Objective:To evaluate the anti-tumor effect in vitro of coix seed oil injection on the human liver cancer cell SMMC-7721 and study the mechanism of action.Methods: Human HCC cells were treated with KLT.CCK-8 cell viability assay,scratch assay,transwell assay and matrigel sprout assay were performed to investigate the effect of KLT on cell proliferation,migration and invasion.Impact of KLT on apoptosis and cell cycle of cancer cells were measured by flowcytometry.The expression level of target genes of KLT in cancer cells were studied by Western blot.Results: KLT suppressed the cell proliferation,migration and invasion of human HCC cells.Cell cycle of HCC cells was arrested in G2/M phase when treated with KLT and late stage of apoptosis was observed.KLT was capable of inducing the expression of cyclin B1,while down-regulating the expression of cyclin D1,cyclin E.Conclusion: KLT possesses well acknowledged anti-tumor activity in vitro,which may result from cell cycle arrest,apoptosis,down-regulation of oncogenes.
