Cell viability and mRNA expressions of SOD2 and HMOX1 in PLE and MPP⁺ treated cells. a PLE treatment recovered 1 mM MPP⁺ treated cell viability depending on concentrations of PLE. The results suggested PLE has neuroprotective effects against MPP⁺-induced apoptosis. b PLE treatment didn’t alter mRNA expressions of SOD2 in 1 mM MPP⁺ treated SH-SY5Y cells. c PLE treatment further activated mRNA expressions of HMOX1 in 1 mM MPP⁺ treated SH-SY5Y cells. The results suggested PLE has neuroprotective effects on antioxidant function.; The data was indicated as the mean ± S.E.M. P < 0.05 was defined statistical significance. One-way ANOVA followed by Duncan post hoc test
