|摘要:||Aim of this study: Phellinus igniarius (Linnearus: Fries) Quelet (Phellinus igniarius) has been used in oriental countries for treatment of various diseases including cancer. However, it is unclear how Phellinus igniarius exerts anticancer effects. Materials and methods: In this study the ethanolic extract from the fruiting body of Phellinus igniarius (EEPI) was used to evaluate the antiproliferative and antimetastatic effects in human hepatocarcinoma SK-Hep-1 cells and rat heart vascular endothelial cells (RHE cells). Results: We found that EEPI inhibited the proliferation of both cell lines in a dose-dependent manner, and the IC50 values at 48 h were 72 and 103 mu g/ml for SK-Hep-1 cells and RHE cells, respectively. EEPI at non- or sub-cytotoxic concentrations (25-100 mu g/ml) markedly inhibited the migration and invasion of SK-Hep-1 cells. EEPI added at 25 mu g/ml significantly decreased the secretion of matrix metalloproteinase-2 (MMP-2) (49%, p < 0.01) and vascular endothelial growth factor (VEGF) (13%, p < 0.05) in SK-Hep-1 cells. EEPI at 25 mu g/ml completely inhibited matrigel-induced tube formation in RHE cells. Importantly, EEPI (25 or 50 mu g/ml) in combination with oxaliplatin (Oxa) or 5-flurouracil (5-FU) synergistically inhibited the proliferation of SK-Hep-1 cells. Conclusion: These results demonstrate the antiproliferative and antimetastatic effects of EEPI in vitro and the potential of EEPI as an adjuvant for chemotherapy. (c) 2007 Elsevier Ireland Ltd.
