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 ...

Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic letters before it divides.

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

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

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

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 ...

Once failed in high school chemistry due to a teacher’s judgement, Tomas Lindahl later reshaped the same discipline. Awarded the 2015 Nobel Prize in Chemistry for his pioneering DNA repair research, ...

As people age, their immune systems deteriorate. This makes them more susceptible to infections and can mean that vaccines ...

In addition to its effects on DNA, magnesium has been identified as a cofactor in over 300 enzyme systems in the body, including those that regulate blood pressure, control blood glucose levels, and ...
