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

scEpi2-seq: a method for simultaneous single-cell profiling of DNA methylation and histone modifications. @jervdberg.bsky.social @hubrechtinstitute.bsky.social www.nature.com/articles/s41...

🧬 Hubrecht researchers have developed a method that can detect DNA methylation and histone modifications simultaneously in single cells. They can now for the first time study how their interaction influences gene activity. https://www.nature.com/articles/s41592-025-02847-4  @jervdberg.bsky.social

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 🎉

The latest work from ours and @vram142.bsky.social lab is out! True teamwork to visualize nascent chromatin with strand resolution, using a fully reconstituted system. Very proud of superstar-PhD student Bruna, and @palindromephd.bsky.social. Learning so much from Vijay’s amazing technologies! RT

Big shoutout to this amazing work from our colleagues in the Knipscheer lab. Congratulations on discovering and dissecting yet another new molecular mechanism that keeps our genome safe! 👏🍾

Excited our paper is out! G-quadruplex (G4) unwinding via an intricate G-loop assembly and disassembly mechanism maintains genome integrity. Pioneered by Koichi Sato with great collaborators Jing Lyu and @simonelsasser.bsky.social Check it out: www.science.org/doi/10.1126/science.adr0493 🧵(1/4)

We found G4s are recognized as DNA lesions leading to homology-directed invasion of RNA opposite the G4 to form a G-loop structure. This G-loop initiates G4 unwinding by DHX36 and FANCJ. Subsequent nucleolytic incision followed by renewal of the RNA-containing strand drive G-loop disassembly (2/4)

Inhibition of this mechanism causes global G4 and R-loop accumulation, leading to transcription dysregulation, replication stress, and genome instability. Thanks to cells from @joost84.bsky.social from the Tijsterman lab and amazing scEdUseq by @jervdberg.bsky.social from the Oudenaarden lab (3/4)

Congrats to Koichi Sato and @puckknipscheer.bsky.social on this beautiful paper! The biochemistry is 🤯 Happy to help with scEdUseq to pinpoint the DNA replication defects! 🎉🧬 RNA transcripts regulate G-quadruplex landscapes through G-loop formation | Science www.science.org/doi/10.1126/...
