Uniformed Services University Researchers Uncover Protection Mechanism of Radiation-Resistant Bacterium


3/21/2007 1:32:35 AM

Rockville, MD—Recent discoveries by researchers at the Uniformed Services University of the Health Sciences (USU) could lead to new avenues of exploration for radioprotection in diverse settings. Michael J. Daly, Ph.D., an associate professor in USU's Department of Pathology, and his colleagues have uncovered evidence pointing to the mechanism through which the extremely resilient bacterium Deinococcus radiodurans protects itself from high doses of ionizing radiation (IR). The results of the recent study, titled "Protein Oxidation Implicated as the Primary Determinant of Bacterial Radioresistance" were published in the March 20 edition of PLoS Biology.
