Cancer cells' DNA repair disrupted to increase radiation sensitivity

ScienceDaily (Dec. 1, 2011) — Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells' sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research.Researchers would to like see their laboratory findings -- published in the journal's Dec. 5 print edition -- lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...
