Effects of CS on caspase activation in A549 and CL1-5 cells. a Cells were treated with the indicated concentrations of CS for 24 h. Total cell proteins were extracted and immunoblotted with antibodies to detect the cleaved forms of caspase-8, caspase-9, caspase-3, and PARP. b Cells were treated with CS (250 ng/ml) and/or the indicated caspase inhibitor for 24 h, and then cell viability was analyzed by the MTT assay. The means ± SD of the experimental triplicates are presented in the bar graph. All data are representative of three independent experiments with similar results. **P value <0.01, ***P value <0.001 compared with the control group
