A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential ...

Discovery reshapes understanding of how tumor cells repair broken DNA, pointing toward more precise cancer therapies.

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

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 new study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most powerful genetic "on switches" in cancer cells, called super-enhancers, drive ...

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 ...

Researchers at Genentech Inc. and UC Davis have worked out the structure of the RAD51 complex, which repairs breaks in DNA. When DNA experiences a double-strand break, enzymes trim back one of the two ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
