Angiostatin

Angiostatin
Angiostatin is a piece (a fragment) of a protein, plasminogen, used normally in blood clotting. This fragment is normally secreted by tumors. It appears to halt the process of developing new blood vessels (angiogenesis) which is necessary to tumor development. Angiostatin may, it is hoped, represent a prototype for a new class of agents with which to treat cancer.
