| Abstrakt: | Aim: To study the effects of non-cytotoxic concentrations of docetaxel on some important angiogenic factors of LS174T Cells. Methods: The non-cytotoxic concentration of docetaxel and the activity of gelatinase were determined with MTT and gelatin zymography respectively, the expression of VEGF(vascular endothelial growth factor), bFGF (basic fibroblast growth factor), MMP (matrix metalloproteinase) 2 and MMP 9 was investigated with RT-PCR and Western blot. Results: The maximum non-cytotoxic concentration of docetaxel on LS174T Cells was 1.0 ng/ml. Compared with the solvent control group, 0.1, 0.5, 1.0 ng/ml of docetaxel could downregulate the expression of VEGF, bFGF, MMP 2 and MMP 9 and suppress the activity of gelatinase. Conclusion: Our study suggests that the non-cytotoxic concentrations of docetaxel have strong antiangiogenic activity on LS174T Cells, which suggests docetaxel may be a promising antiangiogenic agent. |
