Metabolites are not genes — avoiding the misuse of pathway analysis in metabolomics
Nature Metabolism, Published online: 10 April 2025; doi:10.1038/s42255-025-01283-0Pathway analysis, originally developed for gene expression data, has been adapted for metabolomics. However, owing to the unique characteristics and constraints of metabolites compared with genes, pathway analysis in metabolomics often yields misleading or nonsensical results.

What happens when sequencing costs go ⏬ ? Imagination and new opportunities go ⏫ @landau.bsky.social Let's look at what you can do when you perform deep WGS on cfDNA for cancer detection. Our recent work with the @UltimaGenomics platform 🧵👇 Lets goooo!! rdcu.be/ehkUb

"Your AI can’t see gorillas!" A few years ago we found that students are more likely to see the gorilla in their data if they are not also asked to test a specific hypothesis. In his blog Chiraag Gohel now shows that Chat-GPT can’t help you to find it either. chiraaggohel.com/posts/llms-e...

"Imagine a DAPI-like stain, but for the extracellular matrix." That's basically how this work was pitched to me by Kayvon and Antonio a year or so ago. Now the final product really delivers. Read about their versatile label for ECM in living tissues here: www.nature.com/articles/s41...

Delighted to share our latest paper describing a method to read the levels of hundreds of metabolites or drugs in parallel using DNA sequencing. This method, which we call ‘smol-seq’ (Small MOLecule sequencing), harnesses the power of DNA sequencing for metabolite detection: rdcu.be/d8xLv (1/6)

#NoTimeToDie! @inflammasomelab, Holley, Monteleone &co show @natimmunol.bsky.social that cells that die by #pyroptosis, or #necroptosis, are crowned with F-actin filopodia that makes them visible by dendritic cells via CLEC9A to initiate adaptive immunity! www.nature.com/articles/s41...

Pyroptotic cell corpses are crowned with F-actin-rich filopodia that engage CLEC9A signaling in incoming dendritic cells - Nature Immunology
Pyroptotic cell death results in inflammation. Here the authors find that F-actin-rich structures formed during macrophage pyroptosis persist after cell death to activate dendritic cells.

One of the alluring and theoretical strategies for extending healthspan and longevity is to rejuvenate the thymus gland, promote an intact immune system. Now there's a way to do that in aged mice. www.science.org/doi/10.1126/...

We ask students to write a research proposal, but we should also teach them about how the project will likely actually unfold.
