Medically reviewed by Marla Anderson, MD Key Takeaways Free radicals are unstable molecules that can damage DNA, leading to ...

New research published in Nature Communications has linked a normal cellular process to an accumulation of DNA mutations in ...

Free radicals are highly reactive molecules that are missing an electron. They get a bad rap, but could they actually have any benefits?

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 ...

Cancer cells with a cell nucleus that is easily deformed are more sensitive to drugs that damage DNA. These are the findings of a new study by researchers at Linköping University in Sweden.

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Cell-free DNA (cfDNA) analysis is transforming precision medicine, offering a non-invasive window into the body, particularly in the context of cancer. This journal collection, hosted by npj Precision ...

Dr. Debu Tripathy discusses recent research on the use of circulating tumor DNA in metastatic breast cancer care. Circulating tumor DNA, also referred to as ctDNA, are small pieces of DNA that are ...
