Citation abstract

Rotenone is a pesticide that has been shown to induce the pathological symptoms of Parkinson's disease (PD) in both cellular and animal models. In this study, we investigated the protective effect of Agaricus blazei extract on rotenone-induced dopaminergic degeneration and apoptosis in mice model. A. blazei extract blocked the rotenone-mediated diminution of dopamine transporter (DAT) and vesicular monoamine transporter 2 (VMAT 2) expression and the downregulation of Bcl-2 and the upregulation of Bax, caspases-3, -6, -8 and caspase-9. Present data suggest that A. blazei extract plays a crucial role in regulation of proteins expression such as DAT and VMAT2 and pro-apoptotic and anti-apoptotic in Parkinsonism. In conclusion, the present study shows that A. blazei extract act as potential neuroprotective agent in the management of Parkinsonism.
