Abstract

Berberine (BBR) is one of the major Alkaloids and has been reported to have a variety of pharmacologic effects, including inhibition of cell cycle progression. Here, we investigated the mechanisms of BBR protection of neuronal cells from cell death induced by the Parkinson's disease-related neurotoxin 6-hydroxydopamine (6-OHDA). Pretreatment of SH-SY5Y cells with BBR significantly reduced 6-OHDAinduced generation of Reactive Oxygen Species (ROS), Caspase-3 activation, and subsequent cell death. BBR also upregulated heme oxygenase-1 (HO-1) expression, which conferred protection against 6-OHDA-induced dopaminergic neuron injury and besides, effect of BBR on HO-1 was reversed by siRNA-Nrf2. Furthermore, BBR induced PI3K/Akt and p38 activation, which are involved in the induction of Nrf2 expression and neuroprotection. These results suggest that BBR may be useful as a therapeutic agent for the treatment of dopaminergic neuronal diseases.
