Angiogenesis as a new target for cancer treatment
1Department of Biochemistry, Kyushu University School of Medicine, Fukuoka, Japan.
Abstract:
Neovascularization is often required for rapid growth of solid tumors and also limits vascular metastasis of tumor cells. Neovascularization-targeting agents are a recent innovation that may be a novel means of anticancer therapy. These antiangiogenic drugs have been developed by targeting cell proliferation of vascular endothelial cells, basement-membrane-degrading enzymes, angiogenic factors/receptors, extracellular matrix, angiogenesis signaling, and cell-cell/cell-matrix interactions. In this report, we describe how tumor angiogenesis occurs and how antiangiogenic agents are developed.
Insights
Tumor growth and metastasis depend on new blood vessel formation (neovascularization). Antiangiogenic drugs target this process, offering a novel approach to cancer therapy by inhibiting tumor angiogenesis.
