Lipid peroxides articles from across Nature Portfolio

Cholesterol inhibits ferroptosis via CoQ10 and squalene metabolism and cholesterol diet can protect from hepatotoxicity.

Radiation colitis is a major side effect for pelvic radiotherapy patients, but there are limited available treatments. Here, the authors use a halloysite clay based material for the alleviation of radiation colitis in mice by inhibiting ferroptosis.

Old Masters used paints containing mixtures of oils and proteins, but we lack an understanding on how and why proteins were used. Here, the authors use egg yolk in combination with two pigments to evaluate how different repartition of proteinaceous binder can be used to control the flow behaviour as well as drying kinetics and chemistry of oil paints.

Lipid peroxidation plays an important role in cell signaling and disease as well as therapy, however, the effect on the membrane structure and mechanical behavior remains poorly understood. Here, the authors report the direct and quantitative measurement of the bilayer’s structure and viscoelastic properties upon peroxidation of lipid membranes.

The cyst(e)ine/glutathione (GSH)/glutathione peroxidase 4 (GPX4) axis is the most frequently targeted pathway to trigger the ferroptosis cascade and suppress tumor growth. Two recent studies present additional mechanisms underlying cystine starvation-induced ferroptosis apart from impaired GSH synthesis.

Ueli Schibler explains why the phenotype of a mutation in a codon of the ‘21st amino acid’ selenium cysteine was unexpectedly specific.
