A research group led by the University of Osaka has discovered that the DNA repair enzyme Polβ plays a crucial role in protecting the developing brain from harmful mutations. The study found that a ...

A new study shows that the DNA repair enzyme Polβ plays a vital role in protecting the developing brain from harmful ...

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 ...

Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer.

Studying families with multiple members who had breast cancer first led to the discovery of mutations in BRCA genes. Doctors ...

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

Without SUMO4, there is an excess of one type of signalling, disrupting other signals and preventing some repair proteins from reaching the damaged site. As a result, DNA repair fails.

DNA repair enzymes, such as the ligase shown here that joins broken DNA strands, scan replicating DNA in the nucleus. Particularly difficult cases are now known to be transported to the inner edge ...

A research team has discovered that accumulated DNA damage in the retina is a key contributor to age-related macular degeneration and that targeting specific retinal cell types may lead to ...
