A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

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 ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, ...

Macquarie University researchers have discovered a naturally occurring protein found in human cells plays a powerful role in repairing damaged DNA—the molecule that carries the genetic instructions ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

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 ...
