Scientists from the Gladstone Institute of Cardiovascular Disease (GICD) and UCSF have identified a key regulatory factor that controls development of the human vascular system, the extensive network of arteries, veins, and capillaries that allow blood to reach all tissues and organs.
The research, published in the latest issue of Developmental Cell, may offer clues to potential therapeutic targets for a wide variety of diseases, such as heart disease or cancer, that are impacted by or affect the vascular system.
Researchers in laboratory of GICD Director Deepak Srivastava, MD, found that microRNA (miR-126), a tiny RNA molecule, is intimately involved in the response of blood vessels to angiogenic signals. Angiogenesis, the process of vascular development, is a tightly regulated and well-studied process.A cascade of genes orchestrate a series of events leading to formation of blood vessels in an embryo.
