Type:
A radiosensitizer is an agent that makes cancer cells more sensitive to the damaging effects of radiation therapy. By using a radiosensitizer, clinicians aim to enhance the effectiveness of radiation treatment by either increasing the damage incurred by tumor cells or by interfering with the cancer cells’ repair mechanisms. This can potentially allow for lower doses of radiation, reduced side effects, or improved treatment outcomes.
Pathways that help Radiosensitivity: downregulating HIF-1α, increase SIRT1, Txr
