The purpose of this study was to examine the anti-metastatic effect of Juniperus chinensis extract by inhibition of galectin-3 expression. For this study, we carried out the experiment of galectin-3 expression assay and in vivo metastasis mouse model bearing colon 26-M3.1 lung carcinoma, and also MMP-1, MMP-2 and MMP-9 inhibitory assays relating metastasis mechanism. J. chinensis extract significantly showed the inhibitory effect of basal expression and MNNG-induced expression of galectin-3 in colon 26-M3.1 lung carcinoma at the all tested doses (5, 50 and $500{\mu}g/m{\ell}$). In case of the inhibition of MMP-1, MMP-2 and MMP-9, the weak activity was showed at the doses of 50 and $500{\mu}g/m{\ell}$ and was not detected at the dose of $5{\mu}g/m{\ell}$. However, J. chinensis extract significantly showed the anti-metastatic activity on mouse mode bearing colon 26-M3.1 lung carcinoma. Therefore, this study strongly suggests that J. chinensis is a potent inhibitor of galectin-3 expression, and holds great promise for use in inhibiting metastasis induced by elevated expression of galectin-3.
