Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

Researchers have discovered how the protein XPD detects severe DNA damage and controls its repair. The XPD protein is a central component of our body's own "DNA repair team," known as nucleotide ...

The human genome is contained within the nucleus of cells. The genome is well protected, but many things can cause DNA damage, including aging, some drugs, and environmental factors like UV rays or ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

Poly(ADP‐ribose) polymerases (PARPs) are a family of enzymes that play a crucial role in maintaining genomic integrity by detecting DNA damage and facilitating its repair. By catalysing the covalent ...

Proteins PIF1 and PCNA gather at sites of DNA damage in SETX-deficient cells, indicating activation of the BIR repair system. LA JOLLA, CA—The DNA inside our cells is constantly being damaged, and one ...

Deinococcus radiodurans is renowned for its extraordinary resistance to ionising radiation and other environmental stresses. This bacterium employs a combination of passive and active mechanisms to ...

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 ...
