At Last, A Reason Why Stress Causes DNA Damage

Duke Medicine News and Communications:

For years, researchers have published papers that associate chronic stress with chromosomal damage.
Now researchers at Duke University Medical Center have discovered a mechanism that helps to explain the stress response in terms of DNA damage.
“We believe this paper is the first to propose a specific mechanism through which a hallmark of chronic stress, elevated adrenaline, could eventually cause DNA damage that is detectable,” said senior author Robert J. Lefkowitz, MD, James B. Duke Professor of Medicine and Biochemistry and a Howard Hughes Medical Institute (HHMI) investigator at Duke University Medical Center.
The paper was published in the August 21 online issue of Nature.
