Changes in caspase-3 and DJ-1 expressions in the striatum in response to MPTP and acupuncture stimulations. MPTP administration increased caspase-3 expression and suppressed DJ-1 expression; however, acupuncture stimulation at GB34 alleviated them. Scale bar 200 µm. Data are shown as the means ± the standard errors of means. *p < 0.05 and **p < 0.01 versus the saline group, ^# p < 0.05, ^## p < 0.01 and ^### p < 0.001 versus the MPTP group, and ^† p < 0.05 versus the MPTP + SI3 group
