SW induces apoptosis in Calu-3, H1299 and SPC-A-1 cells. (A) Calu-3, H1299 and SPC-A-1 cells were treated with the indicated concentrations of SW for 48 h. DNA was extracted and analyzed on 2% agarose gel. (B) Calu-3, H1299 and SPC-A-1 cells were treated with the indicated concentrations of SW for 24 h, followed by Annexin V / PI staining and FCM analysis. The Annexin V positive cells were regarded as apoptotic. The results are mean ± SD and representative of three independent experiments. * p < 0.05, ** p < 0.01 versus the control group (0 μM).
