Our DNA is under constant threat. Chemicals, radiation and the everyday errors of cell division all damage it, and if left ...

A new way for hard-to-treat cancer cells to protect themselves from being killed by anticancer drugs has been found. The ...

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 ...

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 drug already safe for humans reduces disease-linked early features of Alzheimer’s in a lab model of the disease, say ...

Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself DURHAM, N.C. -- Like its viral cousins, a somewhat parasitic DNA sequence called a ...

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 ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere.
