摘要
Oxidative stress contributes to neuronal death in the brain, and neuronal death can cause aging or neurodegenerative disease. Heme oxygenase 1 (HO-1) serves a vital role in the regulation of biological reactions, including oxidative stress associated with reactive oxygen species. In the present study, acerogenin C isolated from the Aceraceae plant Acer nikoense, which is used as a Japanese folk medicine for hepatic disorders and eye diseases. However, there have been no studies on the mechanisms underlying the antineurodegenerative biological activities of acerogenin C. In the present study, acerogenin C demonstrated neuroprotective action against glutamate-induced cell death in hippocampal HT22 cells through the upregulation of HO-1 expression. These effects were also associated with nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and the activation of phosphoinositide 3-kinase/protein kinase B. Taken together of the efficacy researches, this study determines that the Nrf2/HO-1 pathways denotes a biological mark and that acerogenin C might contribute to prevention of neurodegenerative disorders.
