PMID: 39983344
The physiological functions of supersulfides, inorganic and organic sulfides with sulfur catenation, have been extensively studied. Their synthesis is mainly mediated by mitochondrial cysteinyl-tRNA synthetase (CARS2) that functions as a...

PMID: 38867112
Ferroptosis is a form of regulated cell death induced by iron-dependent accumulation of lipid hydroperoxides. Selenoprotein glutathione peroxidase 4 (GPX4) suppresses ferroptosis by detoxifying lipid hydroperoxides via a catalytic selenocysteine...

PMID: 38336829
Currently available genetically encoded HO probes report on the thiol redox state of the probe, which means that they reflect the balance between probe thiol oxidation and reduction. Here we...
