Abstract: ROR2 is provided as a therapeutic target and prognostic marker for cancers, which include without limitation specific carcinomas and sarcomas. This invention also provides for the use of conjugates comprising an antibody that recognizes and binds ROR2, and a cytotoxic agent. In the cytotoxic conjugates, the cell binding agent has a high affinity for ROR2 and the cytotoxic agent has a high degree of cytotoxicity for cells expressing ROR2, such that the cytotoxic conjugates of the present invention form effective killing agents. In a preferred embodiment, the cell binding agent is an anti-ROR2 antibody or an epitope-binding fragment thereof, more preferably a humanized anti-ROR2 antibody or an epitope-binding fragment thereof, wherein a cytotoxic agent is covalently attached, directly or via a cleavable or non-cleavable linker, to the antibody or epitope-binding fragment thereof.

Abstract: The invention provides a variety of reagents for use in the diagnosis and management of breast cancer. The invention utilizes cDNA microarray technology to identify genes whose expression profile across a large group of tumor samples correlates with that of cytokeratin 5 and cytokeratin 17, markers for basal cells of the normal mammary lactation gland. The invention demonstrates that tumors that express cytokeratin 5/6 and/or 17 have a poor prognosis relative to tumors overall. The invention provides basal marker genes and their expression products and uses of these genes for diagnosis of breast cancer and for identification of therapies for breast cancer. In particular, the invention provides basal marker genes including cadherin3, matrix metalloproteinase 14, and cadherin EGF LAG seven-pass G-type receptor 2. The invention provides antibodies to the polypeptides expressed by these genes and methods of use thereof.
