If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

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 ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

Scientists at the University of Copenhagen say they have located a previously unknown function for histones, which allows for an improved understanding of how cells protect and repair DNA damages.

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Each cell in our body experiences up to tens of thousands of DNA-damaging events per day, primarily from routine cellular maintenance or exposure to toxins in our environment. Despite the high ...

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature ...

Researchers have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. Researchers from the University of Birmingham have uncovered ...

Overcoming tumor resistance to chemotherapy drugs has long been a challenge for oncology clinicians and researchers. Now, a new study suggests that blocking a key protein, p300, may force damaged ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...
