“…Since 2001 a number of other laboratories have provided additional key insights into the oxytosis pathway, including those of Axel Methner (Albrecht et al, 2010), Marcus Conrad (Seiler et al, 2008), Carsten Culmsee (Dolga et al, 2018), and Rajiv Ratan (Ratan, 2020), as will be described below.…”

“…[ 6 ] Glutamate can reduce cystine input by inhibiting the cysteine/glutamate transport system, leading to intracellular glutathione (GSH) depletion and decreased GPX4 activity, which in turn leads to cell death due to excessive oxidative stress. [ 7 ] It is always used as an aging model inducer. In this study, glutamate treatment was also used to construct a cellular model of aging to explore the resistance of DHMBA to aging caused by glutamate.…”

Scope3,5‐Dihydroxy‐4‐methoxybenzyl alcohol (DHMBA) is found in oyster extracts in recent years and is reported to have antioxidant activity. Although it has been reported to be protective in various models of oxidative stress, the therapeutic effect of DHMBA on neurological damage caused by aging remains to be demonstrated.Methods and ResultsThe present study investigates the potential functions of DHMBA in brain of old C57BL/6J mice and aging cell model. Administration of DHMBA improves working memory, reduces anxiety behavior, decreases the expression levels of cell cycle proteins, cycin‐dependent kinase inhibitor 1(P21) and peptidase inhibitor 16(P16) and inhibits neuronal loss in old mice. The data obtained from the aging cell model are consistent with those from the old mice. The interaction between DHMBA and Kelch‐like ECH‐associated protein 1 (Keap1) is predicted by molecular docking assay, and then it is verified by co‐immunopricipitation (CoIP) that factor red lineage 2‐related factor 2 (Nrf2)‐Keap1 protein‐protein interaction is inhibited by DHMBA. Protein levels of Nrf2 and its target genes, such as glutathione peroxidase 4(GPX4) and heme oxygenase 1 (HO‐1), are detected in old mice and aging cell model.ConclusionThis study provides new evidence that explores the antioxidant mechanism of DHMBA and implies a potential role of DHMBA on antiaging in brain.
