Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

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 ...

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding ...

A new single-cell profiling technique has mapped pre-malignant gene mutations and their effects in solid tissues for the ...

Mutations in the tumor suppressor TP53 are a common cause of cancer, making the altered protein an attractive target for ...

A new long-read sequencing technique has helped researchers investigate how DNA mutations arise in a variety of contexts. A collaboration of researchers led by NYU Langone Health and NYU Grossman ...

A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

Lung cancer cases are on the rise in non-smokers around the world, and air pollution could be an insidious, contributing factor. A genome study has now found that outdoor smog and soot are strongly ...
