Abstract:
Compositions comprising or encoding one or more peptides that inhibit the Bcr—Abl oncoprotein and that bind to molecules involved in Bcr—Abl function are disclosed. The peptides and polypeptides inhibit the growth of, and induce cell death of, Philadelphia chromosome-positive leukemia cells expressing the Bcr—Abl oncoprotein. Methods for treating leukemias (e.g., CML, ALL and AML), including autologous bone marrow transplant therapy, using the peptide and polypeptide compositions of the invention are also provided.
