Girinimbine is a carbazole alkaloid isolated from the stem bark and root of Murraya koenigii. Here we report that girinimbine is an inhibitor of angiogenic activity both in vitro and in vivo. MTT results showed that girinimbine inhibited proliferation of human umbilical vein endothelial cells, while results from endothelial cell invasion, migration, tube formation, and wound healing assays demo...

Since angiogenesis is critical for tumor growth and metastasis, anti-angiogenic treatment is a highly promising therapeutic approach. Thus, for over last couple of decades, there has been a robust activity aimed towards the discovery of angiogenesis inhibitors. More than forty anti-angiogenic drugs are being tested in clinical trials all over the world. This review discusses agents that have ap...

Am J Physiol Heart Circ Physiol 292: H743–H750, 2007. First published October 27, 2006; doi:10.1152/ajpheart.00969.2006.—Pentosan polysulfate (PPS) is a heparin-like polysaccharide that can affect the binding interactions of ...

BACKGROUND Heparan sulfate (HS) is an important regulator of the assembly and activity of various angiogenic signalling complexes. However, the significance of precisely defined HS structures in regulating cytokine-dependent angiogenic cellular functions and signalling through receptors regulating angiogenic responses remains unclear. Understanding such structure-activity relationships is impor...

The angiogenesis activity was involved in many physiological and pathological conditions. The research on angiogenesis activity was increased and many new methods are come for the evaluation of the angiogenesis activity. Previously Robert Auerbach et al., described the methods used for the evaluation of angiogenesis activity. We added some more techniques to that which are currently used for th...

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...

PURPOSE Inhibition of neovessel development can stabilize tumor growth. A rapid in vitro method that can evaluate the effectiveness of anti-angiogenic drugs would aid in drug development. We tested a series of investigational agents to determine their ability to inhibit angiogenesis in our in vitro human angiogenesis model. METHODS A total of 74 neuroendocrine tumors were tested with five the...

BACKGROUND Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has the ability to inhibit angiogenesis by inducing endothelial cell death, as well as being able to promote pro-angiogenic activity in vitro. These seemingly opposite effects make its role in ischemic disease unclear. Using Trail(-/-) and wildtype mice, we sought to determine the role of TRAIL in angiogenesis and neovas...

The chorioallantoic membrane (CAM) is one of the most vascularized tissues in the chicken embryo. Capillary growth proceeds until day 10 of development and thereafter abruptly regresses. As it is generally accepted that the formation of new blood vessel is regulated by growth factors, we have investigated the presence of angiogenic and mitogenic factors in the chicken chorioallantois. In the pr...
