Effects of PE and pomegranate phenolics on cellular caspase 3/7 (A), caspase 8 (B) and caspase 9 (C) in HaCaT cells exposed to H2O2. HaCaT cells were incubated with PE, PA, EA, and UA for 12 h before H2O2 induction. Significances were defined as compared with control group: ##P < 0.01; compared with H2O2-treated group: *P< 0.05, **P< 0.01, ***P< 0.001. Values are presented as means ± S.D. from three replicates.
