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 ...

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 ...

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 ...

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 ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

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 ...

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 ...

RIVERSIDE, Calif. -- 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 ...
