Regulation of angiogenesis by endothelial metabolism

 

Research in the Potente laboratory is focused on blood vessels, particularly the regulation of blood vessel growth (angiogenesis) by metabolism. Angiogenesis and metabolism are tightly coupled as blood vessels supply nutrients and oxygen to energy-consuming tissues. We study how endothelial cells, which line the inner surface of blood vessels, sense and respond to metabolic signals and how they use this information to build vascular networks of organ-specific size, shape, and function. We are also interested in the metabolism of endothelial cells, aiming to understand how endothelial metabolic state can exert control over genetically hard-wired signals. We believe that a detailed understanding of endothelial metabolism will provide new perspectives on disease mechanisms in the vascular system with implications for disorders with aberrant vessel growth such as cancer.
