New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...
Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

Cancer’s most notorious protein MYC quietly repairs tumor DNA damage behind the scenes — scientists say blocking the trick could multiply what chemo already does
Chemotherapy drugs are designed to shatter tumor DNA so thoroughly that cancer cells cannot survive. But one of the most ...
The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...
Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...
DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...
Naked mole-rats are well known for both their wrinkly appearance and for their unexpectedly long lives. The source of this extended lifespan has been under scrutiny for decades. While many rodents are ...
