⚠️ Paper alert: Using a novel CRISPR screening approach, we mapped the entire regulatory network controlling Xist—key for X-chromosome inactivation.

Thanks Joe.

Thrilled to share our new Brockdorff lab paper at NSMB: we show that the primary role of m6A RNA modification on Xist is to promote RNA degradation. Xist turnover is mediated by the NEXT complex, not PAXT, and is independent of the m6A reader YTHDC1. www.nature.com/articles/s41...

Today, I would like to honor the memory of Roger Y. Tsien, who died on August 24, 2016. His legacy lives with all who use his technologies, including calcium sensors, fluorescent proteins, the acetoxymethyl (AM) ester, & many more! #FluorescenceFriday

New method drop:
HCR-Proxy, a modular proximity labelling approach to profile local proteome composition around RNA at nanoscale, subcompartmental resolution. Thereby we resolved nested nucleolar layers and uncovered the grammar of spatial protein partitioning.

Check out the latest study from our lab, led by Coffee Xiang (@coffeebond007.bsky.social) www.nature.com/articles/s41... (1/2)

Very happy to share our protocols paper for CELLO-seq. This will make single cell long read RNA-seq more accessible and provides analysis guidelines. We hope this helps the #transposon #TEsky community and folks working on #singleCell isoform and allelic #gene expression. doi.org/10.1038/s415...

Fresh preprint by @flavia-con.bsky.social from our lab uncovers how SMCHD1 finds & binds chromatin using live-cell single-molecule imaging🔬

She reveals how SMCHD1 dynamically engages chromatin, including the inactive X chromosome, to maintain gene silencing.

Excited to share our new paper on Nature - how Ku accommodates Alu expansion in primates by binding to dsRNA, providing a clue for both the high levels of Ku and its essentiality in human cells. Thank @chaolinzhang @hchung03 @LenaSteckelberg More to come www.nature.com/articles/s41...

An emotional day today @oxfordbiochemistry.bsky.social where leaders in the cell cycle field gathered to celebrate the life of Bela Novak and the huge impact he had on their work! www.bioch.ox.ac.uk/article/prof...

I can’t believe this. He is so kind and friendly.

Prime editing is precise and flexible, but it can require a lot of optimization. This post will give you some tips to get started making your prime edit as effective as possible!

I am thrilled to share our latest work, released today 🤩

www-nature-com.insb.bib.cnrs.fr/articles/s41...

It results from years of hard work by the team and long-time collaborators, with special thanks to PhD student Clara Roidor and collaborator Laurène Syx.

Preprint alert. Excited to share our latest work. We demonstrate that the primary function of m6A on Xist is to promote RNA degradation. www.biorxiv.org/content/10.1...

Here it is! Congratuations to @jesskelley.bsky.social @edimitrova.bsky.social @neilblackledge.bsky.social @aleksszczurek.bsky.social and the rest of the team (Maciej, Amy, and Hieu). This was a fab collaboration with Arminja Kettenbach. Also see a lovely complementary paper from Fei Chen's group.

Great thread on our paper from Jan👇

(1st post @BlueSky) Preprint alert🚨a long thread. Cautions in the use of @nanopore sequencing to map DNA modifications: officially reported “accuracy” ≠ reliable mapping in real applications. We performed a critical assessment of nanopore sequencing (across different versions of models) for the 1/n

I've been meaning to write a lengthy thread about our experiences with DNA methylation editing in mouse ESCs if that would be useful (or interesting?) for a niche audience here. tl;dr: it was frustrating but we learned a lot, and it ended with our shiny new pub (1/17) www.nature.com/articles/s41...
