-induced apoptosis in SH-SY5Y neuroblastoma cells. (A) Melittin increased the cell viability of H2O2-treated SH-SY5Y cells as determined by MTT assay. (B) Melittin decreased LDH release as determined using a cytotoxicity detection kit. Data are expressed as mean ± SEM from three independent experiments. Bars with different letters indicate significant differences at p < 0.05.
