Calycosin-7-O-β-D-glucoside modulates copper homeostasis through SLC31A1 to mitigate cuproptosis in cerebral ischemia/reperfusion injury.

Cuproptosis is a type of copper-dependent cell death, yet whether it participates in neuronal death during cerebral ischemia/reperfusion injury (CI/RI) has not been thoroughly investigated. As one of the characteristic components of Astragali radix, calycosin-7-O-β-D-glucoside (CG) exhibits potential pharmacological benefits on CI/RI, but its specific regulatory mechanisms are still insufficiently understood. This study was intended to illustrate the incidence of cuproptosis in CI/RI and to explore the mechanism of CG in mitigating CI/RI.

Puerarin mitigates cerebral ischemia/reperfusion (CIR)-induced ferroptosis by suppressing Ser15 phosphorylation-mediated p53 activation.

Cerebral ischemic stroke is a primary contributor to global mortality and disability, with its prevalence rising alongside aging population. While the restoration of blood supply to the ischemic brain regions is crucial, the subsequent cerebral ischemia/reperfusion (CIR) injury can trigger a cascade of pathological events associated with cell death. Ferroptosis, a form of regulated cell death characterized by iron-dependent lipid peroxidation, plays a significant role in the pathophysiology of CIR injury and has emerged as a key target for improving the unfavorable prognosis following ischemic stroke.

Catalpol Research on the Mechanism of Antimyocardial Reperfusion Injury by Regulating the MiR-126/TWEAK-FN14 Pathway: In Vitro and Computer Simulation Studies.

The objective of this study was to investigate the mechanism through which catalpol (CAT) exerts its protective effects in the context of myocardial ischemia-reperfusion injury.
