Endostatin has ATPase activity, which mediates its antiangiogenic and antitumor activities.

Endostatin is an endogenous angiogenesis inhibitor with broad-spectrum antitumor activities. Although the molecular mechanisms of endostatin have been extensively explored, the intrinsic biochemical characteristics of endostatin are not completely understood. Here, we revealed for the first time that endostatin embedded novel ATPase activity. Moreover, mutagenesis study showed that the ATPase a...

E-M, an Engineered Endostatin with High ATPase Activity, Inhibits the Recruitment and Alternative Activation of Macrophages in Non-small Cell Lung Cancer

Endostatin recently was reported by our laboratory to possess ATPase activity that is indispensable for its anti-angiogenesis and anti-tumor effects. An engineered endostatin, E-M, which owns higher ATPase activity exhibits stronger inhibitory effects on angiogenesis. Tumor-associated macrophages (TAMs), especially M2-polarized TAMs, contribute to tumor progression by promoting tumor cell proli...

HEMOSTASIS, THROMBOSIS, AND VASCULAR BIOLOGY Nucleolin is a receptor that mediates antiangiogenic and antitumor activity of endostatin

The exact molecular mechanism of how endostatin inhibits angiogenesis and tumor growth remains uncharacterized. Here, we report that endostatin specifically binds to the cell surface nucleolin with high affinity. Blockage of nucleolin by a neutralizing antibody or knockdown of nucleolin by the RNA interference results in loss of antiendothelial activities of endostatin. Importantly, a neutraliz...

Extension of the in vivo half-life of endostatin and its improved anti-tumor activities upon fusion to a humanized antibody against tumor-associated glycoprotein 72 in a mouse model of human colorectal carcinoma

Endostatin is an endogenous angiogenesis inhibitor that exhibits potential anti-tumor efficacy in various preclinical animal models. However, its relatively short in vivo half-life and the long-term, frequent administration of high doses limit its widespread clinical use. In this study, we evaluated whether a fusion protein of murine endostatin (mEndo) to a humanized antibody against tumor-asso...
