Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Medical scientist Eduardo Marbán – then at Johns Hopkins and now Cedars-Sinai – found that heart progenitor cells also have a special mechanism where they send out sacs, known as exosomes, which carry ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

New Houston Methodist research has revealed that a protein associated with neurodegenerative diseases such as dementia and amyotrophic lateral sclerosis (ALS) also plays a role in regulating DNA ...

Naked mole-rats are one of nature's most extraordinary creatures. These burrowing rodents can live for up to 37 years, around ten times longer than relatives of a similar size. But what is the secret ...

Using comparative molecular biology with human cGAS – which actually inhibits DNA repair – the scientists found that the naked mole-rat's enzyme has four key changes that facilitate the important work ...

Naked mole-rats are well known for both their wrinkly appearance and for their unexpectedly long lives. The source of this extended lifespan has been under scrutiny for decades. While many rodents are ...

A clump of proteins seems to be in charge of the level of DNA repair that takes place in our bodies, determining how fast mutations accumulate in our cells over a lifetime – and might thus affect our ...

A research team has successfully identified a novel DNA damage repair pathway in human cells. This study is the first to discover that proteins present in the nuclear membrane of cells directly ...

A retrospective study found that patients with mismatch repair (MMR)-deficient advanced or recurrent endometrial cancer had numerically longer overall survival (OS) than those with MMR-proficient ...

Purpose: This study aimed to examine pathogenic variations in three families clinically diagnosed with suspected Lynch syndrome (LS). Methods: Three probands clinically diagnosed suspected LS were ...
