📣📣It is great to finally welcome @cnicproteomics.bsky.social to Bluesky 🎊 Follow them if you want to learn about the latest development in PTM research applied to cardiovascular diseases! 🫀🧪🧫🖥️🛠️

Today at CNIC we had the pleasure to host @clairekoenig.bsky.social for her talk about "Proteins for the past". It sparked a lot of interest!

El pasado viernes, 6 de junio, realizamos por primera vez el workshop "Enseña tu técnica", en el cual participaron cinco jóvenes investigadores, deleitándonos con interesantes e innovadoras técnicas que llevan a cabo en su trabajo diario.

No perdáis la oportunidad de registraros en la 1ª edición de “Enseña tú técnica”, en la cual, jóvenes investigadores con gran motivación, nos ilustrarán con diversidad de herramientas en las que están especializados. ¡Os esperamos!

📣 Thrilled to announce that my latest work during my postdoc at @jesperolsenlab.bsky.social is finally published!
Check out our quantitative proteomics analysis on a premetastatic colorectal cancer cohort, and how we identify potential biomarkers to assess risk relapse.

Protein aggregation capture assisted profiling of the thiol redox proteome Oxidative damage is critical in various diseases, including cardiovascular and neurological conditions. Thiol redox reactions, acting as oxidative stress sensors, influence protein structure and function. Redox proteomics based on differential alkylation of reduced and oxidized Cys forms using mass spectrometry enables comprehensive analysis of thiol redox status in cells and tissues. We introduce PACREDOX, an innovative redox proteomics approach based on the Protein Aggregation Capture (PAC) protocol and we demonstrate its compatibility with library free data-independent acquisition (DIA). PACREDOX reduces preparation time and costs compared to traditional methods, such as FASILOX, while maintaining thiol and proteome coverage. To enable library-free DIA, we corrected in silico spectral libraries in DIA-NN using experimental retention time data from beta-methylthiol-modified peptides. PACREDOX with DIA quantified 4,000 protein groups and ~45,000 modified peptides in myocardial tissue from a porcine model of atrial fibrillation, including over 8,000 cysteine-containing peptides, 30% of which were reversibly oxidized. Benchmarking PACREDOX and DIA against FASILOX in a myocardial infarction model reflects the potential and efficiency of this methodology to study oxidative damage. Overall, PACREDOX offers a high-throughput, cost-effective strategy for thiol redox proteome analysis, compatible with label-free quantitative workflows. ### Competing Interest Statement The authors have declared no competing interest.

📣📣First post for many things: 1st one in bluesky and 1st one of my work since joining CNIC!
Preprint for our novel implementation of PAC and DIA for REDOX proteomics, with application to cardiovascular diseases♥️🐖🔬. Check it out in @biorxivpreprint.bsky.social

Yes, please, that one also seems an amazing group!

@clairekoenig.bsky.social and myself just joined, it would be great to join the pack as well 🐺
