Abstract: Extracellular matrix remodelling is a prerequisite for plaque rupture in atherosclerotic lesion. Versican, an extracellular matrix
proteoglycan present in normal and atherosclerotic arteries is a substrate for matrix metalloproteinases (MMPs) present in
macrophage rich areas. The aim of the current study was to develop an immunoassay to detect a specific MMP-12 derived versican
degradation fragment (VCANM) and assess its potential as a biomarker for extracellular matrix remodelling in atherosclerosis. A
mouse monoclonal antibody raised against VCANM was used for the development of a competitive ELISA for detection of the fragment
in plasma. VCANM was measured in plasma of patients with different levels of heart diseases. Patients experiencing I) acute coronary
syndrome, II) stable ischemic heart disease and III) demonstrating high levels of coronary calcium deposits had significantly higher
plasma levels of VCANM compared to a control group of individuals with no detectable coronary calcium deposits. VCANM was also
detected by immunohistochemistry in coronary artery sections of patients with different degrees of atherosclerosis. VCANM ability to
separate patients with atherosclerotic diseases from healthy individuals suggested VCANM as a potential biomarker for the
pathological arterial matrix remodelling associated with atherosclerosis. (IJCEM1302003).
