Vitamin B2 metabolism promotes FSP1 stability to prevent ferroptosis - Nature Structural & Molecular Biology Here, Deol et al. use genetic screens in gene-edited reporter cell lines to identify regulators of ferroptosis suppressor protein 1 (FSP1) expression and stability. They show that vitamin B2 metabolis...

1/3 Thrilled to see our paper led by Kirandeep Deol is out in Nature Structural & Molecular Biology! CRISPR screens to uncover a role for vitamin B2 metabolism in stabilizing FSP1 via FAD, revealing a new way vitamins regulate ferroptosis.

Riboflavin metabolism shapes FSP1-driven ferroptosis resistance - Nature Cell Biology After performing a focused CRISPR–Cas9 screen, Skafar et al. identify riboflavin (vitamin B2) as a regulator of FSP1 stability that modulates phospholipid peroxidation and ferroptosis sensitivity in c...

Happy to share the final version of the study where we describe a central role for vitaminB2 in regulating membrane redox state - some new cool experiments were added since the preprint was posted - pls check this out

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.

🧪🧬 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.
