SOD1 and ischemic stroke: For instance, electroacupuncture (EA) at GV20 (Baihui) and GV24 (Shenting) has been shown to enhance cerebral blood flow and mitigate oxidative damage in ischemic stroke models, likely through upregulation of antioxidant enzymes (e.g., SOD, CAT) and suppression of lipid peroxidation.
