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 ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

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 at the University of Würzburg, led by Caroline Kisker in cooperation with Claudia Höbartner, discovered how the protein XPD detects a severe DNA damage and controls its repair. The XPD ...

A single molecule of DNA (not directly visible) is captured using microscopic beads (the large circles). Each of the red, green or yellow dots moving between the beads represent a FANCD2I-FANCI ...

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 ...

LONDON (Reuters) - Drinking alcohol produces a harmful chemical in the body which can lead to permanent genetic damage in the DNA of stem cells, increasing the risk of cancer developing, according to ...

Japanese researchers discovered that hair graying and melanoma share a surprising cellular origin. When DNA damage strikes melanocyte stem cells, they may undergo a protective process called ...
