Real-time imaging shows that bacterial resilience to antibiotics is not caused by a few ‘persisters’, but is a ...

The researchers observed that a specific strain of the bacteria Escherichia coli produces a toxic molecule, called colibactin, which damages the DNA of human cells. The new work has found ...

Disinfectants induce oxidative damage in bacteria, but a single mutation triggers the expression of genes that help the ...

“Wild stuff does happen.” The trillions of bacteria in our bodies regularly exchange DNA with each other, but the idea that their genes could end up in human DNA has been very controversial. In 2001, ...

The genetic connections between DNA repair pathways and human cancer predisposition have fueled interest in the proteins that recognize and repair specific sites of DNA damage. The repair enzymes are ...

As previously mentioned, one important DNA damage response (DDR ... levels of this radiation to reach the planet's surface. Bacteria and several other organisms also possess another mechanism ...

Antibiotic resistance is a global public health crisis responsible for more than a million deaths annually. By 2050, the World Health Organization estimates it could surpass cancer and heart disease ...

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 ...

"We hypothesized that the binding by these adhesins allows bacteria to produce the genotoxin colibactin nearby epithelial ...

Get Instant Summarized Text (Gist) DNA damage in healthy cells can persist unrepaired for years, challenging traditional views on mutation formation. This persistence allows multiple opportunities ...

"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 ...
