Cardiovascular disease is the leading cause of death in chronic kidney disease. Extracellular matrix remodeling is implicated in atherosclerosis development. This study investigated the effects and possible mechanism of type I collagen expression on radial artery elasticity in patients with end-stage renal disease (ESRD). ⋯ Type I collagen expression is an essential factor for radial artery elasticity dysfunction in patients with ESRD. Uremic toxins apparently induced a phenotypic transition of the rat aortic VSMCs, leading to increased type I collagen secretion and subsequent extracellular matrix remodeling.
