Lipid-Soluble Ginseng Extract Inhibits Invasion and Metastasis of B16F10 Melanoma Cells

다국어 초록 (Multilingual Abstract)

This study was performed to elucidate the effect of a lipid-soluble ginseng extract (LSGE) on cancer invasion and metastasis. The LSGE, even at noncytotoxic concentrations, potently inhibited invasion and migration of B16F10 mouse melanoma cells in a dose-dependent manner. In the presence of 3 lg/mL of LSGE, the invasion and migration of B16F10 cells were significantly inhibited by 98.1% and 71.4%, respectively. Furthermore, the LSGE decreased mRNA and protein levels of matrix metalloproteinase (MMP)-2 in B16F10 cells, leading to a decrease in MMP-2 activity. After B16F10 cells were intravenously injected in the tail vein of C57BL/6 mice, 1000 mg/kg/day of LSGE was orally administered for 13 days, after which lung metastasis of cancer cells was inhibited by 59.3%. These findings indicate that LSGE inhibits cancer cell invasion and migration in vitro and lung metastasis of melanoma cells in vivo by inhibiting MMP-2 expression.
