Fig. 6From: EF24 exerts cytotoxicity against NSCLC via inducing ROS accumulationEF24 induces cytotoxicity is restored by ROS scavengers. A549 and H520 cells were treated with 4 μM EF24 for 48 h with or without CAT and NAC employed 2 h before EF24 treatment, after that cell viability using MTT assay (A) and apoptotic cells using Annexin-V & PI staining (B) were detected. Three independent experiments were performed and the results statistically analyzed as means ± SD, *P < 0.05, **P < 0.01, ***P < 0.01Back to article page
