Figure 1From: Dihydroartemisinin (DHA) induces caspase-3-dependent apoptosis in human lung adenocarcinoma ASTC-a-1 cellsCell viability was measured by CCK-8 assay via concentration- and time-dependent manners in vitro. a ASTC-a-1cells were seeded into 96-well flatbottomed microplate and incubated with various concentrations of DHA for 48 h. b Cells were seeded into 96-well flatbottomed microplate and incubated with 20 μg/ml of DHA for the indicated times. Data analyzed with SPSS10.0 software are expressed as mean ± SD. n = 4 wells for all CCK-8 assay. *P < 0.05, **P < 0.01, compared with control.Back to article page
