Summary for Patent: 9,802,984
Title:Biomimetic peptide and biodegradable delivery platform for the treatment of angiogenesis- and lymphangiogenesis-dependent diseases
Abstract: Mimetic peptides having anti-angiogenic and anti-tumorigenic properties and methods of their use for treating cancer, ocular diseases, such as age-related macular degeneration, and other-angiogenesis-dependent diseases are disclosed. More particularly, an isolated peptide comprising the amino acid sequence LRRFSTAPFAFIDINDVINF, which exhibits anti-angiogenic activity in endothelial cell proliferation, migration, adhesion, and tube formation assays, anti-migratory activity in human breast cancer cells in vitro, anti-angiogenic and anti-tumorigenic activity in vivo in breast cancer xenograft models, and age-related macular degeneration models is disclosed. The isolate peptide also exhibits anti-lymphangiogenic and directly anti-tumorigenic properties.
Inventor(s): Popel; Aleksander S. (Lutherville-Timonium, MD), Pandey; Niranjan B. (White Marsh, MD), Lee; Esak (Windsor Mill, MD), Green; Jordan J. (Nottingham, MD), Shmueli; Ron B. (Baltimore, MD)
Assignee: THE JOHNS HOPKINS UNIVERSITY (Baltimore, MD)
