Figure 5. PCA reduced cytotoxicity and apoptosis in MPP+-incubated SH-SY5Y cells. (A) Histogram showing cell viability at different dosages of PCA. (B) Quantification analysis of apoptosis rate. (C) Representative pictures of flow cytometry for apoptosis in each group. Data were presented as mean ± S.D., n = 6; **P< 0.01vs. control group; #P< 0.05 vs. MPP+group.
