Figure 8. PCA increased the expressions of PLK2 and activated p-GSK3β/Nrf2 pathway in MPP+-incubated SH-SY5Y cells. (A) Representative western blot bands of PLK2, α-Syn, p-GSK3β, GSK3β, Nrf2, tubulin and Histone H3. (B–E) Quantification of PLK2, p-GSK3β/ GSK3β and nucleus Nrf2 levels in cells. Data were presented as mean ± S.D., n = 6; *P < 0.05 vs. control group; #P< 0.05 vs. MPP+group.
