Angiostatin, a recently discovered anti-angiogenic factor, offers the hope of long-term control of metastatic cancers following surgery.

introduction: breast cancer is one of the provalent cancers in the world. this cancer as well as other solid tumors, in the course of its development has phases in this order: epithelial dysplasia, carcinoma insitu, invassiveness and metastasis. breast cancer diagnosis is generally made with pathology methods. in this survey, measuring angiostatin (which is one of the most important and potent...

Exposure to hypoxia leads to the development of pulmonary hypertension (PH) as a consequence of pulmonary smooth muscle hyperplasia. Hypoxia concomitantly stimulates lung expression of angiogenic factors. To investigate the role of angiogenesis processes in development of hypoxic PH, we examined the effects of lung overexpression of angiostatin, an angiogenesis inhibitor, on development of hypo...

It is known that benign breast tissue exhibit relatively low angiogenic capacity. Activation of angiogenesis in mammary pre-malignant lesions could be associated with disease progression and high risk of transformation into the breast cancer. However, insight into the underlying molecular mechanisms involved in angiogenesis regulation in non-cancerous breast pathologies is still poorly defined....

BACKGROUND Development of coronary collateral vessels is impaired in patients with diabetes mellitus. We tested the hypothesis that hyperglycemia alone attenuates collateral development and abolishes proliferative properties of myocardial interstitial fluid (MIF) by enhancing expression of matrix metalloproteinases (MMP) and angiostatin. METHODS AND RESULTS Chronically instrumented dogs were ...

Gene therapy transfer of angiostatin and endostatin represents an alternative method of delivering angiogenic polypeptide inhibitors. We examined whether liposomes complexed to plasmids encoding angiostatin or endostatin inhibited angiogenesis and the growth of MDA-MB-435 tumors implanted in the mammary fat pads of nude mice. We determined that plasmids expressing angiostatin (PCI-Angio) or end...

Antiangiogenic therapy is a promising alternative for prostate cancer growth and metastasis and holds great promise as an adjuvant therapy. The present study evaluated the potential of stable expression of angiostatin and endostatin before the onset of neoplasia and during the early and late stages of prostate cancer progression in transgenic adenocarcinoma of mouse prostate (TRAMP) mice. Group...

Malignant cancers commonly invade locally followed by spread through venous or lymphatic channels or both to distant sites. Hemangiogenesis and its relation to tumor growth and metastasis have been extensively studied. However, the role played by lymphangiogenesis in growth and metastasis of cancer has been largely neglected until just recently. Inhibition of lymphangiogenesis, as compared to i...
