Abstract To explore the protective impact of the ginger root ethanol extract (GRE) against the oxidative stress induced by 6-hydroxydopamine (6-OHDA) and apoptotic and its mechanism. Parkinson's disease (PD) model was established using 6-OHDA in the cells of rat adrenal pheochromocytoma (PC12). The GRE pretreatment increased PC12 cell viability of injury induced by 6-OHDA. The GRE effectively suppressed 6-OHDA-induced death, apoptosis through decreased Bax and cleaved-caspase 3 expression, and up-regulated expression of B-cell lymphoma 2 (Bcl-2). GRE also inhibited 6-OHDA-inducel oxidative stress, decreased reactive oxygen species (ROS) and up-regulates the heme oxygenase (HO-1), antioxidant enzymes, catalase and, glutathione (GSH), superoxide dismutase (SOD), 8-oxoguanine glycosylase1 (OGG1) and NAD(P)H quinone oxidoreductase1 (NQO1). Besides, GRE up-regulating Protein kinase B (Akt), nuclear erythroid 2-related factor 2 (Nrf2), down-regulating nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) translocation, together with the mitogen-activated protein kinase (MAPK) phosphorylation. In conclusions, the GRE prevented apoptosis and oxidative stress in 6-OHDA-induced PC12 cells. The ginger ethanol extract could be treatment and prevention of PD.
