While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic letters before it divides.

A research team from the University of California (UC), Irvine, has revealed a previously unknown mechanism that triggers an inflammatory immune response in cells when their DNA is damaged. The ...

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 ...

New research from the Kind Group at the Hubrecht Institute sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...

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 ...
