Cells may work with “Lego®️ bricks” 🧱 at the molecular level. Our new study shows that peroxiredoxins can mix different subunits to form hybrid complexes arranged in donut-like rings 🍩, creating molecular diversity that helps cells fine-tune stress and redox signaling responses. Out in Nat Chem Biol.

Congratulations Julia! 🙌🏻 🥳

As scientists, it is our duty to inform, educate and properly communicate with the public. If you want to learn how to do it from a reference in the field @andresrieznik.bsky.social , do not miss the next SFRR-E Science Outreach webinar. 📢

🧪🧬 New preprint!
What if the same biosensor could reveal how cysteine is regulated across life domains?

We introduce Cystector, a genetically encoded fluorescent biosensor for real-time cysteine monitoring in living cells.

Cancer Metabolism: Historical Landmarks, New Concepts, and Opportunities - PubMed Cancer cells undergo changes in metabolism that distinguish them from non-malignant tissue. These may provide a growth advantage by promoting oncogenic signaling and redirecting intermediates to anabolic pathways that provide building blocks for new cellular components. Cancer metabolism is far from …
