Background: Bioactive compounds such as terpenoids, chondroitin sulfate, and polysaccharides with added value can be found in prestine marine creatures. These compounds often do have highly valuable therapeutic applications such as being antioxidant, antitumorogenic, anti-infl ammatory and anti-angiogenic. For the latter, varieties of angiogenesis factors can suppress this issu...

Angiogenesis means the formation of new blood vessels from preexisting vascular, is of fundamental importance in several pathological states such as tumor growth, rheumatoid arthritis, and diabetic retinopathy. Angiogenesis involves a set of steps, including activation and movement of endothelial cells and tube formation. Control of these steps by drugs or dietary food components is a hopeful a...

BACKGROUND Anti-angiogenic therapy in certain cancers has been associated with improved control of tumor growth and metastasis. Development of anti-angiogenic agents has, however, been saddled with higher attrition rate due to suboptimal efficacy, narrow therapeutic windows, or development of organ-specific toxicities. The aim of this study was to evaluate the translational ability of the zebra...

Angiogenesis, that is the construction of new vessels from pre-existing vessels, is a crucial event in not only physiological but also pathological conditions; for example, wound healing and the female reproductive cycle are related to it in a physiological condition. On the other hand, diabetic retinopathy and chronic inflammation are closely involved in pathological angiogenesis. In particula...

objective(s): herbal medicines are promising cancer preventive candidates. it has been shown that punica granatum l. could inhibit angiogenesis and tumor invasion. in this study, we investigated whether the anti-angiogenic effect of pomegranate peel extract (ppe) is partly attributable to peroxisome proliferator-activated receptors (ppars) activation in the human umbilical vein endothelial cell...

this study aimed to investigate the anti-angiogenic activity of vitex agnus castus methanol extract in vivo. eggs were incubated for three days, small whole made on the fine pinpoint, next day the egg’s sac penetrated and a small frame was made in the shell. the window was resealed and eggs were returned to the incubator until day 10 of chick embryo development, 20 µl of 500mg/ml of the methano...

A number of anti-angiogenesis drugs have been FDA-approved and are being used in cancer treatment, and a number of other agents are in different stages of clinical development or in preclinical evaluation. However, pharmacologic anti-angiogenesis strategies that arrest tumor progression might not be enough to eradicate tumors. Decreased anti-angiogenesis activity in single mechanism-based anti-...

Although it has been known that the tumor microenvironment affects angiogenesis, the precise mechanism remains unclear. In this study, we simulated the microenvironment of human esophageal squamous cell carcinoma (ESCC) by tumor conditioned medium (TCM) to assess the influence on normal endothelial cells (NECs). We found that the TCM-induced NECs showed enhanced angiogenic properties, such as m...
