Effect of PF on the expressions of Bax/Bcl-2 proteins in Aβ25–35-induced SH-SY5Y cells. Cells were pretreated with or without various concentrations of PF (2, 10, 50 μM) for 24 h and exposed to Aβ25–35 (25 μM) for another 24 h. a Assessment of Bax and Bcl-2 protein levels in SH-SY5Y cells by Western blotting. b Effect of PF on the ratio of values of Bax/Bcl-2. The results are shown as mean ± SEM of three experiments and each included triplicate sets. **p < 0.01 versus control; ## p < 0.01 versus Aβ25–35 alone
