Outline of Final Research Achievements |
We analyzed the level of IR-induced cell death in neural stem and glioblastoma cells. To measure the type of cell death, i.e. necrosis and apoptosis, after IR, we carried out Acridine Orange and Ethidim Bromide assay. We observed that neural stem cells show greater IR sensitivity than glioblastoma cells. Imporantly, neural stem cells preferentially undergo apoptosis after IR. Further, we observed greater p53 phosphorylation in neural stem cells compared with that in glioblastoma cells. In addition, we performed a preliminary study on the effect of bystander in these cells. We found less effect of bystander in terms of cell death in neural stem cells.
