KappaBle mice: illuminating NF-kB
![](/en/news-and-events/d-biol-news/2022/06/kappable-mice-illuminating-nf-kb/_jcr_content/pageimages/imageSmall.imageformat.contentteaser.161059982.png)
A recent "Mucosal Immunology" paper by the Kopf group (IMHS) describes the generation of KappaBle fluorescent reporter animals that allow sensitive, low background, high-throughput detection of the activity of transcription factor NF-kB in all cell types.
Mre11-Rad50 oligomerization promotes DNA double-strand break repair

A recent “Nature Communications” paper by the Peter and Cejka groups (IBC, ETH/IRB) reveals how the oligomerization of a conserved protein complex is critical for DNA damage signaling, DNA repair and telomere maintenance, with potential implications for cancer predisposition and chemoresistance.
METALIC reveals interorganelle lipid flux in live cells by enzymatic mass tagging

A recent study in "Nature Cell Biology" by the Peter group (IBC) and the former Kornmann group (now at the University of Oxford), demonstrates a new versatile strategy to track the movement of lipids between organelles in vivo, using a combination of enzyme-based chemical modification and mass spectrometry.
AI-driven discovery of novel chemical structures by mass spectrometry
