Prdx-2 overexpression protected SH-SY5Y cells from MPP+ neurotoxicity. (A) The viability of SH-SY5Y cells was analyzed by the CCK8 assay following transfection with the Prdx-2 overexpression plasmid. (B) Representative WB bands and protein density differences among four groups. (C) A densitometric analysis of protein expression of Prdx-2 among four groups. (D) A densitometric analysis of protein expression of SIRT1 among four groups. (E) A densitometric analysis of protein expression of TH among four groups. (F) A densitometric analysis of protein expression of Bax/Bcl-2 among four groups. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
