Vascular endothelial growth factor (VEGF), a potent angiogenic mitogen, plays a crucial role in angiogenesis under various pathophysiological conditions. We have recently demonstrated that VEGF(165), one of the VEGF isoforms, binds connective tissue growth factor (CTGF) and that its angiogenic activity is inhibited in the VEGF(165).CTGF complex form (Inoki, I., Shiomi, T., Hashimoto, G., Enomot...

Synadenium umbellatum Pax, popularly known as 'cola-nota', is a medicinal plant that grows in tropical regions. Latex of this plant is used to treat various diseases such as diabetes mellitus, Hansen s disease, tripanosomiases, leukemia and several malignant tumors. In the present study, the angiogenic activity of S. umbellatum latex was evaluated using the chick embryo chorioallantoic membrane...

To search for novel compounds with potent anti-angiogenic activity, a series of N(1)-(substituted benzyl)-3-(4-methylphenyl)-1H-indazoles (16, 18, 20, 22, 24, 26, 28, 30, 32) and N(2)-(substituted benzyl)-3-(4-methylphenyl)-2H-indazoles (17, 19, 21, 23, 25, 27, 29, 31, and 33) were synthesized. The structures of these regioisomers were established by IR, UV, and NMR spectral data. 3-(4-Methylph...

Background: Anti-angiogenic therapy is a crucial step in cancer treatment. The discovery of new anti-angiogenic compounds from marine organisms has become an attractive concept in anti-cancer therapy. Because little data correlated to the pro- and anti-angiogenic efficacies of Ophiuroidea, which include brittle star, the current study was designed to explore the anti-angiogenic potential of bri...

The process of angiogenesis consists in the sprouting of new blood vessels from existing ones. This is a natural process that occurs in the human body and is essential for organ growth and repair. In the embryonic stage, the blood vessels provide the necessary oxygen, nutrients and instructive trophic signals to promote organ morphogenesis (Coultas et al., 2005). After birth the angiogenic proc...

Hyaluronan (HA) is a high molecular weight linear glycosaminoglycan and abundant in the skin extracellular matrix. Cutaneous HA first depolymerized to intermediate sizes then further fragmented regional lymph nodes. High anti-inflammatory anti-angiogenic, whereas pro-inflammatory pro-angiogenic. We have reported that HYBID (HA-Binding protein Involved Depolymerization), also known as KIAA1199/C...

Angiogenesis, in particular anti-angiogenesis, is an area of particular therapeutic interest in cancer treatment. Several anti-angiogenic agents are in the final stages of clinical trials. One of these agents, thalidomide, best known for its teratogenic potential, is showing promise against several tumor types. Thalidomide has been shown previously to require bio-activation to exert its anti-an...

The effects of genistein on angiogenesis remain poorly understood. Some studies claim an antiangiogenic effect and others claim a pro-angiogenic one. Thus, the aim of this study was to determine if genistein may exhibit bivalent angiogenic effects. To address this question, genistein angiogenic modulatory effects were examined using an in vitro 3D angiogenesis model using human umbilical vein e...

OBJECTIVE Clinical symptoms and radiological changes are useful in monitoring patients with interstitial lung diseases (ILD). Neovascularization participates in the pathogenesis of idiopathic pulmonary fibrosis and other ILD. The objective of the study was to examine the relationships between angiogenic activity of sera from ILD patients and clinical or radiological status. MATERIAL AND METHO...

Previously, we identified DPTH, an analogue of antiepileptic drug phenytoin (5,5-diphenylhydantoin, DPT), capable of retarding the cell cycle in the human vascular endothelial cells. Our data suggest that DPTH inhibits human umbilical venous endothelial cells (HUVEC) proliferation by increasing the level of p21 protein, which in turn inhibits the activities of cyclin-dependent kinase (CDK)2 and...
