In 2014, Chen et al. found that bajijiasu, isolated from Morinda officinalis, alleviates Aβ-induced oxidative stress mainly through SOD, CAT, and GSH-Px activity upregulation and MDA activity downregulation in the hippocampus at 25 days after Aβ25–35-induced AD [23]. Here, SOD1 is linked to Alzheimer disease.
