| Outline of Final Research Achievements |
First of this study, we focus on Redox metabolism before and after irradiation in brain tumor stem-like cells (btSLCs). However we did not find noticeable difference between them. Next, we focus on energy metabolism in btSLCs. We found that btSLCs displayed lower oxidative phosphorylation activity and higher and lactate production than parental cells. Our findings also indicate that btSLCs metabolism plays an important role in maintaining radioresistance, and provide greater insight into the development of metabolic targeting radiotherapy to disrupt btSLCs.
