Effect of eupatorium japonicum extract on the metastasis, invasion and adhesion of MDA-MB-231 human breast cancer cells

초록

The metastatic effect of Eupatorium japonicum extract (EJE) on MDA-MB-231 human breast cancer cells was investigated. MDA-MB-231 cells were treated with various concentrations of EJE (0, 5, 10 and 20 μg/mL). EJE inhibited cell migration, invasion and adhesion of MDA-MB-231 cells in dose-dependent manners. Gelatin zymography exhibited that EJE significantly down regulated secretion of matrix metalloproteinase (MMP)-9 and MMP-2. EJE decreased the protein levels of tissue inhibitor of metalloproteinase (TIMP)-1 but increased TIMP-2 levels. Additionally, EJE reduced the protein and mRNA levels of urokinase-type plasminogen activator (uPA), vascular endothelial growth factor (VEGF) and intercellular adhesion molecule (ICAM). In several solvent fractions of EJE, the hexane fraction markedly decreased MDAMB- 231 cell migration. Thus, these finding suggest that EJE may be a potential antimetastatic agent, which can considerably inhibit the metastatic and invasive capacity of breast cancer cells. © The Korean Society of Food Science and Technology.
