Abstract:
The present invention is directed to novel methods for inhibiting angiogenesis and treating tumors and cancer by targeting tropomyosin (Tpm) expressed on the surface of endothelial cells and/or tumor cells, to Tpm polypeptides and peptides, as well as variants and derivatives thereof that bind inhibitors of angiogenesis, and to anti-Tpm antibodies that block or stimulate angiogenesis. Cyclic peptides that bind to the D5 subunit of HKand inhibit angiogenesis are also included. Method for screening test compounds as candidate antiangiogenic molecule that binds to Tpm are disclosed, as are affinity ligands comprising the proteins, peptides, variants and derivatives of the invention.
