Abstract

Arctigenin, a dibenzylbutyrolactone lignan, enhances cisplatin-mediated cell apoptosis in cancer cells. Here, we sought to investigate the effects of arctigenin on cisplatin-treated non-small-cell lung cancer (NSCLC) H460 cells. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and annexin-V/propidium iodide staining were performed to analyze the proliferation and apoptosis of H460 cells. Arctigenin dose-dependently suppressed cell proliferation and potentiated cell apoptosis, coupled with increased cleavage of caspase-3 and poly(ADP-ribose) polymerase. Moreover, arctigenin sensitized H460 cells to cisplatin-induced proliferation inhibition and apoptosis. Arctigenin alone or in combination with cisplatin had a significantly lower amount of survivin. Ectopic expression of survivin decreased cell apoptosis induced by arctigenin (P < 0.05) or in combination with cisplatin (P < 0.01). Moreover, arctigenin (P < 0.05) or in combination with cisplatin (P < 0.01) induced G1/G0 cell-cycle arrest. Our data provide evidence that arctigenin has a therapeutic potential in combina-tion with chemotherapeutic agents for NSLC.
