Summary:
Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked, researchers at Duke University Medical Center have found. The researchers also identified a method that appears to block the cells' ability to activate the repair switch following radiation treatment. This finding may lead to the development of therapies for overcoming radiation resistance in brain cancer as well as other types of cancer, the researchers said.
Commentary: Hopefully this finding will increase the effectiveness of radiation and enable it to successfully eliminate different types of cancers and tumors.
