We set out to determine whether advanced epithelial ovarian cancer (EOC) is associated with elevated serum and ascitic concentrations of the angiogenic factors angiogenin (ANG), basic fibroblastic growth factor (bFGF), and vascular endothelial growth factor (VEGF), and whether the expression of angiogenic factors was associated with tumor vascularity. Serum and ascitic samples were collected fr...

The creation of new blood vessels from existing ones, which is a mechanism called "angiogenesis", is essential in cancer to supply cancerous growth. Moreover, the development and the progression of the tumor and its metastases are the result of an efficient vascular response. Cancer cells release and activate different angiogenic growth factors and their receptors in the tumor microenvironment ...

Infantile hemangioma (IH) is a benign vascular tumor with abnormal proliferation of endothelial cells and impaired architecture. It believed that the pathogenesis IH based on angiogenesis impairment caused by imbalance between angiogenic anti-angiogenic factors. Despite spontaneous regression, which observed in 90% cases IH, several localizations may indicate possibility systemic manifestations...

Tumors of the central nervous system (CNS) often have sustained expression of labile genes, including angiogenic growth factors and immunosuppressive cytokines, which promote tumor progression. Stabilization of the RNA transcripts for these genes, such as vascular endothelial growth factor (VEGF), is an important molecular pathway for this up-regulation. HuR, a member of the Elav family of RNA-...

Although the function of vascular endothelial growth factor in the induction of tumor angiogenesis is well understood, the role of a second group of angiogenic factors, the fibroblast growth factors (FGFs), remains elusive. We used a recombinant adenovirus expressing soluble FGF receptor (AdsFGFR) to interfere with FGF function in tumor angiogenesis. AdsFGFR repressed endothelial cell prolifera...

Neovascularization is essential to the process of development and differentiation of tissues in the vertebrate embryo, and is also involved in a wide variety of physiological and pathological conditions in adults, including wound repair, metabolic diseases, inflammation, cardiovascular disorders, and tumor progression. Thanks to cumulative studies on vasculature, new therapeutic approaches have...

Anti-angiogenesis is the therapeutic strategy designed to disrupt vascular supply and starve tumors of nutrients oxygen. This achieved mainly by blocking endothelial growth factor (VEGF) actions, as VEGF signaling pathway considered main angiogenesis promoter active in tumor microenvironment (TME) under hypoxic conditions. A total 16 anti-angiogenic agents, including anti-VEGF antibodies, recep...

The concept of targeting tumor blood vessel formation, i.e. tumor angiogenesis, has long been accepted as a potential strategy for controlling tumor growth. Characterized by the ability to supply oxygen, growth factors, hormones and nutrients, tumor vasculature has been identified as a key factor for the maintenance and progression of many solid tumors. The development of tumor vasculature is r...
