Very pleased to say that the paper version of our study examining the role of de novo DNMTs in cancer-associated hypomethylation is now out in @plos.org Genetics 🎉: doi.org/10.1371/jour... You can read more on the previous thread but here is a summary of the main updates! #epigenetics 🧵 1/9
New pre-print alert 🚨 Interested in what @ikafetzo.bsky.social learned about DNA hypomethylation in cancer from investigating surprising gains DNA methylation in DNMT1 KO cells? Read all about it here: www.biorxiv.org/content/10.1... For a quick summary see this 🧵 1/8 #epigenetics

Super excited to be launching two things today: #RustQC 🦀🧬 and rewrites.bio 🚀 I used AI to rewrite 15 RNA-seq QC tools into a single Rust binary (I've never written any Rust). It ended up being over 60x faster. Here's the story 🧵 seqeralabs.github.io/RustQC/
Welcome to RustQC
Fast quality control tools for sequencing data, written in Rust.

Antibodies don't work. NLRP3 is by far the most studied inflammasome — yet <30% of commercial antibodies were specific. Only 4 of 14 tested antibodies detected NLRP3 specifically. Antibodies must be validated before use. Full report by @ycharos.bsky.social : zenodo.org/records/1162...
If you work in AI for Science, take a moment to familiarize yourself with a common failure mode: paranormal citations (or paracites). Our paper describes them.
AI hallucinations in science manuscripts are a nuisance. Paranormal citations, or paracites, will be a nightmare. www.biorxiv.org/content/10.6... (w/ @sina.bio & @lauraluebbert.com).
We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n

Very excited that our paper describing a critical role for the PNUTS-PP1 phosphatase complex in transcription pause release is up online! This was a massive team effort with @edimitrova.bsky.social and the rest of the @robklose.bsky.social lab www.cell.com/molecular-ce... A short thread: (1/8)
The PNUTS phosphatase complex controls transcription pause release
Kelley et al. discover that the PNUTS phosphatase complex plays an essential role in gene transcription by controlling RNA polymerase II pause release. PNUTS achieves this through its TND, which recog...
