Therapeutic angiogenesis remains unsuccessful in coronary artery disease. It is known that plasma endothelium-derived microparticles (EMPs) are increased in coronary artery disease and that hypercholesterolemia can inhibit angiogenesis. We evaluated the relationship between EMPs and hypercholesterolemia in the impairment of angiogenesis. EMPs isolated from human umbilical vein endothelial cells...
Background: 4-Aryl-4H-chromenes are novel anticancer agents which induce apoptosis in cancer cells. These compounds were found to induce apoptosis by targeting the tubulin/microtubule system in cell proliferation process. The aim of this study was to report cyototoxic and apoptosis inducing activities of a new series of synthesized 4-aryl-4H-chromenes compounds. Methods: The in vitro cytotoxic...
Angiopoietin-2 (ANG-2) is a key regulator of angiogenesis that exerts context-dependent effects on ECs. ANG-2 binds the endothelial-specific receptor tyrosine kinase 2 (TIE2) and acts as a negative regulator of ANG-1/TIE2 signaling during angiogenesis, thereby controlling the responsiveness of ECs to exogenous cytokines. Recent data from tumors indicate that under certain conditions ANG-2 can a...
Mitogen-activated protein kinase kinase kinase 3 (MEKK3) plays an essential role in embryonic angiogenesis, but its role in tumor growth and angiogenesis is unknown. In this study, we further investigated the role of MEKK3 in embryonic angiogenesis, tumor angiogenesis, and angiogenic factor production. We found that endothelial cells from Mekk3-deficient embryos showed defects in cell prolifera...
BACKGROUND Angiogenesis is a critical component of tumor development and proliferation, and increased angiogenesis has been associated with a worse clinical outcome in a number of solid tumors, including ovarian cancer. Therefore, agents that target the angiogenic process are of considerable interest in the treatment of ovarian cancer. METHODS Studies evaluating the efficacy of antiangiogenic...
Breast cancer is one of the leading causes cancer-related death in women. Currently, treatment breast limited by lack effectively targeted therapy and patients often suffer from higher severity, metastasis, resistance. Extracellular vesicles (EVs) consist lipid bilayers that encapsulate a complex cargo, including proteins, nucleic acids, metabolites. These bioactive cargoes have been found to p...
Angiogenesis is required for tumor growth and metastasis and, therefore, represents an exciting target for cancer treatment. Angiogenesis is a complex process that is tightly regulated by pro- and anti-angiogenic growth factors. Physiologic angiogenesis takes place during tissue growth and repair, during the female reproductive cycle, and during fetal development. Pathologic angiogenesis is cha...
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...
Abstract Our previous studies showed that various extracts of Persian shallot (Allium hirtifolium) have anti-angiogenic effects. This study has been undertaken to isolate and identify the major effective anti-angiogeneic sub-fraction of shallot. After preparation of the 50% hydroalcoholic extract of shallot bulbs, the extract was successively fractionated into n-hexane, ethyl acetate, n-butanol...
In 1971, Judah Folkman published in the “New England Journal of Medicine” a hypothesis that tumor growth is angiogenesis-dependent and that inhibition of angiogenesis could be therapeutic [1]. This article also introduced the term antiangiogenesis to mean the prevention of new vessel sprouts from being recruited by a tumor. In the last 35 years, it has been estimated that > 200 companies have w...
