Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Researchers have discovered how a metabolite involved in repairing damaged DNA not only controls a person’s sensitivity to cancer therapies but can also protect healthy tissues from damage. The ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

New research led by researchers at the University of California, San Diego (UCSD), School of Medicine, reveals a novel map that depicts the human body’s system for addressing and repairing DNA ...

DNA can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from ...

Researchers have uncovered a novel mechanism for repairing DNA damage in neurons The study reveals a protein complex that initiates a pathway to repair DNA breaks induced by neuronal activity “More ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

Egg cells need stamina: They are formed in a woman's body before birth and have to be on standby for decades to possibly be ...

Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases like skin cancer, cells also have repair mechanisms that can fix ...
