Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer
In both cancer cell lines and in mice, blocking critical DNA repair mechanisms could improve the effectiveness of radiation therapy for highly fatal brain tumors called glioblastomas, research shows. Radiation therapy causes double-strand breaks in DNA that must be repaired for tumors to keep growing. Scientists have long theorized that if they could find a way to block repairs from being made, they could prevent tumors from growing or at least slow down the growth, thereby extending patients' survival.<img src="http://feeds.feedburner.com/~r/sciencedaily/~4/lJp17tcezGk" height="1" width="1"/>
