Human Vascular Endothelial Growth Factor A (VEGFA) Protein

Background

VEGFA is a key member of the vascular endothelial growth factor (VEGF) family and plays a crucial role in angiogenesis, vascular permeability, and endothelial cell proliferation VEGFA binds primarily to its receptors VEGFR-1 and VEGFR-2, triggering signaling pathways like PI3K/AKT and ERK/MAPK to promote blood vessel formation during embryonic development, wound healing, and tissue repair Dysregulated VEGFA expression is associated with pathological angiogenesis observed in cancer, diabetic retinopathy, and age-related macular degeneration (AMD) VEGFA also increases vascular permeability by altering endothelial junctions, contributing to fluid leakage in conditions such as inflammation and tumors Targeted therapies, such as bevacizumab and other anti-VEGF agents, inhibit VEGFA activity to suppress angiogenesis and tumor growth in various cancers and ocular diseases
