1 Impact of tumor cell VEGF expression on the in vivo efficacy of vandetanib (ZACTIMA; ZD6474). vandetanib vascular endothelial growth factor A Mus musculus
2 In the current study, the impact of VEGF expression on the response of tumors to the VEGFR2 associated tyrosine kinase inhibitor vandetanib was evaluated. vandetanib vascular endothelial growth factor A Mus musculus
3 An intradermal angiogenesis assay was used to demonstrate that a 4-day treatment with vandetanib (50 mg/kg/day) was able to significantly inhibit blood vessel growth induced by both parental and high VEGF-expressing tumor cell clones. vandetanib vascular endothelial growth factor A Mus musculus
4 In the HT29 tumor model, treatment response to vandetanib (50 mg/kg/day, Monday-Friday for 2 weeks) was greatest in xenografts derived from the highest VEGF-expressing cell clones. vandetanib vascular endothelial growth factor A Mus musculus
5 The present findings indicate that vandetanib therapy effectively counteracted the aggressive feature of tumor growth resulting from VEGF over-expressing tumor cells and suggest that such tumors may be particularly well suited for anti-VEGF interventions. vandetanib vascular endothelial growth factor A Mus musculus
6 The present findings indicate that vandetanib therapy effectively counteracted the aggressive feature of tumor growth resulting from VEGF over-expressing tumor cells and suggest that such tumors may be particularly well suited for anti-VEGF interventions. vandetanib vascular endothelial growth factor A Mus musculus
