Abstract: The subject invention provides materials and methods useful in safely and effectively preventing pathological proliferation of blood vessels. The prevention of the over-proliferation of blood vessels according to the subject invention is particularly advantageous for treatment of certain ocular conditions including age-related macular degeneration (AMD), retinopathy of prematurity (ROP) and diabetic retinopathy. In preferred embodiments, the subject invention provides materials and methods for effective treatment of pathological ocular neovascularization using gene therapy. In a specific embodiment the materials and methods of the subject invention can be used to treat AMD.

Abstract: Compositions and methods for reducing neovascularization. Purified nucleic acid constructs and vectors encoding an anti-angiogenic protein operably linked to a GFAP promoter. Vectors can include at least one hypoxia regulated element, enhancer element and silencer element. Gene therapy methods for reducing, delaying or preventing neovascularization based on the nucleic acid constructs and vectors.
