New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that TDP43 controls a key DNA repair process, but when the protein becomes ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

A protein best known for driving cancer growth also helps damaged tumor cells survive by repairing their DNA, according to a ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
