背景信息

Endostatin, a 20-kDa C-terminal fragment derived from collagen alpha-1(XVIII) chain (COL18A1), is an endogenously produced inhibitor of angiogenesis. Many different proteases are able to cleave the NC1 domain of collagen alpha-1(XVIII) chain to produce endostatin including cathepsins L, B, and K, elastase. Endostatin inhibits proliferation and migration of endothelial cells, angiogenesis, and tumor growth. It may interfere with the pro-angiogenic action of growth factors such as basic fibroblast growth factor (bFGF/FGF-2) and vascular endothelial growth factor (VEGF).
