BACKGROUND Galectin-9 (Gal-9) is a mammalian lectin secreted by endothelial cells that is highly expressed in rheumatoid arthritis synovial tissues and synovial fluid. Roles have been proposed for galectins in the regulation of inflammation and angiogenesis. Therefore, we examined the contribution of Gal-9 to angiogenesis and inflammation in arthritis. METHODS To determine the role of Gal-9 i...

BACKGROUND: There is extraordinary interest in developing angiosuppressive agents for cancer treatment. Several new agents appear promising for the treatment of a variety of human cancers. Current concepts and new agents in clinical trials are the focus of this article. In particular, the introduction of a new treatment for human brain tumors is presented in detail, using an antiangiogenic agen...

A practical and modular approach to obtain a diverse set of 14-membered macrocyclic compounds from carbohydrates is developed that utilizes functional groups at C-1 and C-5. The evaluation of this toolbox in various zebrafish assays led to the identification of 2.7f as an antiangiogenesis agent.

Like other previous treatments and approaches, sorafenib, an antiangiogenic drug, failed to show any benefit in the adjuvant setting for hepatocellular carcinoma in a large clinical trial. We discuss reasons and implications of these negative results and the implications for clinical practice and future research. TRIAL REGISTRATION ClinicalTrials.gov: NCT00692770 . Registered 5 June 2008. Thi...

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...

Angiogenesis, or the growth of new blood vessels from existing vasculature, is critical for the proper development of many organs. This process is inhibited and tightly regulated in adults, once endothelial cells have acquired organ-specific properties. Within the central nervous system (CNS), angiogenesis and acquisition of blood-brain barrier (BBB) properties by endothelial cells is essential...

Chromatin remodeling agents such as histone deacetylase inhibitors have been shown to modulate gene expression in tumor cells and inhibit tumor growth and angiogenesis. Vascular endothelial growth factor (VEGF) and VEGF receptors represent critical molecular targets for antiangiogenesis therapy. In this study, we investigated the biological effect of the histone deacetylase inhibitor NVP-LAQ824...
