Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a ...

Now, scientists at the University of California, Riverside, may have found a way to halt the damage before it begins. The ...

Researchers have designed a chemical probe to bind damaged mitochondrial DNA, halting the enzymatic processes that lead to ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

Researchers discovered a previously unknown function of RNA, potentially opening the door to new ways to treat cancer and neurodegenerative diseases.

Cells are constantly subjected to DNA damage from a range of internal and environmental sources. It is estimated that cells can experience as many as 100,000 DNA lesions per day. One of the most ...

Recently, numerous findings have helped clarify the mechanisms by which DNA damage may mediate neuronal dysfunction. Broadly, these are lessons learned through both DNA damage repair disorders and ...

Taking melatonin supplements won’t erase existing DNA damage, but it might help bolster the body’s natural repair system.
