Research methods: method of comet electrophoresis of individual cells (Comet assay); cytogenetic. The level of genomic instability in irradiated peripheral blood lymphocytes of 10 people (control group) and 20 glioblastoma patients (examination group) was compared. Features of the modifying effect of glioma on the development of radiosensitivity in patients were revealed: after irradiation, in comparison with the control group, a statistically significant (p < 0.001) increase in the frequency of aberrant cells in peripheral blood lymphocytes of patients with glioblastoma was found, which indicates an increase in chromosomal instability under the influence of the tumor; under the joint influence of radiation and glioblastoma, a statistically significant increase in the frequency of cells in a state of apoptosis was recorded It has been established that exposure to glioblastoma leads to an increase in the level of chromosomal aberrations and activates the process of apoptosis, which is a key mechanism for regulating the development of genomic instability in somatic untransformed cells of individuals with glioblastoma Product Description popup.authors Hlavatskyi Oleksandr Ya.
