Multiple oestradiol functions inhibit ferroptosis and acute kidney injury - Nature 17β-oestradiol establishes an anti-ferroptotic state in female kidney tubules.

Happy to start at Bluesky with a post on our recent manuscript at @nature.com:

www.nature.com/articles/s41...

Great collaboration with cool scientists such as @theprattgroup.bsky.social, @fedorovalab.bsky.social and many who do not (yet) have a Bluesky account.

Congrats! Looking forward to digging into this important review! 🤩

Hot off the presses! Was an honor to team up with Scott Dixon @stanforduniversity.bsky.social on this Nature Cancer review. We reflect on hurdles that have slowed translation of ferroptosis-directed therapies and share ideas on what it will take to bring these therapies to the clinic. rdcu.be/eBbqV

Jessalyn Ubellacker @ubellackerlab.bsky.social was honored with a FASEB Journal Early Career Researcher Award at the first FASEB Ferroptosis, Oxidative Stress, and Lipid Metabolism meeting, co-organized by James Olzmann @olzmannlab.bsky.social and Scott Dixon, to support early career researchers.

Jennifer Doudna named 2026 Priestley Medalist by the American Chemical Society.

Congrats to MCB's Jennifer Doudna @jenniferdoudna.bsky.social on receiving the 2026 ACS Priestley Medal from the @acs.org! 👏🏅

Lysosomal membrane homeostasis and its importance in physiology and disease Nature Reviews Molecular Cell Biology, Published online: 04 August 2025; doi:10.1038/s41580-025-00873-wLysosomes degrade cellular components, and their membrane is an important signalling hub. Recent insights into the mechanisms that maintain lysosomal membrane homeostasis — including the interplay between membrane damage, repair, lysophagy and lysosome biogenesis — highlight their importance in physiology, in disease and during ageing.

Protein language models reveal evolutionary constraints on synonymous codon choice Evolution has shaped the genetic code, with subtle pressures leading to preferences for some synonymous codons over others. Codons are translated at different speeds by the ribosome, imposing constrai...

This preprint from Helen Sakharova is one of the coolest things to come out of my lab: “Protein language models reveal evolutionary constraints on synonymous codon choice.” Codon choice is a big puzzle in how information is encoded in genomes, and we have a new angle. www.biorxiv.org/content/10.1...

Riboflavin metabolism shapes FSP1-driven ferroptosis resistance https://www.biorxiv.org/content/10.1101/2025.08.05.668651v1

Vitamin B2 metabolism promotes FSP1 stability to prevent ferroptosis https://www.biorxiv.org/content/10.1101/2025.08.05.668752v1

Exciting work! Congrats, Pedro and Team! :D

Riboflavin metabolism shapes FSP1-driven ferroptosis resistance Membrane protection against oxidative insults is achieved by the concerted action of glutathione peroxidase 4 (GPX4) and endogenous lipophilic antioxidants such as ubiquinone and vitamin E. Deficienci...

🚨Preprint alert 🚨

We identify riboflavin (vitamin B₂) as a key modulator of ferroptosis sensitivity via stabilizing FSP1 & recycling lipid-soluble antioxidants.

Also see a new preprint from @angelifriedmann.bsky.social and colleagues that makes similar discoveries related to vitamin B2 / FSP1 stability and ferroptosis regulation: 👏🏽

Vitamin B2 metabolism promotes FSP1 stability to prevent ferroptosis Ferroptosis, a regulated form of cell death driven by excessive lipid peroxidation, has emerged as a promising therapeutic target in cancer. Ferroptosis suppressor protein 1 (FSP1) is a critical regul...

Excited to share our new preprint, led by Kirandeep Deol! 🤩 Genetic screens uncover mechanisms regulating FSP1 abundance in cancer. Vitamin B2 metabolism promotes FSP1 stability via FAD synth / binding, further linking nutrient metabolism to ferroptosis.
