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...
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 plays a key role in tumor growth and cancer progression. TIE-2-expressing monocytes (TEM) have been reported to critically account for tumor vascularization and growth in mouse tumor experimental models, but the molecular basis of their pro-angiogenic activity are largely unknown. Moreover, differences in the pro-angiogenic activity between blood circulating and tumor infiltrated T...
background and objectives: retinoblastoma is the most common intraocular pediatric malignancy. angiogenic factor expression such as vegf (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. this study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ survival. mater...
A shift of the angiogenic balance to the proangiogenic state, termed the "angiogenic switch," is a hallmark of cancer progression. Here we devise a strategy for identifying genetic participants of the angiogenic switch based on inverse regulation of genes in human endothelial cells in response to key endogenous pro- and antiangiogenic proteins. This approach reveals a global network pattern for...
PURPOSE The present study considered the hypothesis that spontaneous neovascularization of the cornea of nude mice results from a local imbalance between angiogenic and anti-angiogenic factors. METHODS The presence of angiogenic and anti-angiogenic factors was revealed by exchanging orthotopic corneal allografts between nude BALB/c mice and normal (hirsute) euthymic BALB/c mice and observing ...
As hypoxia-induced inflammatory angiogenesis may contribute to the manifestations of sickle cell disease, we compared the angiogenic molecular profiles of plasma from sickle cell disease individuals and correlated these with in vitro endothelial cell-mediated angiogenesis-stimulating activity and in vivo neovascularization. Bioplex demonstrated that plasma from patients with steady-state sickle...
UNLABELLED The angiogenic switch, a rate-limiting step in tumor progression, has already occurred by the time most human tumors are detectable. However, despite significant study of the mechanisms controlling this switch, the kinetics and reversibility of the process have not been explored. The stability of the angiogenic phenotype was examined using an established human liposarcoma xenograft m...
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...
Malignant gliomas (glioblastoma multiforme) have a poor prognosis with an average patient survival under current treatment regimens ranging between 12 and 14 months. The tumors are characterized by rapid cell growth, extensive neovascularization, and diffuse cellular infiltration of normal brain structures. We have developed a human glioblastoma xenograft model in nude rats that is characterize...
