PLASMINOGEN KRINGLE 4 REGION FRAGMENTS AND METHODS OF USE

摘要

Fragments of an endothelial cell proliferation inhibitor and method of use therefor are provided. The endothelial proliferation inhibitor is a protein derived from plasminogen, or more specifically is an angiostatin kringle 4 region fragment. The kringle 4 region fragments generally correspond to kringle 4 structures occurring within the endothelial cell proliferation inhibitor. The endothelial cell inhibiting activity of these fragments provides a means for inhibiting angiogenesis of tumors and for treating angiogenic-mediated disease.
