Selection of suitable concentration and time for 6-OHDA treatment of cells. The cell viability of SH-SY5Y cells treated with different concentrations (10, 50, 100, 150, and 200 μM) of 6-OHDA at 0, 3, 6, 12, 24, and 48 h was detected using MTT assay. Each experiment was repeated for three times independently. Data are presented as mean ± standard deviation. One-way ANOVA was employed for the comparisons among multiple groups and Dunnett’s multiple comparisons test was applied for the post hoc test, ∗∗p < 0.01 vs. control group at the same time point.
