Angiogenesis Research Antibodies
Introduction
Embryonic vascular system undergoes a series of complex, highly regulated series of events involving differentiation, migration and association of primitive endothelial cells. This process is termed vasculogenesis. A further remodeling of the primitive vascular system forms the mature cardiovascular system. This process is known as angiogenesis (sprouting of new capillary vessels from pre-existing vasculature). Angiogenesis accounts for the formation of vasculature into previously avascular organs such as brain and kidney. Angiogenic activity in the adult is required during the normal tissue repair, and for the remodeling of the female reproductive organs (ovulation and placental development). Certain pathological conditions, such as tumor growth and diabetic retinopathy, also require angiogenesis. Recent studies have identified several proteolytic fragments or cryptic domains of proteins that act as inhibitors of angiogenesis. These include fragments of plasminogen such as Angiostatin protein (kringles 1-4) and kringles 1-5, C-terminal proteolytic fragment of Collagen XVIII (Endostatin protein), the NC10 domain of collagen 15 (Restin), the C-terminal hemopexin-like domain of MMP-2 (PEX), the N-terminal fragment of prolactin, and the N-terminally truncated platelet factor. The 20 kDa fragment of Collagen XVIII known as Endostatin protein inhibits tumor progression and induction of endothelial cell apoptosis. Administration of Endostatin protein to mice bearing certain tumors caused tumor regression without the development of drug resistance. Endostatin protein also inhibited systemic angiogenesis, primary tumor growth, and the development of primary metastatic lesions. It also reduced the levels of antiapoptotic proteins Bcl-2 and Bcl-xL and an increase in apoptosis of endothelial cells in vitro.
Angiostatin protein, a proteolytic fragment of plasminogen, is comprised of the first four kringle regions. It prevents the growth of endothelial cells, and its systemic administration inhibits the growth of primary carcinomas in mice. Kringles 1-3 fragment has a greater inhibitory activity than the kringles 1-4 fragment. The protease-activated kringles 1-5 is the most potent plasminogen fragment with over 50-fold greater endothelial cell specific inhibitory activity. Its systemic administration inhibited the growth of fibrosarcoma and significantly reduced neovascularization.
Angiogenin is a single polypeptide chain of 123 aa (mol wt ~14 kDa) secreted by tumor cells. It is a potent inhibitor of neovascularization. It specifically binds to endothelial cells and elicits second messenger systems. It has ribonucleolytic activity and is 33% identical to pancreatic RNAse A. Angiogenin has also been shown to undergo nuclear translocation in endothelial cells via receptor-mediated endocytosis and nuclear localization sequence-assisted nuclear import. Human and mouse angiogenin are 76% identical. The critical catalytic residues of human angiogenin are conserved in the mouse protein, as are the six cysteines necessary for disulfide bond formation.
