Endocrine Gland-Derived Vascular Endothelial Growth Factor (EG-VEGF/PK-1) is a member of the prokineticin family of secreted proteins. It is expressed in various tissues including the GI tract and steroidogenic glands (1). EG-VEGF promotes angiogenesis acting via two G-protein coupled receptors, PK-R1 and PK-R2 (2). EG-VEGF results in the activation of MAPK p44/42 and phosphatidylinositol 3-kinase signaling pathways, leading to proliferation, migration, and survival of responsive endothelial cells (3).
