In an attempt to elucidate the mechanism(s) of action of thalidomide, a reportedly antiangiogenic molecule recently tested in the treatment of relapsing malignant gliomas, we performed an in vitro study on the following parameters: (a) effect of thalidomide on proliferation of endothelial cells; (b) effect of thalidomide on expression of αvβ3 integrin on the surface of endothelial cells; (c) effect of thalidomide on the release by endothelial cells of MMP-2, IL-8 and TNF-α. The results show that thalidomide inhibits endothelial cell proliferation induced by bFGF and VEGF, more so if the cells are grown on vitronectin; moreover, treatment with thalidomide reduces the release of MMP-2 and IL-8 by endothelial cells, suggesting a further pathway for the antiangiogenic activity of drug. On the other hand, thalidomide does not modify expression of αvβ3 on endothelial cells.
