Most people associate sunburns with DNA damage -- it's what we've been taught in textbooks and by dermatologists for years.

For decades, we’ve believed the bright redness of sunburn — along with its irritating sting and peeling skin — was the result of ultraviolet (UV) radiation wreaking havoc on DNA. But now, a new study ...

Genetic instability can arise as a function of hypoxia-mediated resistance to apoptosis and decreased ... concerning the sensing and repair of DNA damage under experimental conditions of acute ...

They investigated a form of apoptosis caused by hydroxy radicals formed in the ... that treating cells directly with hydrogen peroxide caused DNA damage responses and growth arrest, but the cells didn ...

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 ...

At this point, DNA repair systems recognize it as DNA damage and trigger a form of permanent cell cycle arrest called replicative senescence, which may lead to cell death called apoptosis. 5 This ...

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 ...

"Sunburn damages the DNA, leading to cell death and inflammation. So the textbooks say. But in this study we were surprised to learn that this is a result of damage to the RNA, not the DNA that ...
