In a rat model of cerebral ischemia, Pei et al. (56) demonstrated that exogenous injection of BMP7 effectively mitigated neuronal death induced by ischemia, improved glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD) activities, and mitigated neuronal death caused by ischemia, ultimately improving oxidative stress-induced brain damage. Here, SOD1 is linked to ischemia.
