Abstract
Glioblastoma is a leader among the most malignant brain tumors with the average lifespan of patients around 9-12 months. For prevention and treatment of neuropathology, a variety of therapeutic and surgical approaches are being developed and improved, including radiation and chemical therapy methods. In our work, we investigated cytopathic effect of X-ray irradiation with application of metal oxides nanoparticles such as manganese oxide (MnO) on U87 human glioblastoma cells. We used the X-ray irradiation dose of 0.5, 4, 40 and 100Gy in combination with nanoparticles at the concentration of 0.5 ng/ml. The irradiation of glioma cell was carried out at the synchrotron radiation source VEPP-4. After cells treatments with nanoparticles for about 24h and radiation the results were assessed by MTT assay test with 106/ml cells densities. We demonstrate that preincubation of the glioblastoma cell lines U87 with MnO nanoparticles allows reducing dose of irradiation. This combination of nanoparticles and X-ray irradiation provides new possibilities for the treatment of brain tumors.
