A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which ...

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 ...

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 ...

Damaged DNA can escape from one human cell and infiltrate another. Like prisoners tunneling out of jail, this DNA travels via tubelike structures between neighboring cells, scientists report May 19 in ...

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 that ...

Migrating newborn neurons suffer routine double-strand DNA breaks from physical stress during brain development.

Every human cell packs roughly two meters of DNA into a nucleus only six micrometers wide. That ratio, confirmed by ...

Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell ...

The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...

Stretched into a single line, the DNA packed inside one human cell would reach roughly two meters, yet it folds into a nucleus just 5 to 10 micrometers wide. That compression ratio, on the order of ...
