Angiogenesis is an important mediator of tumor progression. As tumors expand, diffusion distances from the existing vascular supply increases, resulting in hypoxia in the cancer cells. Sustained expansion of a tumor mass requires new blood vessel formation to provide rapidly proliferating tumor cells with an adequate supply of oxygen and nutrients. The key(More)
In order to investigate the anti-angiogenic activity of shark TIMP-3 (sTIMP-3) in endothelial cells, angiogenic assays including in vitro invasion assay, migration assay, zymogram assay and tube formation assay were performed. We observed that the overexpression of sTIMP-3 decreased the invasive capacity by about 70%, the migratory activity by about 50% and(More)
Mitochondrial dysfunction has been found to be associated with various pathological conditions, particularly cancer. However, the mechanisms underlying tumor malignancy induced by mitochondrial dysfunction are not fully understood. In the present study, the effects of mitochondrial dysfunction on epithelial-mesenchymal transition (EMT), were investigated(More)
Angiogenesis is considered to be an integral process to the growth and spread of solid tumors. Anti-angiogenesis therapy recently has been found to be one of the most promising anti-cancer therapeutic strategies. In this study, we provide several lines of evidences showing that KR-31831, a new benzopyran derivative, has anti-angiogenic activities. KR-31831(More)
Ethyl pyruvate (EP), simple derivative of pyruvate, has been shown to have anti-inflammatory properties. Here, we demonstrate EP's strong anti-angiogenic activity. EP inhibited in vivo angiogenesis in the mouse Matrigel-plug assay and tumor growth in the mouse Lewis lung carcinoma model. EP also interfered with the angiogenic cascade, including growth,(More)
Angiogenesis is defined as the formation of new blood vessels form existing vessels surrounding a tumor. The process of angiogenesis is an important step for tumor growth and metastasis, as is inflammation. Thus, angiogenesis inhibitors that suppress inflammation have been studied as an anticancer treatment. Recently,(More)
A new piperazine derivative, SJ-8026, is a synthetic anti-cancer agent which exhibits topoisomerase II-inhibiting activities. In this study, we investigated the possibility that this compound inhibits angiogenesis and induces tumor-cell apoptosis using bovine aortic endothelial cells (BAECs) and human hepatocellular carcinoma cells (HepG2) as a model(More)
A new piperazine derivative, SJ-8002, is a synthetic anti-cancer agent which exhibits microtubule-inhibiting activities. In this study, we investigated the possibility that this compound inhibits angiogenesis and induces tumor-cell apoptosis using bovine aortic endothelial cells (BAECs) and human hepatocellular carcinoma cells (HepG2) as a model system,(More)
Coenzyme Q10 (CoQ10) is an essential factor of the mitochondrial respiratory chain and has effective antioxidant properties. Therefore, CoQ10 has been used in a variety of clinical applications and used as a nutritional supplement to treat several human diseases. Here, we tested the effects of CoQ10 on angiogenesis stimulated by basic fibroblast growth(More)
Angiogenesis is an important process involved in tumor growth and metastasis. Many studies have investigated the use of natural compounds such as angiogenic inhibitors. Xylitol is a 5-carbon sugar alcohol and is an artificial sweetener that has been used in chewing gums to prevent tooth decay. Xylitol has been also known to inhibit inflammatory cytokine(More)
