Effects of CP on MPTP-induced mitochondria-mediated apoptosis. Seven days after the last MPTP treatment, mitochondria-induced apoptotic factors (Bcl-2, Bax, Cyt-c, cleaved caspase-9, cleaved caspase-3, and PARP1) were measured by western blotting (a). Differentiated PC12 cells were treated with CP and exposed to MPP+ for 48 h. Moreover, red and green (b) and the ratio (c) of these fluoresces of mitochondrial membrane potential were expressed as a percentage of control. Effects of CP on MPTP-induced survival-related GDNF signaling. Its factors (GDNF and Ret) were measured by western blotting (d) and ELISA kit (e). Values are presented as . compared with the control group and or compared with the MPP+- or MPTP-treated group.
