Effects of oridonin on invasion and migration of human hepatocellular carcinoma MHCC-97H cells / 中国病理生理杂志

ABSTRACT

AIM: To investigate the effects of oridonin on the invasion and migration of hepatocelluar carcinoma cells.METHODS: Human hepatocelluar carcinoma MHCC-97H cells were cultured and treated with 5, 10 or 20 μmol/L oridonin.The migration ability was measured by wound healing assay.The invasion ability was examined by Transwell invasion assay.The adhesion capabilities were evaluated by adhesion assay.The protein levels of LIM kinase-1 (LIMK-1), cofilin and phosphorylated cofilin (p-cofilin) were determined by Western blot.RESULTS: Oridonin inhibited the migration, invasion and adhesion abilities of MHCC-97H cells in a dose-dependent manner (P<0.05).After oridonin treatment, the expression of cofilin had no obvious change, but the protein levels of LIMK-1 and p-cofilin decreased significantly.CONCLUSION: Oridonin inhibits the invasion and migration of MHCC-97H cells.The mechanism may be related with the regulatory effect of oridonin on LIMK-1/cofilin signal transduction pathway.
