The invention provides generally a method of monitoring, diagnosing, prognosing and treating glioma. Specifically, the invention provides for three (3) prognostic subclasses of glioma, which are differentially associated with activation of the akt and notch signaling pathways. Tumor displaying neural or proneural PN lineage markers (including notch pathway elements) show longer median patient survival, while the two remaining tumor markers Prolif and Mes are associated with shortened survival. Tumors classified in this manner may also be treated with the appropriate PN- Prolif- or Mes-therapeutic corresponding to the subclassification in combination with anti-mitotic agents, anti-angiogenic agents, Akt antagonists, and neural differentiation agents. Alternatively, the invention also provides for method of prognosing and diagnosing glioma with a two-gene model based on the expression levels of PTEN and DLL3.

The present invention provides novel methods and kits for diagnosing the presence of cancer within a patient, and for determining whether a subject who has cancer is susceptible to different types of treatment regimens. The cancers to be tested include, but are not limited to, prostate, breast, lung, gastric, ovarian, bladder, lymphoma, mesothelioma, medulloblastoma, glioma, and AML. Identification of therapy-resistant patients early in their treatment regimen can lead to a change in therapy in order to achieve a more successful outcome. One embodiment of the present invention is directed to a method for diagnosing cancer or predicting cancer-therapy outcome by detecting the expression levels of multiple markers in the same cell at the same time, and scoring their expression as being above a certain threshold, wherein the markers are from a particular pathway related to cancer, with the score being indicative or a cancer diagnosis or a prognosis for cancer-therapy failure. This method can be used to diagnose cancer or predict cancer-therapy outcomes for a variety of cancers. The markers can come from any pathway involved in the regulation of cancer, including specifically the PcG pathway and the “stemness” pathway. The markers can be mRNA, microRNA, DNA, or protein.

The present invention relates to chimeric transmembrane immunoreceptors, named “zetakines,” comprised of an extracellular domain comprising a soluble receptor ligand linked to a support region capable of tethering the extracellular domain to a cell surface, a transmembrane region and an intracellular signalling domain. Zetakines, when expressed on the surface of T lymphocytes, direct T cell activity to those specific cells expressing a receptor for which the soluble receptor ligand is specific. Zetakine chimeric immunoreceptors represent a novel extension of antibody-based immunoreceptors for redirecting the antigen specificity of T cells, with application to treatment of a variety of cancers, particularly via the autocrin/paracrine cytokine systems utilized by human malignancy. In a preferred embodiment is a glioma-specific immunoreceptor comprising the extracellular targetting domain of the IL-13Rα2-specific IL-13 mutant IL-13(E13Y) linked to the Fc region of IgG, the transmembrane domain of human CD4, and the human CD3 zeta chain.

One of the impediments to the treatment of some human brain tumors (e.g. gliomas) has been the degree to which they expand, migrate widely, and infiltrate normal tissue. We demonstrate that a clone of multipotent neural progenitor stem cells, when implanted into an experimental glioma, will migrate along with and distribute themselves throughout the tumor in juxtaposition to widely expanding and aggressively advancing tumor cells, while continuing to express a foreign reporter gene. Furthermore, drawn somewhat by the degenerative environment created just beyond the infiltrating tumor edge, the neural progenitor cells migrate slightly beyond and surround the invading tumor border. When implanted at a distant sight from the tumor bed (e.g., into normal tissue, into the contralateral hemisphere, into the lateral ventricles) the donor neural progenitor/stem cells will migrate through normal tissue and specifically target the tumor cells. These results suggest the adjunctive use of neural progenitor/stem cells as a novel, effective delivery vehicle for helping to target therapeutic genes and vectors to invasive brain tumors that have been refractory to treatment.
