Narrator: This is Science Today. 'Smart Bomb' therapy for cancer, in which antibodies are used to carry doses of radiation directly to tumor cells, is getting a boost from researchers at the University of California, Davis. Dr. Claude Meares and his team have developed a new method to permanently bind the smart bomb treatment to antibodies.
Meares: The small molecule that targets cancer has to stay stuck on the cancer cell permanently or preferably permanently. And we have found a way to do that - engineering the receptor that would catch this small radioactive molecule and also, synthesizing an appropriate set of molecules that would go together permanently once they ran into ran into each other, but would not stick to anything else.
Narrator: And by having such a direct target, normal tissue can be spared.
Meares: This new approach delivers radiation to the cancer and not to other normal cells in the body much more efficiently, so we're very excited about its future.Narrator: For Science Today, I'm Larissa Branin.
