  • collagen alpha-1(XVIII) chain
  • endostatin

General information

  • Endostatin binding to alpha-5/beta-1 integrin leads to the inhibition of focal adhesion kinase/c-Raf/MEK1/2/p38/ERK1 mitogen-activated protein kinase pathway, with no effect on phosphatidylinositol 3-kinase/Akt/mTOR/4E-BP1 and Cap-dependent translation. [1]
  • Product of the COL18A1-gene.
  • Endostatin potently inhibits endothelial cell proliferation and angiogenesis. May inhibit angiogenesis by binding to the heparan sulfate proteoglycans involved in growth factor signaling. [2]
  • Tumstatin prevents angiogenesis via inhibition of endothelial cell proliferation and promotion of apoptosis with no effect on migration, whereas human endostatin prevents endothelial cell migration with no effect on proliferation. [1]
  • Endostatin is the C-terminal antiangiogenic fragment of the extracellular matrix protein collagen XVIII, and is generated by tumor-derived proteases. [3]
  • Endostatin can specifically inhibit endothelial proliferation and potently inhibit angiogenesis and tumor growth. [4]
  • Endostatin, the proteolytic fragment of collagen XVIII, induces vasorelaxation. [5]
