The migration of vascular smooth muscle cells (VSMC) may play a key role in the development of atherosclerosis. Evodia officinalis DODE (EO), an eminent herbal plant, has been widely used in traditional Korean medicine for the treatment of vascular diseases such as hypertension. The crude extract of EO contains phenolic compounds that are effective in protecting liver microsomes, hepatocytes, and erythrocytes against oxidative damage. Also, several active components such as tanshinones, D(+) 3,4-dihydroxyphe
nol lactic acid, protocatechuic aldehyde, salvianolic acids and rosmarinic acid have been isolated and identified. But EO has been little found to have an anti-inflammatory and anti-migration activity. Moreover, little is known about its mechanism of action. This study was evaluated to elucidate the inhibitory potential of EO on human aortic smooth muscle cells (HASMC) migration and inflammatory responses. Cytotoxic activity of EO on HASMC was using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. EO decreased TNF-α-induced IL-8, IL-6 production, and intracellular ICAM-1 and VCAM-1 expression. The matrigel migration assay showed that EO effectively inhibited the TNF-α-induced migration of HASMC. Moreover, EO effectively decreased TNF-α-induced phospho-I-Bκ-α. These results indicate that EO has potential as an anti-inflammatory and -migration activity.
