Fibulin-1 is the first described member of a seven-gene family of extracellular matrix (ECM) proteins that have a common structural signature consisting of a series of repeated EGF-like domains followed by a fibulin-type module at its carboxyl terminus (1, 2). Fibulin-1 is a secreted glycoprotein that is an intercellular component of a wide range of connective tissues (3, 4). In blood vessel walls, fibulin-1 is a component of elastic lamina and ECM fibers that surround smooth muscle cells and underlie the endothelium. Although its actual function remains to be elucidated, fibulin-1 has been suggested to be involved in cell adhesion, migration, proliferation, and malignant transformation through binding to many ECM proteins, including laminin, fibrinogen, fibronectin, nidogen-1, endostatin, β-amyloid precursor protein and proteoglycans, aggrecan, versican (5-11), receptors and growth factors (12, 13). In addition, fibulin-1 has been found to bind to the plasma protein fibrinogen and to incorporate into fibrin clots formed in vitro and in vivo (14). Targeted inactivation of fibulin-1 gene in mice caused dilation and ruptures in the endothelial lining of small blood vessels (15), indicating that fibulin-1 was important in the stabilization of blood vessel walls. Fibulin-1 is one of a few ECM proteins normally found in blood in high concentrations (16). It was reported that plasma fibulin-1 concentrations increased in T2DM patients with prevalent cardiovascular disease destined for vascular surgery (17) as well as in asthmatics (18).
