Effect of FFBJ or FFOJ on cell death induced by H₂O₂. The cells were treated for 18 h with FFBJ or FFOJ followed by incubation with 200 μM H₂O₂ for additional 2 h. PI-positive cells were determined by flow cytometry collecting the emission signal in the FL-3 channel. Data represent means ± SEM of three separate experiments. versus control cells and versus H₂O₂-treated cells.
