EGCG and MPP + affect PC12 cell viability. (A) MPP+-induced PC12 cell viability. MPP+ concentrations were 0, 125, 250, 500, 1000 and 2000 μmol/L (*P < 0.05;**P < 0.01 vs. vehicle control). (B) PC12 cell viability after EGCG treatment. EGCG concentrations were 0, 2.5, 5, 10, 20 and 40 μmol/L (**P < 0.01 vs. vehicle control). (C) Treatment with EGCG and then MPP+ affects PC12 cell viability. Groups were: control, 500 μmol/L MPP+, 500 μmol/L MPP+ + EGCG (1.25, 2.5, 5 or 10 μmol/L) (#P < 0.05 vs. vehicle control, **P < 0.01 vs. MPP+ treatment alone).
