Figure 5. Cu/Zn–SOD protein levels in MPP+-treated VM neurons with apo-Lf or holo-Lf pretreatment.

Figure 5

(A) Western blots were applied to detect Cu/Zn–SOD protein levels. Cu/Zn–SOD protein level was down-regulated in VM neurons by MPP+. Apo-Lf or holo-Lf increased the expression of Cu/Zn–SOD in VM neurons compared with the control group. Apo-Lf or holo-Lf pretreatment reversed the decrease of Cu/Zn–SOD expression in MPP+-treated cells. β-actin was used as a loading control. (B) Statistical analysis. Data were presented as the ratio of Cu/Zn–SOD to β-actin. Each bar represented the mean ± S.E.M. *P < 0.05, compared with the control; #P < 0.05, compared with MPP+ group; n = 6.
