Proper organelle regulation during mitosis is a must, but how do membrane-less condensates like PML bodies behave during cell division? In work led by Eric Aird, we found the balance of speckled proteins SP110 & SP100 to be the key. doi.org/10.1038/s415...

Many genome-editing tools work by cutting DNA - but the shape of the cut matters. Using genome-wide screening, we show ERCC6L2 is specifically required to maintain repair fidelity at staggered DNA breaks, but not at blunt ends.

Excited to share our new Nature study! 🧬

We (sidrituruci.bsky.social et al) discovered that CFAP20 helps clear stalled RNAPII, preventing harmful clashes with DNA replication machinery. This protects cells from R-loops and genome instability.

New research group leader for functional genomics Molecular biologist Matthias Muhar becomes part of the MPI-CBG faculty

New research group leader @matthiasmuhar.bsky.social joins @mpi-cbg.de! 🥳 With his group "Functional genomics of proteome remodeling,” Matthias wants to pursue high-throughput genetic studies to understand how protein turnover is regulated. Welcome, Matthias! www.mpi-cbg.de/news-outreac...

Congrats to Moritz Schlapansky, who successfully defended his PhD thesis on Friday! You can read his work on "scOUT-seq" profiling of single cell transcriptomes + editing outcomes in millions of cells and living mice at www.biorxiv.org/content/10.1...

Directed evolution of compact RNA-guided nucleases for homology-directed repair in mammalian cells RNA-guided nucleases enable DNA editing and offer promise for treating genetic diseases, particularly when used for precise sequence replacement. However, many of the most effective enzymes, such as S...

Sometimes #Cas9 is too dang big. But mini Cas proteins are bad at both NHEJ & HDR. PhD student Fedor Gorbenko used mammalian cell evolution for *HDR* to make REALLY super #Cas12f1 and #TnpB. As good as or better than Cas9! Base editors included! www.biorxiv.org/cgi/content/short/2025.10.27.684765v1

Thanks to CRISPR/Cas technology, researchers can precisely edit genetic material to treat hereditary diseases. To achieve this, they need to identify undesirable cuts in the genome at an early juncture. Pioneer Fellow Lilly van de Venn is developing such testing methods. ethz.ch/en/news-and-...

Cell-stereotyped DNA repair outcomes are widespread during genome editing Genome editing outcomes are governed by DNA repair pathways that vary with cell type and state. We developed scOUT-seq (single-cell Outcomes Using Transcript sequencing), a scalable approach that join...

Ever noticed that #CRISPR editing results differ between cells? Awesome PhD student Moritz Schlapansky developed "scOUT-seq" to measure single cell transcriptomes + editing. 1.2 million cells, 74 cell types, living 🐭. Cell subtypes differ wildly from bulk average! www.biorxiv.org/content/10.1...

On that note: hello world! My new lab on genetics of proteome remodeling is starting at the incredible MPI-CBG. We have big plans and open positions for PhD students and an RA. Apply now (!) at imprs.mpi-cbg.de and tinyurl.com/2vywj6f6 respectively.

If you are interested in a PhD in the area of "Mechanisms of Genome Stability" and "Functional Genomics of Proteome Remodelling," apply now for a PhD @mpi-cbg.de! Overview of all participating RGLs: imprs.mpi-cbg.de/5761/researc...

Just out in @science.org: Together with the lab of @wilhelmpalm.bsky.social, we used sequential in-vitro/in-vivo CRISPR screens to decipher metabolic adaptations in tumors. We find that acidosis is a dominant factor that shapes energy metabolism and stress resilience. www.science.org/doi/10.1126/...

Congrats to first author Venda for putting it all together! This project was a great collaboration with the @titiasixma.bsky.social lab who helped us give structural meaning to our observations.

Mitotic single-stranded DNA suppression by DDIAS Incomplete DNA replication and chromosome breakage during mitosis pose major threats to chromosome segregation. The CIP2A-TOPBP1 complex acts to mitigate this peril, but its exact role is not yet unde...

Exciting times ahead!

Today marks the first day of the Loeff Lab at Leiden University Medical Center in the Netherlands 🇳🇱. I’m thrilled to begin this new adventure and continue exploring microbial defense mechanisms and their applications through an integrative structural biology approach.

NASP modulates histone turnover to drive PARP inhibitor resistance - Nature PARP inhibitor treatment triggers histone release from the chromatin in cancer cells; consequently, targeting the histone chaperone NASP renders cells vulnerable to PARP inhibition.

Thrilled to see this “veritable tour de force” led by John_C_Fielden from Jacob Corn lab out @nature.com, rdcu.be/ehd4E. This @erc.europa.eu funded project uses #CRISPRi to systematically scan 548 DDR genes for synthetic lethal interactions, ~150,000 pairwise combinations!

New #preprint from the lab! Do you want to see the invisible? So did we! When DNA genomes get broken, cells somehow find related sequences to fix the break. But how do they find it? We developed a way to look at sequence *search*, not just sequence usage.
