Angiogenesis plays a key role in tumor growth, progression and metastasis. The modulation of angiogenesis represents a potentially useful target for novel forms of anticancer therapy. Two such modulators are AGM-1470 (TNP-470, angioinhibin), which is a synthetic analog of the antibiotic fumagallin, and the monoclonal antibody TEC-11 to endoglin. We investigated the mechanisms of action of these modulators on human microvascular and macrovascular endothelial cells and on the transformed endothelial cell line ECV-304 in vitro. The administration of AGM-1470 or TEC-11 resulted in a significant inhibition of cell proliferation in all cell types used; this effect was reversible upon removal of these compounds from the culture medium. Furthermore, biochemical and morphological analyses showed that neither AGM-1470 or TEC-11 induce apoptosis. Both AGM-1470 and TEC-11 inhibited the production of urokinase-type plasminogen activator (u-PA), an enzyme involved in the early steps of neovascularization. Finally, the incubation of endothelial cells with both AGM-1470 and TEC-11 did not produce an additive effect on growth cell inhibition, apoptosis or u-PA production. Since both AGM 1470 and TEC-11 inhibit crucial events such as endothelial cell growth and protease production, our results provide a basis for their therapeutic use as angiostatic molecules in cancer.
