A protein long studied for its role in amyotrophic lateral sclerosis and frontotemporal dementia now appears to serve a second, equally critical function, safeguarding the integrity of human DNA.

New research into how the body repairs damaged DNA is opening fresh debate about how long humans could live. A newly studied protein may play a key role in slowing aging and preventing disease.

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

Study establishes for the first time that defective DNA repair may be the major driver of several clinical features associated with a subset of patients with 22q11.2 distal deletion syndrome ...

A protein found in bowhead whales, one of the longest-living mammals on Earth, could help improve how human cells repair DNA, according to new research from scientists at the Albert Einstein College ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

In addition to Lander and Zerio, authors of the study, "Human polymerase θ helicase positions DNA microhomologies for double-strand break repair," include Yonghong Bai, Brian A. Sosa-Alvarado and ...

A protein in bowhead whales, CIRBP, enhances DNA repair in human cells, possibly extending lifespans. Learn about this study ...
