24-Epibrassinolide, a Phytosterol from the Brassinosteroid Family, Protects Dopaminergic Cells against MPP⁺-Induced Oxidative Stress and Apoptosis

Figure 1

Experimental design to examine the effect of 24-Epi on MPP⁺-induced cellular death and oxidative stress. Cells were pretreated with 24-Epi (10⁻⁹ M) or vehicle 3 h before MPP⁺ administration. Neuronal cells were harvested at the indicated time periods after each experimental methodology described in Section 2.
