Abstract:
Objective To study the effects and the mechanism of oridonin on inhibiting the invasion and migration abilities of human melanoma A375 cells. Methods Human melanoma A375 cells were cultured and treated respectively with indicated concentrations of oridonin by cell culture technique. The proliferation rate was detected by CCK-8 method. The migration ability was measured by wound healing assay. The invasion ability was examined by Transwell assay. The adhesion capabilities were evaluated by adhesion assay. The epithelial-mesenchymal transition (EMT) and matrix metalloproteinases (MMPs) related protein expression levels were determined by Western blotting. Results CCK-8 assay showed the median inhibition concentration (IC50) of 48 h was 47.94 μmol/L. Oridonin (5, 10, and 20 μmol/L) inhibited the migration, invasion and adhesion abilities of human melanoma A375 cells in a dose-dependent manner (P < 0.05). After oridonin treatment, the protein expression levels of E-cadherin increased significantly (P < 0.05) and the protein levels of Snail, N-cadherin, vimentin, MMP-2, and MMP-9 decreased significantly (P < 0.05). Conclusion Oridonin inhibits the migration, invasion and adhesion abilities of human melanoma A375 cells. The mechanism may be related with the regulating effects of oridonin on EMT and MMPs.
