal antibody.
3. The antibody or antibody fragment thereof of claim 1 , wherein the antibody is a chimeric antibody.
4. The antibody or antibody fragment thereof of claim 1 , wherein the antibody is a humanized antibody.
5. The antibody or antibody fragment of claim 1 , wherein the antibody fragment is a Fab, Fab′, F(ab′) 2 , or Fv fragment.
6. The antibody or antibody fragment thereof of claim 2 , wherein the monoclonal antibody is produced by a hybridoma having ATCC accession number PTA-4119, PTA-4120, PTA-4121, or PTA-4122.
7. A composition comprising the antibody or antibody fragment thereof of claim 1 in admixture with a carrier.
8. The composition of claim 7 , wherein the carrier is a pharmaceutically acceptable carrier.
9. The composition of claim 7 , wherein the antibody is a monoclonal antibody.
10. The composition of claim 7 , wherein the antibody is a chimeric antibody.
11. The composition of claim 7 , wherein the antibody is a humanized antibody.
12. The composition of claim 7 , wherein the antibody fragment is a Fab, Fab′, F(ab′) 2 , or Fv fragment.
13. The composition of claim 9 , wherein the monoclonal antibody is produced by a hybridoma having ATCC accession number PTA-4119, PTA-4120, PTA-4121, or PTA-4122.
14. An article of manufacture, comprising:
(a) a container;
(b) a label on the container; and
(c) the composition of claim 8 .
15. The antibody or antibody fragment of claim 2 , wherein the antibody fragment is a fragment of a monoclonal antibody produced by a hybridoma having ATCC accession number PTA-4119, PTA4120, PTA-4121, or PTA-4122.
16. The composition of claim 9 , wherein the antibody fragment is a fragment of a monoclonal antibody produced by a hybridoma having ATCC accession number PTA-4119, PTA-4120, PTA-4121, or PTA-4122.
17. An isolated antibody or antibody fragment thereof that specifically binds a polypeptide comprising SEQ ID NO:2 and inhibits EG-VEGF induced endothelial cell proliferation.
