Biological or Clinical Significance:

Vascular endothelial growth factor A (VEGF-A) is a protein that in humans is encoded by the VEGFA gene. Vascular endothelial growth factor A (VEGF-A) is a dimeric glycoprotein that plays a significant role in neurons and is considered to be the main, dominant inducer to the growth of blood vessels. VEGFA is essential for adults during organ remodeling and diseases that involve blood vessels.

VEGF-A has been implicated with poor prognosis in breast cancer. VEGF-A is also released in rheumatoid arthritis in response to TNF-α, increasing endothelial permeability and swelling and also stimulating angiogenesis. VEGF-A is also important in diabetic retinopathy (DR). VEGF-A plays a role in the disease pathology of the wet form age-related macular degeneration (AMD), which is the leading cause of blindness for the elderly of the industrialized world. Once released, VEGF-A may elicit several responses. It may cause a cell to survive, move, or further differentiate. Hence, VEGF is a potential target for the treatment of cancer.
