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

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 ...

Failure to repair DNA damage can result in DNA lesions and mutations that are a driving factors in cancer development. Recent work has identified a function for DNA damage repair mechanism beyond ...

Many people lather up with sunscreen or cover up with hats to protect themselves from the sun’s harmful rays. These added layers help to shield the skin from ultraviolet (UV) light, which damages DNA ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

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 ...

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 ...

Tardigrades, often called water bears or moss piglets, are microscopic creatures that can survive just about anything: boiling heat, freezing cold and crushing pressure. 2 In fact, tardigrades are the ...

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 ...

LIG4 syndrome is an exceptionally rare disorder caused by a genetic mutation that prevents the body from repairing damaged DNA. When you purchase through links on our site, we may earn an affiliate ...

Anglia Ruskin University (ARU) provides funding as a member of The Conversation UK. Sleep isn’t just a luxury, it’s a vital process that helps our bodies repair and rejuvenate. Researchers have ...
