Terrible figure. FerrOztosis is a great ferroptosis conference in Melbourne though.

HMOX1 controls a heme/ferritin switch that protects cells from ferroptosis Modulating the intracellular labile iron pool (LIP) has emerged as a promising strategy to induce ferroptosis in cancer cells, offering a way to overcome resistance to apoptosis-based therapies. One o...

Heme and iron toxicity in the aged spleen impairs T cell immunity through iron deprivation - Nature Aging In their study, Ezuz et al. show that the aged spleen contributes to T cell aging through hemolytic stress and an increasingly heme- and iron-rich microenvironment. T cells adapt by limiting their iro...

Coenzyme Q headgroup intermediates can ameliorate a mitochondrial encephalopathy

Wow

Fascinating idea!

FYI - We've extended abstract submission deadline to June 8. Submit soon to be considered for a short talk. Come join us at the first FASEB #Ferroptosis meeting! It's going to be awwwwesome! 🤩

Cocrystal structure reveals the mechanism of FSP1 inhibition by FSEN1 | PNAS FSP1 is an FAD-dependent oxidoreductase that uses NAD(P)H to regenerate the reduced forms of lipophilic quinone antioxidants, such as coenzyme Q10 ...

Thrilled this paper is out! We solved the first cocrystal structure of FSP1 with an inhibitor (FSEN1), providing mechanistic insight & a foundation for medchem. Led by Amalia Megarioti & Sitao Zhang. A terrific collaboration with Da Jia.

Lipid-degrading small molecule kills cancer cells by ferroptosis A molecule designed to activate iron locked up in organelles called lysosomes and thereby induce cell death might offer a way to tackle treatment-resistant cancer.

Excited to see our N&V w/ @mikelangelipid.bsky.social published in Nature, highlighting new work from Raphael Rodriguez and team. A heterofunctional molecule that activates lysosomal iron triggers lipid peroxidation and ferroptosis in therapy-resistant cancer cells. www.nature.com/articles/d41...

Activation of lysosomal iron triggers ferroptosis in cancer - Nature Some cancer cells exhibit high loads of reactive iron in lysosomes, and this feature is exploited by using fentomycin-1, a newly developed small molecule, to induce ferroptosis.

Here is our latest paper in @ACSBiol on compounds that restore activity to the R152H GPX4 variant, found in patients with SSMD. Congrats to Hengrui, Farhad and Russ on a great collaboration! @columbia #ferroptosis pubs.acs.org/doi/full/10....

Our team (hsph.harvard.edu/research/ube...) is excited to have contributed to the intranodal in vivo testing of the remarkable new compound, Fentomycin-1. Congrats to team Rodriguez et al. for the implications of this work in targeting ferroptosis in cancer. Check it out here!

N-acetyl-l-cysteine averts ferroptosis by fostering glutathione peroxidase 4 Zheng and Zhang et al. identify N-acetyl-l-cysteine (NAC) and its enantiomer N-acetyl-d-cysteine (d-NAC) as direct reducing substrates of glutathione peroxidase 4 (GPX4). They further reveal a broad r...

Interesting study that attempts to explain how NAC rescues from direct GPX4 covalent binding inhibitors. Was always a bit of a mystery and it looks to me like there might be more to it. www.cell.com/cell-chemica...
