Abstract
Angiogenesis is a requirement for solid tumor growth. Therefore, inhibition of this neovascularization is one mechanism by which restoration of wtp53 function may lead to tumor regression. Here we report that adenoviral vector–mediated wild-type p53 transduction results in growth inhibition of squamous cell carcinoma of the head and neck tumor cells both in vitro and in a xenograft mouse model. This growth inhibition is associated with the down-regulation of the expression of fibroblast growth factor binding protein, a secreted protein required for the activation of angiogenic factor basic FGF. These findings suggest that wtp53-induced tumor regression is due, at least in part, to antiangiogenesis mediated by the downmodulation of fibroblast growth factor binding protein.
