Effects of CP on cell viability and Nurr1 and its regulating neurotrophic factors. Effects of CP on PC12 and differentiated PC12 cell neuronal damage (a, b). The protein levels of Nurr1 and its regulating neurotrophic factors were measured by western blotting in differentiated PC12 cells (c) and the mouse SNPC (d). Differentiated PC12 cells were pretreated with CP and an ERK inhibitor (SCH) for 10 h, and the protein levels of Nurr1 and its regulating neurotrophic factors were measured by western blotting (e). β-Actin protein was used as an internal control. Bar graphs represent the relative expression of Nurr1 (f), TH (g), DDC (h), DAT (i), and VMAT2 (j) for (c)–(e). Values are presented as means ± S.E.M. p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001 compared with the control group and #p < 0.05 and ##p < 0.01 compared with the CP-treated group.
