To examine the effect of Xuefuzhuyutang on the metastasis of cancer, the following experiments were carried out. Before the main experiments, the cytotoxicity was measured by putting Xuefuzhuyutant sample in HT1080. Then zymography was made to examine the change of gelatinolytic activity. Western blotting was carried out to examine the changes of Fos, Jun, Ets, Erk, md JNK. In vitro invasion assay with transwells coated by collagen and matrigel was carried out. From the above results the following conclusions were obtained. 1. The experimental result about cytotoxicity of Xuefuzhuyutang agaitst HT1080 was a below. The stained cell count after being treated by by Xuefuzhuyutang sample $400{\mu}g/ml$ for 24 hours was 0.9% of total cells, and the stained cell count by Xuefuzhuyutang sample $100{\mu}g/ml$ was 1.5% of total cells. Both were near the level of control group which showed 0.6% stained. 2. The result of collagenase assay was as below. In Xuefuzhuyutang sample $400{\mu}g/ml$, MMP2 was reduced as compared with TPA control group, and the band of MMP-9 induced by TPA disapappeared. In Xuefuzhuyutang samle $800{\mu}g/ml$ both bands of MMP-2 and MMP-9 disapeared. 3. The results of western blots for Jun, Fos, Ets, Erk, JNK were a below. In Xuefuzhuyutang sample $200{\mu}g/ml$, Ets was reduced, and Jun, Fos were increased. 4 The result of invasion assay was as below. The number of cells which migrated across transwell membrane in Xuefuzhuyutang-treated group was less than that of control(+TPA) group. From the above results, it was concluded that Xuefuzhuyutang might inhibit the activity of collagenase not by the MMP-2, MMP-9 promoter but by the other way.
