The roots of Angelica dahurica have long been used as a traditional medicine in Korea to treat various diseases such as toothache and cold. In this study, we investigated the effect of ethanol extract from the roots of this plant on metastatic melanoma, a highly aggressive skin cancer, in B16F10 melanoma cells and B16F10 cell inoculated-C57BL/6 mice. Our results showed that the ethanol extracts of Angelicae dahuricae Radix (EEAD) suppressed cell growth and induced apoptotic cell death in B16F10 cells. EEAD also activated the mitochondria-mediated intrinsic apoptosis pathway, with decreased mitochondrial membrane potential, and increased production of intracellular reactive oxygen species and ration of Bax/Bcl-2 expression. Furthermore, EEAD reduced the migration, invasion, and colony formation of B16F10 cells through the reduced expression and activity of matrix metalloproteinase (MMP)-2 and -9. In addition, in vivo results demonstrated that oral administration of EEAD inhibited lactate dehydrogenase activity, hepatotoxicity, and nephrotoxicity without weight loss in B16F10 cell inoculated-mice. Importantly, EEAD was able to markedly suppress lung hypertrophy, the incidence of B16F10 cells lung metastasis, and the expression of tumor necrosis factor-alpha in lung tissue. Taken together, our findings suggest that EEAD may be useful for managing metastasis and growth of malignant cancers, including melanoma.
