NCIt definition : A recombinant human proteolytic fragment of the C-terminal end of type XVIII collagen.
Endostatin induces microvascular endothelial cell apoptosis and inhibits endothelial
proliferation and angiogenesis, which may result in a reduction in tumor burden. This
agent also may decrease hepatic metastasis by inhibiting proinflammatory cytokines
and vascular cell adhesion molecule (VCAM)-dependent cell attachment to the hepatic
microvasculature. (NCI04);
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of cancer. Endostatin is made
from a type of collagen (a protein found in cartilage and other connective tissue).
It may prevent the growth of new blood vessels that tumors need to grow. Endostatin
is a type of antiangiogenesis agent.;
