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 ...

UC Riverside researchers identify a new mitochondrial DNA adduct that disrupts energy production and triggers stress-response ...

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 ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing ...

The findings may have important implications for diseases linked to mitochondrial dysfunction. A newly identified form of DNA damage inside mitochondria, the small structures that supply energy to our ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

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 ...
