Angiogenesis is the formation of new blood vessels form pre-existing vasculature whose contribution to inflammatory conditions of the Central Nervous System is being studied in order to generate novel therapeutic targets. This study is the first to investigate the impact of two particular angiogenesis inhibitors on murine Experimental Autoimmune Encephalomyelitis (EAE), an inflammatory disease ...

For many men, prostate cancer is an indolent disease that, even without definitive therapy, may have no impact on their quality of life or overall survival. However for those men who are either diagnosed with or eventually develop metastatic disease, prostate cancer is a painful and universally fatal disease. Testosterone-lowering hormonal therapy may control the disease for some time, but pati...

Tumor angiogenesis requires intricate regulation of gene expression in endothelial cells. We recently showed that DNA methyltransferase (DNMT) and histone deacetylase (HDAC) inhibitors directly repress endothelial cell growth and tumor angiogenesis, suggesting that epigenetic modifications mediated by DNMTs and HDAC are involved in regulation of endothelial cell gene expression during tumor ang...

Fractalkine (FKN) has been implicated in modulation of angiogenesis and vascular inflammation, but the underlying mechanism has not been elucidated. We have investigated the molecular mechanism by which FKN regulates angiogenesis. We found that recombinant FKN increases in vitro proliferation, migration, and tube formation of human umbilical vein endothelial cells and stimulates in vivo angioge...

Inhibition of angiogenesis is an effective and low toxic therapeutic avenue for the treatment of cancer patients in addition to traditional interventions. Majority of current available angiogenesis inhibitors for cancer therapies are growth factor inhibitors and small molecule tyrosine kinase inhibitors. A number of endogenous proteins and/or proteolytic fragments of extracellular matrix protei...

An association between platelets, angiogenesis, and cancer has long been recognized, but the mechanisms linking them remains unclear. Platelets regulate new blood vessel growth through numerous stimulators and inhibitors of angiogenesis by several pathways, including differential exocytosis of angiogenesis regulators. Herein, we investigated the differential release of angiogenesis stimulators ...

Angiogenesis inhibitors have evolved as a new diverse class of compounds that can be used to block tumor growth (1,2). The inhibitors, which may be natural or synthetic, include protease inhibitors (i.e., tissue inhibitors of matrix metalloproteinases), tyrosine kinase inhibitors, chemokines, interleukins, and proteolytic fragments of diverse molecules (i.e., endostatin, vasostatin, canstatin, ...

Platelets promote angiogenesis by releasing angiogenesis-regulating factors from their α-granules upon aggregation. This effect has both physiologic and pathologic significance as it may contribute to carcinogenesis. Platelet α-granule release and aggregation are regulated, in part, via protein kinase C (PKC) α and β signaling. Our study investigated the effects of PKC inhibition on aggregation...

One critical event of tumour invasion that signals the initiation of the metastatic cascade is thought to be interaction of the tumour cell with the basement membrane. Basement membranes may also pose as barriers to tumour cell invasion at multiple points later in the metastatic cascade, including during the processes of vascular infiltration and extravasation. Thus, an important proteolytic ev...

Angiogenesis is a complex multi-process involving various activities of endothelial cells. These activities are influenced in vivo by environmental conditions like interactions with other cell types and the microenvironment. Galectins play a role in several of these interactions and are therefore required for proper execution of in vivo angiogenesis. In this chapter we describe a method to stud...
