Abstract
Ivalin, an eudesmane-type sesquiterpene compound, was isolated from the Chinese herb Carpesium divaricatum in our chemistry group. In this study, we investigated the anti-migration and anti-invasion activities and underlying mechanisms of Ivalin in breast cancer cells in vitro. Cell viability was evaluated using the MTT assay, Western blotting was used to determine the expression of E-cadherin, N-cadherin, vimentin and ZEB1, and mRNA levels were analyzed by qPCR. The anti-migration and anti-invasion effects of Ivalin were measured by wound-healing and Transwell assays. In this connection, Ivalin treatment reduced the mRNA and protein expressions of ZEB1 as well as N-cadherin and vimentin expression in various breast cancer cells. E-cadherin expression was enhanced by Ivalin in the same cells, which implied that Ivalin depressed the process of epithelial-to-mesenchymal transition (EMT). Our results revealed that Ivalin significantly inhibited cell proliferation, migration and invasion in breast cancer cells in a dose-dependent manner in vitro. This study suggests that Ivalin may merit further investigation as a potential therapeutic leading compound for the treatment of breast cancer migration and invasion.
