| Abstract:
The endogenous neurotoxin 5-S-cysteinyl-dopamine (CysDA) has been linked to the degeneration of dopaminergic neurons in the Substantia nigra. Sulforaphane (SFN) is an isothiocyanate derived from cruciferous vegetables that has been proposed as a potential chemopreventive agent, although its effects on other cells are less clear. This study was undertaken to investigate the protective effects of SFN against CysDA-induced injury in primary cortical neurons. The results indicate that SFN protects primary cortical neurons against CysDA-induced injury by a mechanism involving the increased nuclear translocation of Nrf2 and the increased activity of phase II enzymes such as glutathione-S-transferase, glutathione reductase, and thioredoxine reductase. Moreover, the protection exerted by SFN appears to be mediated by the activation of the extracellular signal-regulated kinase 1 and 2 (ERK1/2) and Akt/protein kinase B (PKB) pathways. | |
