Echinacoside Protects against 6-Hydroxydopamine-Induced Mitochondrial Dysfunction and Inflammatory Responses in PC12 Cells via Reducing ROS Production

Figure 2

Effect of echinacoside on morphological change and viability of PC12 cells injured by 6-OHDA. (A) Effect of different concentration of echinacoside on cell viability in PC12 cells. (B) Morphological changes induced by 6-OHDA treatment observed by light microscopy. Representative photographs: (a) untreated group; (b) 6-OHDA-treated group; (c) 6-OHDA+ echinacoside 0.1 μM; (d) 6-OHDA+ echinacoside 1 μM; and (e) 6-OHDA+ echinacoside 10 μM. (C) Effect of echinacoside on cell viability changes induced by 6-OHDA in PC12 cells. Data are expressed as percentage of untreated cells. Data are the mean ± SD, , ## versus untreated group; versus vehicle group.
