🚨Preprint alert 🚨 We identify riboflavin (vitamin B₂) as a key modulator of ferroptosis sensitivity via stabilizing FSP1 & recycling lipid-soluble antioxidants. www.biorxiv.org/content/10.1.... pls check @olzmannlab.bsky.social www.biorxiv.org/content/10.1... #ferroptosis #FSP1 #antioxidants

Happy to finally share my last contribution of my PhD work on protein carbonylation. These diverse and low abundant non-enzymatic PTMs have strong implications in protein structure. Here we show how we managed to consistently detect them in serum of 68 individuals. pubs.acs.org/doi/10.1021/...

Happy to share our latest #Lipidomics results: Together with Patricia Prabutzki & @fedorovalab.bsky.social we looked at lipidome remodeling along development of fibro-calcific aortic valve disease. Turns out, it is quite different in male & female patients! tinyurl.com/2bpujp8p

Please repost: Deadline extended until May 1st - join us for discussing cutting-edge cardiometabolic basic and translational research! Outstanding speaker lineup, highly interactive program, ca. 35 short talks selected from abstracts, and the most beautiful venue at Lake Starnberg: eas-elc.org

Important walkthrough for newcomers in the field rdcu.be/eg58p

We will be hosting the first @mzmine.bsky.social Community Meeting at @iocbprague.bsky.social. Please register if you wish to learn about the latest developments in mzmine. More info: docs.google.com/document/d/1...

Job alert 🧪 ‼️ Hi #teammassspec: In our #RTG2467 @unihalle.bsky.social we have a job opening for a PhD student in my group! 🎉 If you want to do cool stuff in cross-linking mass spectrometry of the tumor suppressor p53, please take a look: personal.verwaltung.uni-halle.de/jobs/wissmi/ Please RT!

Exciting times indeed! With so many new tools entering the field, we can hope to find the answers to many questions in lipid cell biology! Was happy to contribute to this viewpoint.

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that. www.biorxiv.org/content/10.1...

Ever wondered how #mitochondria fragmentation comes about during #ferroptosis ? Read our new paper on Drp1-mediated promotion of ferroptotic #celldeath. Great @cecad.bsky.social collaboration with Ana Garcia Saez! rdcu.be/d7L66

I am excited to report the preprint of my postdoc work in the @olzmannlab.bsky.social! We have discovered the first lipid droplet quality control pathway with broad implications for lipid physiology and diseases associated with LD accumulation and oxidative stress! #lipidtime shorturl.at/2HqFd

FSP1-mediated lipid droplet quality control prevents neutral lipid peroxidation and ferroptosis https://www.biorxiv.org/content/10.1101/2025.01.06.631537v1
