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 ...

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 ...

Most of the cells in our body carry the genome, and those cells are constantly bombarded with environmental influences including UV rays, pollution, alcohol, and other exposures that can damage the ...

Cardiff University researchers discovered how a particularly severe type of DNA damage occurs, giving fresh insight into mutation mechanisms that contribute to cancer and inherited genetic diseases.

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged ...

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 ...
