New method paper:
Bennie Lemmens et al @scilifelab.se describe 3D-SPARK, a super-resolution microscopy method that maps changes in DNA replication nanostructures in response to genetic perturbations or drugs, linking spatial cell biology with DNA synthesis dynamics

Histone acetylation - not always about transcriptional activation: H4K16ac safeguards the genome replication program by repressing premature replication of heterochromatin. Well done Marta Milan! tinyurl.com/yuy9m8t3

🚀 Excited to share scPortrait! Led by Sophia Mädler & Niklas Schmacke w/ the Mann lab — a new @scverse tool for standardized single-cell image data. Enables ML-ready extraction, >1B cell processing, cross-omics, & cancer macrophage insights.

For decades, human genome editing has been limited to small, localized modifications.

Today, in a new paper published in @science.org , researchers from Arc's Hsu lab show that bridge recombinase technology is capable of large-scale genomic rearrangements in human cells.

New method 🚀: scEpi2-seq lets us read DNA methylation+histone marks in the same single cell. Found that methylation “memory” after replication depends on chromatin+histones, and TF promoters repressed by H3K27me3 carry distinct methylation. So stoked to share this as first+co-corresponding author 🎉

1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

🚀 Our new paper is out @natmethods.nature.com!

Kuffer & Marzilli engineered conditionally stable MS2 & PP7 coat proteins (dMCP & dPCP) that degrade unless bound to RNA, enabling ultra–low-background, single-mRNA imaging in live cells.

🧵1/14 Preprint thread! Can we predict a cell’s fate based on its dynamics? 🔮 Our new study unveils a framework for watching development unfold in real-time, revealing how a cell's shape and movement encode info about its future fate. 🔬📄 Preprint: tinyurl.com/4shf8v4x

Thrilled that our work is now finally out in Nature Comms!
rdcu.be/eG3vP

We reveal cryo-EM structures of the MRN complex bound to DNA & TRF2 - showing how DNA breaks are sensed and regulated at telomeres.
Fantastic work by first authors @yilanfan.bsky.social @filizkuybu.bsky.social & Hengjun!

Happy to share our latest research on the BRCA1-BRCTs now online.

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.

Studying cancer evolution needs multi-region or single cell seq for phylogenetics, right? Amazingly (I think!) we found single-sample bulk methylation suffices, via analysis of "fluctuating methylation". In @nature.com today led by brilliant @calumgabbutt.bsky.social www.nature.com/articles/s41...
Fluctuating DNA methylation tracks cancer evolution at clinical scale - Nature
Cancer evolutionary dynamics are quantitatively inferred using a method, EVOFLUx, applied to fluctuating DNA methylation.

Excited to share my postdoc work, out on bioRxiv today! Histones package DNA into nucleosomes to form the building blocks of chromatin, but how modular and programmable is this system? 1/9

Excited to share our lab’s latest preprint! We identify DDIAS as a novel single-stranded DNA-binding component of the TOPBP1–CIP2A complex, which acts in a mitotic DNA damage response pathway to protect chromosome integrity. Short summary below, and read it here: www.biorxiv.org/content/10.1...
DDIAS is a single-stranded DNA-binding effector of the TOPBP1-CIP2A complex in mitosis
DNA double-strand breaks and unresolved DNA replication intermediates are particularly dangerous during mitosis. Paradoxically, cells inactivate canonical DNA repair mechanisms during chromosome segre...
