Radiation Biology Lab
Machine-translated · View original
A radiation biology lab that explores, at the molecular level, how radiation works and what effects it has.

AboutAbout the lab
Exploring how radiation affects living organisms
The Radiation Biology Lab conducts basic research on radiation therapy for cancer and research on the effects of low-dose radiation on living organisms.
Focusing on ATM and DNA-PK, which are DNA double-strand break repair enzymes, the lab studies radiosensitization of cancer, prediction of radiosensitivity, and radioprotection of normal tissue.
The lab also aims to clarify at the molecular level how low-dose and low-dose-rate radiation causes vascular lesions such as myocardial infarction and cerebral infarction.
Key terms
- DNA double-strand break repair enzymes
- Enzymes that rejoin the two strands of DNA broken by radiation or other causes. They include ATM and DNA-PK.
- Cancer stem cells
- Cells in cancer tissue that are thought to keep producing cancer cells while replicating themselves.
- G0 phase
- A state in which a cell has left the cell division cycle and has stopped proliferating.
NewsLab news
Paper published reporting the effects of the LDHA inhibitor oxamate on glioblastoma cells
Paper published reporting the relationship between FDX1 and radioresistance in glioblastoma cells under severe hypoxia
ResearchResearch themes
The lab studies the basics of radiation therapy for cancer and the effects of low-dose radiation on the body. Focusing on enzymes that repair breaks in both strands of DNA, it investigates their relationship with radioresistance and radiosensitivity.
