  • Patent number: 8426376
    Abstract: Because AK022567 has angiogenesis inhibitory activity, it is useful as an angiogenesis inhibitor. Furthermore, 4 splicing variants obtained from the same gene are also useful as an angiogenesis inhibitor. These 5 polypeptides, polynucleotides encoding the polypeptides and antibodies against the polypeptides are useful for screening of a candidate compound as an angiogenesis inhibitor or promoter. A compound obtained from the screening is useful as a medicine and can be used for a preventive or therapeutic agent for an angiogenesis related disease.

  • Publication number: 20090270314
    Abstract: 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.
