Amaranthus viridis-derived phytopriming reprograms redox homeostasis and limits arsenic accumulation in rice

This study shows that Amaranthus viridis extract reduces arsenic accumulation in rice by improving redox homeostasis and limiting arsenic uptake and translocation.

Reverse DTNB assay: a novel in vitrobiochemical approach to detect oxidized thiol modifications

The paper introduces a reverse DTNB assay to qualitatively and quantitatively analyze redox-modified thiol residues in proteins, offering a simpler alternative to existing methods.

Assessing the physiological S nitrosoproteome reveals nitric oxide mediated regulatory networks in rice

This study identifies the first in vivo S-nitrosoproteome in rice, revealing nitric oxide-mediated regulatory networks and potential physiological roles of S-nitrosylation.

Age-Associated Insolubility of Parkin in Human Midbrain is Linked to Redox Balance and Sequestration of Reactive Dopamine Metabolites

This study investigates how parkin's redox state and insolubility in human midbrain relate to oxidative stress and dopamine metabolism, showing that parkin's cysteine modifications affect H2O2 levels and neuroprotection.

Parkinson Disease-Linked Parkin Mediates Redox Reactions That Lower Oxidative Stress In Mammalian Brain

This study shows that parkin reduces oxidative stress in mammalian brains by mediating H2O2 reduction and glutathione regeneration, but its absence leads to increased oxidative stress despite compensatory mechanisms.

Oxidative Modifications of Parkin Underlie its Selective Neuroprotection in Adult Human Brain

This study identifies oxidative modifications of parkin in adult human brain that confer neuroprotection by reducing H2O2, conjugating dopamine radicals, and forming neuromelanin.
