Abstract: A diagnostic method for predicting whether a human tumor will be sensitive or resistant to treatment with tivozanib (AV-951) is disclosed. The method is based on measurement of macrophage content in a tissue sample from a tumor. Measurement of macrophage content can be based on analysis of macrophage marker gene expression, e.g., by RNA analysis or immunohistochemistry.

Abstract: The present invention provides a family of binding proteins that bind and neutralize the activity of hepatocyte growth factor (HGF), in particular human HGF. The binding proteins can be used as diagnostic and/or therapeutic agents. With regard to their therapeutic activity, the binding proteins can be used to treat certain HGF responsive disorders, for example, certain HGF responsive tumors.

Abstract: Chimeric nonhuman mammals useful as inducible spontaneous cancer models are disclosed. The nonhuman mammals are obtained by introducing one or more genetically modified embryonic stem (ES) cells into an early stage embryo, and then implanting the manipulated embryo into a surrogate mother. The ES cells contain a recombinant oncogene, and also may contain a genetic mutation that deletes or inactivates a tumor suppressor gene. Models of different types of cancer are produced by introducing different combinations of genetic mutations into the ES cells that are introduced into the early stage embryo.

Abstract: A diagnostic method for predicting quantitatively whether a human tumor will be responsive or resistant (non-responsive) to treatment with the VEGF inhibitor, tivozanib (AV-951), is disclosed. The test is based on application of an algorithm to measurements of expression levels of the genes in a predictive gene set.

Abstract: A method of producing a tumorigenic mouse cell, the tumorigenicity of which depends on a recombinant gene of interest is disclosed. The method involves: (a) providing a conditionally tumorigenic mouse cell containing a recombinant oncogene operably linked to an inducible promoter, wherein (i) expression of the recombinant oncogene is necessary and sufficient for the tumorigenicity of the tumorigenic mouse cell, and (ii) the inducible promoter is in the uninduced state; and (b) introducing into the cell a recombinant gene of interest that functionally complements the oncogene, thereby restoring tumorigenicity without expression of the inducible recombinant oncogene. Also disclosed is a method of testing a compound for anti-tumor effects.

Abstract: The disclosure provides a method for identifying cancer tissue sensitive to treatment with an inhibitor of Notch receptor activation. The method comprises determining the level of HeyL gene expression in a sample derived from the cancer tissue, wherein an elevated level of HeyL gene expression alone in the sample indicates sensitivity to the cancer tissue to treatment with an inhibitor of Notch receptor activation.

Abstract: The invention provides methods using N3-pyridyl-thiamine compounds and pharmaceutical compositions comprising N3-pyridyl-thiamine, which are especially useful for preventing or reducing tumor growth in vivo. The invention is also directed to the benefits of reducing thiamine concentrations, e.g., by means of a thiamine reduced diet, as an effective step in a therapeutic regime for patients treated with N3-pyridyl-thiamine.
