This process is driven by disrupted GSH homeostasis, resulting from diminished GSH synthesis and impaired activity of two critical antioxidant systems: (1) the cystine/glutamate antiporter xCT, which imports cystine to fuel GSH production and (2) GPX4, which utilizes GSH to convert lipid peroxides into less toxic lipid alcohols (Stockwell et al., 2017
The mice were pretreated with dopamine antagonist haloperidol (5.0 mg/kg i.p.) and subsequently treated with amphetamine (20 mg/kg i.p.1, 2, 4 and 10 days after haloperidol pre-treatment), which is usually used for the study of behavioral supersensitivity to an amphetamine stimulating effect
The skincare industry has developed numerous vitamin C derivatives that remain stable at skin-friendly pH levels, work effectively without the same peptide-destroying acid load, and still deliver vitamin C benefits once absorbed into skin cells
