New discovery could lead to better results for patients undergoing radiation

More than half of cancer patients undergo radiotherapy, in which high doses of radiation are aimed at diseased tissue to kill cancer cells. But due to a phenomenon known as radiation-induced bystander effect (RIBE), in which irradiated cells leak chemical signals that can travel some distance to damage unexposed healthy cells, many suffer side-effects such as hair loss, fatigue and skin problems. This bystander effect may also make targeted cells resistant to radiation treatment, research suggests. A new CU Boulder study, published in the journal Nature, sheds new light on the precise mechanism behind RIBE, identifying both a protein released by irradiated cells and the pathway it takes to influence healthy ones. Ultimately, researchers hope it could lead to a medication patients could take before radiation treatment.
