Original Research


More than 90% of the cancer-associated mortality is attributed to its metastasis. Numerous studies demonstrated that natural steroidal saponins from plants had the capacity to inhibit lung cancer metastasis. Dioscin-6’-O-acetate (DA) was a novel steroidal saponin first obtained from the rhizomes of Dioscorea althaeoides R. Knuth. Our previous study indicated that it suppressed lung cancer cell proliferation via inducing cell-cycle arrest and enhancing caspase-dependent apoptosis. Until now, there were still no reports on its anti-migration activity. In the present study, we further verified the anti-proliferation and apoptosis-inducing effects and investigated the anti-migration effects of DA on human NSCLC (NCI-H460, NCI-H1299, NCI-H520) and SCLC (NCI-H446) cells for the first time. To clarify the possible mechanisms, western blot and/or RT-PCR analysis were used. The results revealed that DA treatment increased the levels of caspase 3, 8, 9, and Bax and markedly decreased the expression of bcl-2, PCNA, MMP-2, MMP-9, and NF-κB. Docking study indicated that DA presented strong affinity with the key metastasis-related proteins, such as MMP-2, MMP-9, and NF-κB. We proposed that DA might suppress lung cancer proliferation by downregulating PCNA, induce lung cancer apoptosis via activation of caspase-dependent apoptosis pathways, and inhibit lung cancer migration possibly by targeting MMP-2/9 through NF-κB signaling suppression. The findings would provide the foundation for the clinical use of DA in future.
