Effect of melittin on protein expression of Bcl-2 and Bax in H
-treated SH-SY5Y cells. (A) Melittin inhibited the decrease of Bcl-2 protein as measured by Western blot analysis. (B) Melittin blocked the increase of Bax protein as determined by Western blot analysis. (C) Melittin caused a low Bax/Bcl-2 protein ratio. Data are expressed as mean ± SEM from 3 independent experiments. Bars with different letters indicate significant differences at p < 0.05.
