FA reduces the ROS levels in 6-OHDA- or H₂O₂-treated PC-12 cells. (a, b) PC-12 cells were treated with FA or NAC in the absence or presence of 6-OHDA (a) or H₂O₂ (b) at the indicated concentrations for 24 h. After treatment, the cells were incubated with an H₂DCFDA probe and the GFP intensity was analyzed by flow cytometry. The bar chart presents the GFP intensity indicating the ROS levels in PC-12 cells under the indicated treatments. Data were collected from three independent experiments and expressed as the mean ± SD. ^∗∗∗p ≤ 0.001.
