Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged ...

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 ...

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 ...

Francesca Storici consults at Tessera Therapeutics. She has received funding from the National Institutes of Health and the National Science Foundation. Your DNA is continually damaged by sources both ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

A research team led by Professor ZHAO Guoping at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a crucial mechanism that helps regulate DNA damage repair, ...

Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases like skin cancer, cells also have repair mechanisms that can fix ...
