Extract of Artemisia lavandulaefolia Inhibits In Vitro Angiogenesis in Human Umbilical Vein Endothelial Cells

Angiogenesis is important processes for tumor growth and metastasis. Anti-angiogenesis target therapy has recently been known to be new anti-cancer therapeutic strategies. Natural products such as traditional medicine comprise a major source of angiogenesis inhibitors. Artemisia lavandulaefolia has been known to use in the traditional medical practices. However, its molecular mechanism on the tumor protection and therapy was not clearly elucidated. In this study, we investigated the possibility that extract of A. lavandulaefolia inhibits in vitro angiogenesis. Therefore, we examined the effect of extract of A. lavandulaefolia on the vascular network formation of human umbilical vein endothelial cells (HUVECs). We found that the treatment of A. lavandulaefolia extract suppressed the tube formation of HUVECs without any influence on the viability of HUVECs. In addition, extract of A. lavandulaefolia inhibited the migration and invasion of HUVECs. These results suggest that extract of A. lavandulaefolia could be act for an angiogenic inhibitor.
