Abstract

MPP$\^$+/ is known to be a neurotoxic substance that induces the degeneration of dopaminergic neurons and Parkinson-like syndrome. Incubation with MPP$\^$+/ induced the expression of heme oxygenase-l (HO-1) in PC-12 cells and HO-1 revealed a protective effect against MPP$\^$+/ -induced cytotoxicity. In this study. we tested the effect of pre-conditioning on the MPP$\^$+/-induced cytotoxicity. The PC-12 cells were incubated with MPP$\^$+/ for 3 hrs. and then after 12 hrs the cells were exposed to several concentration of MPP$\^$+/. (omitted)
