Maintaining the chemical integrity of DNA in the face of assault by oxidizing agents is a constant challenge for living organisms. Base-excision repair has an important role in preventing ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

Jan. 15, 2025 — 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.

Manipulating DNA repair proteins can significantly influence base editing efficiency and outcomes. Inhibiting uracil N-glycosylase (UNG) and DNA ligase 3 (Lig3) ...

, have, for the first time, been able to view how this repair machinery prioritizes fixing these thousands of instances of DNA damage. They achieved this feat using their novel sequencing technique, ...

These proteins repair DNA damage from UV radiation using light. “They’re very good at using almost every single photon they catch,” says Thomas Lane at the German Electron Synchrotron (DESY).
