Аннотация

A binary cytopathic effect (CPE%) of synchrotron radiation (SR) and manganese oxide nanoparticles (MnO NP) on human glioblastoma U87MG, U-251MG, and A-172 cell lines was studied in vitro. After incubation of the cells with MnO NP at a concentration of 5 and 50 µmol for 18–24 h, irradiation of glioblastoma cells at the source of SR VEPP-4 was carried out. X-ray irradiation doses 0, 1, 2, 4 Gy were used. The results were estimated using a light microscopy, determination of CPE% on the counter (Countess, Invitrogen), and the clonogenic test. It was revealed that the preliminary incubation of glioblastoma cell lines with MnO NP causes an increase in CPE of external SR at a dose 1, 2, and 4 Gy on the glioblastoma cells by 25, 50, and 100%. This effect allows to reduce the radiation dose by 2–3 times, maintaining the efficiency of the effect. At the same time, the period of vital activity of tumor cells under a combined effect of SR and NP is reduced by 18–36 h. Probably, a synergism of the combination of MnO NP and SR will provide new opportunities for the development of a model for the treatment of brain tumors.
