GPX1 and Stroke: We observed that, two weeks post-stroke, rehabilitation with ELF-EMF exposition caused an increase in antioxidant enzymes activity: CAT and superoxide dismutase (SOD) [24], as well as elevation of the expression of antioxidant enzymes genes: CAT, SOD (SOD1 and SOD2), and glutathione peroxidase (GPx1 and GPx4) [21].
