Abstract: Angiogenesis may be initiated or increased through the use of gamma-secretase inhibitors. The gamma-secretase inhibitor can be a dipeptide class, sulfonamide class, transition state mimic class, benzodiazepine class, or benzocaprolactam class gamma secretase inhibitor. Methods for initiating and increasing angiogenesis are used for disease prevention and treatment as well as for generating research models.

Abstract: The present invention relates to polynucleotides and proteins associated with vasculogenesis- and angiogenesis-related disorders. The invention further relates to methods for the identification of compounds that modulate the expression of angiogenesis-related genes and gene products and to using such compounds as therapeutic agents in the treatment of angiogenesis-related disorders. The invention also relates to methods for the diagnostic evaluation, genetic testing and prognosis of angiogenesis-related disorders, and to methods and compositions for the treatment these disorders.
