Discovery of new protein important in breast cancer gene's role in DNA repair

For years, researchers have known that under normal conditions, the breast cancer protein BRCA1 orchestrates the repair of damaged DNA, but the details of just how BRCA1 moves to the damaged site and recruits the right nuclear repairmen for DNA restoration remains a mystery.

MRSA study suggests strategy shift needed to develop effective therapeutics

USA300-the major epidemic strain of methicillin-resistant Staphylococcus aureus (MRSA) causing severe infections in the United States during the past decade-inherits its destructiveness directly from a forefather strain of the bacterium called USA500 rather than randomly acquiring harmful genes from other MRSA strains.
