Multiple cryo-electron microscopy structures of a plant ABC transporter exporting glutathione derivatives captured a closed conformation proposed to enforce the export directionality, while a complex central to the coupling mechanism containing both glutathione and closed nucleotide binding domains remains elusive.
Adapting a cytosolic enzyme that breaks down glutathione to function in the lumen of the endoplasmic reticulum challenges the long-held view that reduced glutathione fuels disulfide rearrangements during protein folding.

ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

The capacity to sustain effort to obtain rewards over time depends on the levels of the antioxidant glutathione in the nucleus accumbens - a brain region critical for motivated behavior - and can be boosted with a nutritional intervention (N-acetylcysteine).
As worms age reduced glutathione together with increased ferrous iron increases frailty and leads to ferroptosis, which is amenable to therapeutic intervention.
Cystathionine-β-synthase is a novel metabolic regulator of AKT-induced senescence and a potential tumor suppressor in gastric cancer pathogenesis which can be harnessed to target PI3K/AKT-driven cancers.
Combination of glutaminase inhibitor CB-839 and ASCT2 inhibitor V-9302 showed efficient antitumor effect against glutamine addicted liver cancer cells via glutathione depletion and reactive oxygen species (ROS) induction.
Breast cancer resistant to either doxorubicin or epirubicin relies on distinct primary metabolic processes, which can be targeted to reduce cancer progression.
