Also known as VEGF-A or VEGF isoform 165 this protein has a mass of around 23 kDa when it is in its biotinylated form. VEGF 165A is expressed in various cell types including endothelial cells which form the lining of blood vessels as well as in smooth muscle cells and certain tumor cells. The protein is often targeted in research using anti-VEGF antibodies.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThis protein acts directly on endothelial cells to stimulate their proliferation and migration. VEGF 165A is part of a larger family of VEGF proteins that share similar structures and functions. It plays a critical role in both physiological processes like wound healing and pathological conditions like cancer where its expression becomes dysregulated. The protein can bind to receptors on the cell surface initiating cell signaling pathways that lead to angiogenesis.\u003cbr\u003e\nPathways\u003cbr\u003e\nVEGF 165A functions prominently in the VEGF signaling pathway and the MAPK\/ERK pathway. Through these pathways it interacts with other proteins such as VEGF receptors particularly VEGFR-2 to propagate signals leading to angiogenesis and increased vascular permeability. These pathways are vital in ensuring that tissues receive an appropriate blood supply under various conditions including growth and repair processes.\u003cbr\u003e\nVEGF 165A shows an association with cancer and age-related macular degeneration (AMD). Overexpression of VEGF 165A is linked to tumor growth because it helps form the blood vessels that supply the tumor known as tumor angiogenesis. Similarly in AMD abnormal blood vessel growth driven by VEGF 165A leads to damage in the retina. Anti-VEGF therapies often target this protein to treat these conditions by inhibiting its action on blood vessel formation.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843807793321,"sku":"ab259412","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab259412","provider":"Iright","version":"1.0","type":"link"}
