Thread: Multi-omics sounds cool—until you actually try it. Here's are the nuances.
1/
You’ve got RNA-seq.
Methylation.
Proteomics.
Time to “integrate” the data.
But how? And why?
Let’s break it down.

Unexpectedly, @jurgjn.bsky.social found that running Alphafold3 predictions for protein interactions can yield ipTM scores that are more predictive of true interactions when run in pools of proteins instead of pairwise predictions. Presumably, this reflects some sort of "competition effect".

New preprint: We isolate peptide–RNA photo-crosslinks with tunable RNA chains from living cells for mass spec. This maps over 4,700 crosslinking sites across 744 proteins and offers the first glimpse into the RNA sequences in crosslinks by MS. Read here: doi.org/10.1101/2025...

Our new review paper about Pathway-Centric PTM Data Analysis is out this week in #Proteomics!
We cover databases, enrichment tools, software for pathway reconstruction, and full-fledged platforms that help to interpret high-throughput PTM datasets.
Check it out here: doi.org/10.1002/pmic...
Computational Approaches for Pathway‐Centric Analysis of Protein Post‐Translational Modifications
Protein function is dynamically modulated by post-translational modifications (PTMs). Many different types of PTMs can nowadays be identified and quantified at a large scale using mass spectrometry. ...

A really nice example on how to visually communicate the text contents of a paper on mobile phones
A must-read, must-share piece - clearly deconstructing the shoddy science of the Geiers (who are inexplicably in charge of studies at HHS).

Consider this an early warning for what lies ahead. 🛟🩺🧪

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes.

This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

Bioinformatics isn't just code.
It's skepticism.
It’s pattern recognition.
It’s noticing when something feels off.
Your instincts matter.
Listen to them.
Then verify with data.

If there any #Sciex decision makers here on Bluesky - I urge you to reconsider. Skyline/Proteowizard support is not only important for your customers using these tools, but it also benefits other bioinformatics efforts that depend on these tools.
Disappointing to see, across both parties.
Sciex is no longer providing funding for Skyline/Proteowizard as part of the multi-vendor agreement to keep Skyline supported across all major vendors.
I can see the arguments from both sides, just a shame it's resulted in this.
