Matrix remodeling in vascular calcification associated with chronic kidney disease

Abstract

Vascular calcification is a major contributor to cardiovascular disease, a leading cause of death in patients with chronic kidney disease. Mechanistic studies high-light the importance of dysregulated mineral metabolism, vascular osteochondrogenic processes, apoptosis, and deficiencies in calcification inhibitors as potential mediators of calcification in renal disease. However, the contribution of the extracellular matrix in vascular calcification associated with chronic kidney disease is less understood. Here we examine evidence that suggests important roles for elastin and elastin-degrading enzymes as potential key regulators of calcification. Additional studies aimed at further understanding their role are critical for the design of therapeutic interventions. Copyright © 2010 by the American Society of Nephrology.
