Tumors require the formation of new blood vessels termed, angiogenesis, to grow. Targeting angiogenesis provides a novel approach for cancer therapy that rivals conventional therapy since drug resistance and tissue toxicity issues are avoided. Tumor angiogenesis depends on a balance between tumor-dependent angiogenic factors like VEGF (vascular endothelial growth factor) and host anti-angiogenic peptides like endostatin and angiostatin. The ability to alter this balance by favoring the anti-angiogenic effect by treatment with exogenous endostatin and angiostatin has been successfully demonstrated. However, a major difficulty in translating these strategies to the clinic is the lack of large quantities of these peptides for long-term treatment. An alternative strategy to disturb this balance is to disrupt VEGF or other angiogenic factor production.
