A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

The study focused on rare DNA damage-repair (DDR) disorders, including Ataxia-Telangiectasia (A-T) and Bloom syndrome. These ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

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 ...

Recently, the research team led by Prof. Junjiu Huang from Sun Yat-sen University, in collaboration with Prof. Fenghua Liu’s team at Guangdong Women and Children Hospital, published a study titled ...

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 ...

Sleep isn’t just a luxury, it’s a vital process that helps our bodies repair and rejuvenate. Researchers have started to uncover how the quality and timing of sleep can affect more than just how ...
