Abstract
Statement of the Problem: The antitumor activity of vandetanib (a multiple signal transduction inhibitor including the RET tyrosine kinase, epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF) receptor (VEGFR), ERK and with antiangiogenic activity), has been evaluated in primary anaplastic thyroid cancer (ATC) cells, in the human cell line 8305C (undifferentiated thyroid cancer) and in an ATC-cell line (AF). Methodology & Theoretical Orientation: Vandetanib (1 nM, 100 nM, 1 mcM, 10 mcM, 25 mcM, 50 mcM) was tested: in primary ATC cells, in the 8305C continuous Kcell line, and in AF cells; and in 8305C cells injected in CD nu/nu mice. Findings: Vandetanib was able to reduce significantly ATC cell proliferation (P<0.01, ANOVA), induced apoptosis in a dosedependent manner (P<0.001, ANOVA), and inhibited migration (P<0.01) and invasion (P<0.001). Moreover, vandetanib inhibited EGFR, AKT and ERK1/2 phosphorylation and down-regulated cyclin D1 in ATC cells. In 8305C and AF cells, vandetanib inhibited significantly the proliferation, inducing also apoptosis. 8305C cells were injected sc in CD nu/nu mice and tumor masses became detectable after 30 days. Vandetanib (25 mg/kg/die) inhibited significantly tumor growth and VEGF-A expression and microvessel density in 8305C tumor tissues. Conclusion & Significance: The antineoplastic activity of vandetanib in ATC is the result of: a) an anti-proliferative activity; b) an increased apoptosis; c) inhibition of both migration, and invasion; d) and inhibition of the cancer neovascularization, too. The antitumor and antiangiogenic effect of vandetanib is promising in ATC, opening the way to a future clinical evaluation. Recent Publications 1.
