Our DNA undergoes constant damage and repair. The most severe damage happens when the DNA breaks into two pieces, known as a double-strand DNA break. It creates two loose DNA ends that, if left unfixed, can lead to cell death. Researchers from the Biotechnology Center (BIOTEC) of the Dresden University of Technology have now answered the long-standing question of what keeps the broken DNA ends from being separated.

Our DNA is constantly exposed to damaging factors that can lead to aging and age-related diseases such as cancer. PARP1 is an important enzyme that facilitates the response to DNA damage by attaching chemical groups called ADP-ribose to proteins. Published in Molecular Cell, a new study by the Matic group at the Max Planck Institute for the Biology of Ageing has discovered a second, slower wave of PARP1 activity that regulates DNA repair in a more gradual way.
