BACKGROUND WA-25 (dihydroaustrasulfone alcohol, a synthetic derivative of marine compound WE-2) suppresses atherosclerosis in rats by reducing neointima formation. Because angiogenesis plays a critical role in the pathogenesis of atherosclerosis, the present study investigated the angiogenic function and mechanism of WA-25. METHODS The angiogenic effect(More)
Celecoxib, a COX-2 inhibitor and non-steroidal anti-inflammatory drug, can prevent several types of cancer, including hepatocellular carcinoma (HCC). Here we show that celecoxib suppressed the self-renewal and drug-pumping functions in HCC cells. Besides, celecoxib depleted CD44+/CD133+ hepatic cancer stem cells (hCSC). Prostaglandin E2 (PGE2) and CD133(More)
PURPOSE Choroidal neovascularization (CNV) is the leading cause of blindness in patients with age-related macular degeneration (AMD). This study evaluated the inhibitory effect of vasostatin (VS), an endogenous angiogenesis inhibitor, on CNV. METHODS Anti-angiogenic activity of VS was evaluated in vitro by migration and tube formation assays in human(More)
Hepatoma-derived growth factor (HDGF) stimulates the migration, invasion and metastasis in several types of cancer cells. However, the mechanism underlying HDGF-stimulated migration remains unclear. In this study, we investigated the influence of HDGF on cytoskeleton remodeling and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway in(More)
Angiogenesis, the process of neovascularization, plays an important role in physiological and pathological conditions. ST104P is a soluble polysulfated-cyclo-tetrachromotropylene compound with anti-viral and anti-thrombotic activities. However, the functions of ST104P in angiogenesis have never been explored. In this study, we investigated the effects of(More)
PURPOSE Vasostatin 48 (VS48) is a peptide of 48 amino acids derived from calreticulin. This study aimed to investigate the effects of topical application of VS48 eyedrops on experimental choroidal neovascularization (CNV). METHODS Recombinant VS48 was expressed and purified as a thioredoxin (TRX)-fused protein, TRX-VS48. The anti-angiogenic effects of(More)
BACKGROUND Gene therapy of proopiomelanocortin, the precursor of α-melanocyte-stimulating hormone (α-MSH), suppresses the neovascularization in tumors. However, the roles of α-MSH in angiogenesis remain unclear. METHODS The influence of α-MSH on angiogenesis was evaluated by ex vivo rat aorta and in vivo, including transgenic zebrafish and chicken(More)
Dialysis-related amyloidosis (DRA), caused by the accumulation of beta-2-microglobulin (β-2M), remains a major concern in long-term renal replacement therapies. For years, we have developed an immunoadsorption wall (iWall) for the removal of β-2M. In this study, we employed a new approach taking advantage of the melting of a buffer ice rod to improve the(More)
