Fig. 1

Representative cropped blot with relative expression level of TH in the SN of different animal groups. The full length blots are presented in supplementary figure 1. C = control group; PQ = Paraquat (alone)-induced group; PQ+PSE = PQ-induced group treated with PSE; PQ+PJ = PQ-induced group treated with PJ. Data are expressed as mean ± S.D. of 10 mice in each group. ***: P < 0.001 compared with control group; ###: P < 0.001 compared with PQ group
