Anti-Angiogenesis: A New Weapon In Cancer Therapy

To date, Folkman's angiostatin and endostatin proteins have completely eradicated tumors while avoiding side effects in mice. This research suggests that mechanisms that inhibit angiogenesis will have potential as cancer therapeutics.

If you are working on a story regarding the breakthrough of anti-angiogenesis for cancer therapy, you might be interested in related work being done by Ribozyme Pharmaceuticals, Inc. (RPI). Through the use of ribozymes, short RNA molecules that are designed to cleave specific RNA sequences and thereby inhibit the synthesis of disease-causing proteins, RPI is using an anti-VEGF receptor ribozyme to inhibit angiogenesis and thus restrain tumor growth. Preclinical studies have indicated efficacy of the ribozyme as an anti-angiogenic agent in multiple animal models in various cancers and in the eye. Most recently, the anti-VEGF receptor ribozyme has demonstrated the ability to inhibit the development of tumor blood vessels in mice bearing Lewis Lung Carcinoma, resulting in the inhibition of both tumor growth and metastasis.
