ALA attenuates 6-OHDA-induced increase in ROS levels of PC12 cells. (A) Corresponding DCF-fluorescent picture induced by 200 μM 6-OHDA and/or 10 μM ALA in PC12 cells. The brightened dot represents the fluorescence of ROS. (B) DCF fluorescence intensity induced by 200 μM 6-OHDA and/or 10 μM ALA in PC12 cells. Data were expressed as the means ± SD analyzed by one-way ANOVA (n = 3). Statistical significance: *P < 0.01 vs. control; #P < 0.01 vs. 6-OHDA group.
