Polydatin Attenuates OGD/R-Induced Neuronal Injury and Spinal Cord Ischemia/Reperfusion Injury by Protecting Mitochondrial Function via Nrf2/ARE Signaling Pathway

Figure 9

Mechanistic basis of the neuroprotective action of PD in SCII. PD promotes the nuclear translocation of Nrf2 and activates Nrf2/ARE singling, thereby inducing the ARE-driven genes NQO-1 and HO-1 that attenuate mitochondrial dysfunction. It also restores the Bcl-2/Bax balance and blocks Cyt-c-initiated Caspase cascade, which prevents neuronal damage and apoptosis.
