From: EF24 exerts cytotoxicity against NSCLC via inducing ROS accumulation
EF24 induces apoptosis in NSCLC cells. A A549, SPC-A1, H460 and H520 cells were treated with or without indicated concentrations of EF24 respectively for 48 h and subjected to apoptosis assay using Annexin-V & PI staining. B The expression of apoptotic marker Fas in cells were determined. Three independent experiments were performed and the results statistically analyzed as means ± SD, *P < 0.05, **P < 0.01, ***P < 0.01
