Application Number:	15/068,890
Patent Claims:	1. A method of sensitizing a patient with glioma to radiation therapy and/or chemotherapy, the method comprising administering to the patient with glioma propentofylline or a pharmaceutically acceptable salt thereof in an amount sufficient to inhibit TROY expression, but the amount is less than sufficient to substantially reduce viability of glioma cells. 2. The method of claim 1, wherein the glioma is glioblastoma. 3. The method of claim 2, wherein the glioma is invasive glioblastoma. 4. The method of claim 1, wherein the propentofylline is in a pharmaceutical composition comprising one or more pharmaceutically acceptable carriers. 5. The method of claim 1 further comprising administering to the patient with glioma a second pharmaceutical composition. 6. The method of claim 5, wherein the second pharmaceutical composition comprises at least one of the following: an antibody against TROY that inhibits TROY, Pyk2 shRNA, Rac1 siRNA, Dock180 siRNA, Dock7 siRNA, temozolomide and bevacizumab. 7. The method of claim 6, wherein the second pharmaceutical composition comprises temozolomide. 8. The method of claim 5, wherein the propentofylline and the second pharmaceutical composition are co-administered to the patient. 9. The method of claim 1 further comprising administering a therapeutically effective amount of radiation to the patient with glioma. 10. A method of sensitizing glioblastoma cells in a subject, the method comprising the steps of contacting the glioblastoma cells with a therapeutically effective amount of propentofylline or a pharmaceutically acceptable salt thereof in an amount sufficient to inhibit TROY expression, but the amount is less than sufficient to substantially reduce viability of glioblastoma cells, and further contacting the glioblastoma cells with another pharmaceutical composition. 11. The method of claim 10, wherein the glioblastoma comprises invasive glioblastoma. 12. The method of claim 10, wherein the pharmaceutical composition comprises the administration of one or more compounds selected from the group consisting of Pyk2 shRNA, Rac1 siRNA, Dock180 siRNA, Dock7 siRNA, temozolomide and bevacizumab. 13. The method of claim 12, wherein pharmaceutical composition comprises temozolomide. 14. The method of claim 10, wherein the pharmaceutical composition comprises a therapeutically effective amount of radiation. 15. The method of claim 10, wherein the glioblastoma cells are sequentially contacted with the therapeutically effective amount of propentofylline or a pharmaceutically acceptable salt thereof and the another pharmaceutical composition. 16. The method of claim 10, wherein the glioblastoma cells are substantially simultaneously contacted with the therapeutically effective amount of propentofylline or a pharmaceutically acceptable salt thereof and the another pharmaceutical composition.
