Tumor reliance on antioxidant defenses creates a vulnerability to ferroptosis, yet strategies to therapeutically disable these systems remain limit...

Iron abundance alone does not determine ferroptosis sensitivity. In this issue of Cell, Sharma and colleagues identify polyamines as endogenous metabolic buffers that reduce the chemical accessibility...

A California bill would give voters the chance to vote on whether the state should create a $23 billion bond that would be used to award grants to university researchers.

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...

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...

Nature Structural & Molecular Biology, Published online: 13 March 2026; doi:10.1038/s41594-026-01760-4The oxidoreductase FSP1 recycles radical-trapping antioxidants that suppress oxidative lipid damage and ferroptosis. A series of genetic screens reveal a key role for the vitamin B2 metabolite flavin adenine dinucleotide in stabilizing FSP1, preventing its proteasomal degradation and promoting ferroptosis suppression.

CRISPR–Cas9 screening identifies CLCC1 as a factor that increases neutral lipid flux to prevent hepatic steatosis and promotes nuclear pore complex assembly by promoting membrane bending and fusi...

Deletion of Aifm2 disrupts Treg cell immunosuppression within tumors without inciting autoimmune pathology in mice.

Imbalances in lipid storage and secretion lead to the accumulation of hepatocyte lipid droplets (LDs) (i.e., hepatic steatosis). Our understanding of the mechanisms that govern the channeling of hepat...

Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.

A DNA nanoruler platform enables precise measurement of the labeling radii of TurboID and APEX2, uncovering their contact-dependent mechanisms. These findings redefine the enzymology of proximity labe...

FSP1 is a key suppressor of lipid peroxidation and ferroptosis, yet it is largely dispensable in standard cell culture models. Two new studies now show that FSP1 becomes essential for tumour growth in...

Heterobifunctional proteolysis-targeting chimeras (PROTACs) have emerged as a powerful strategy to degrade disease-relevant proteins, enabling targeting of previously "undruggable" proteins. Current d...

The Taipale lab in the Donnelly CCBR and University of Toronto is looking for a highly motivated Postdoctoral Fellow

Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.

Lipid droplets (LDs) originate from the endoplasmic reticulum (ER) and are unique among cellular organelles, as they consist of a hydrophobic core of neutral lipids that is surrounded by a phospholipi...
