Publication number: 20090270314Abstract: The present inventors found out four kinds of fragments (42 kD, 36 kD, 32 kD, 27 kD) by forcibly expressing vasohibin in a vascular endothelial cell. The present inventors analyzed those fragments and, as a result, found out low molecular weight vasohibin which has an anti-angiogenic activity. The low molecular weight vasohibin is useful as a therapeutic agent for various diseases such as a vascular disease associated with angiogenesis, an inflammatory disease, an entoptic neovascular disease, a reproductive disease, a central nervous system disease and cancer and the like. In addition, the low molecular weight vasohibin is also useful as a marker for angiogenesis.Type: ApplicationFiled: September 27, 2006Publication date: October 29, 2009Applicant: TOHOKU UNIVERSITYInventors: Yasufumi Sato, Hikaru Sonoda, Hideki Ohta
