Resection of primary tumors is often followed by accelerated growth of metastases. Here we propose that this effect may be due to the fact that resection of primary tumor results in a decrease in the total systemic amount of angiogenesis stimulators, such as VEGF and bFGF. This in turn causes decrease in the systemic level of angiogenesis inhibitors, such as PF-4 and TSP-1, which at least tempo...
Rheumatoid arthritis (RA) is characterised by synovial tissue leucocyte ingress and angiogenesis, or new blood vessel growth. The disease is thought to occur as an immunological response to an as yet unidentified antigen. Even in early RA, some of the earliest histological observations are blood vessels. A mononuclear infiltrate characterises the synovial tissue along with a luxuriant vasculatu...
Uncontrolled neovascularization occurs in several angiogenesis-dependent diseases, including cancer. Neovascularization is tightly controlled by the balance between angiogenic growth factors and antiangiogenic agents. The various natural angiogenesis inhibitors identified so far affect neovascularization by different mechanisms of action. Thrombospondin-1 (TSP-1) is a matricellular modular glyc...
Angiogenesis and vasculogenesis constitute two processes in the formation of new blood vessels and are essential for progression of solid tumors. Consequently, targeting angiogenesis, and to a lesser extent vasculogenesis, has become a major focus in cancer drug development. Angiogenesis inhibitors are now being tested in pediatric populations whereas inhibitors of vasculogenesis are in an earl...
The developed standardized human cell based in vitro angiogenesis assay was intra-laboratory pre-validated to verify that the method is reliable and relevant for routine testing of modulators of angiogenesis, e.g., pharmaceuticals and industrial chemicals. This assay is based on the earlier published method but it was improved and shown to be more sensitive and rapid than the previous assay. Th...
Angiogenesis is defined as a new blood vessel sprouting from pre-existing vessels. This highly regulated process take place through two non-exclusive events, the so-called endothelial sprouting or non-sprouting (intussusceptive) microvascular growth. This review article will provide a brief overview of some relevant topics defining sprouting angiogenesis and including: (i) The concept of functi...
Metronomic chemotherapy with cytotoxic agents has been shown to inhibit angiogenesis and, consequently, tumor growth by targeting vascular endothelial cells (ECs). In these regimens, anti-tumor activities additional to anti-angiogenesis may operate. Moreover, chemotherapy typically generates reactive oxygen species in targeted ECs, which can affect angiogenesis. The aim of the present study was...
Over the last several decades, oncology research and cancer treatment have concentrated primarily on the cancer cells. Unfortunately, despite the intensive quest to find new and more effective compounds for chemotherapy, the survival rate of patients has not significantly changed. In 1971 Judah Folkman proposed that a solid tumor cannot grow without inducing angiogenesis. Intensive search for m...
Amelogenin directly binds to glucose-regulated protein 78 (Grp78). Cell migration activity is expected increase when human periodontal ligament cells (hPDLCs) overexpressing Grp78 are treated with amelogenin. Geranylgeranylacetone (GGA) a drug that induces the expression of heat shock and routinely used treat gastric ulcers. Here, we investigated changes in properties behavior hPDLCs response t...
