This study indicate that smooth muscle cells differentiation to osteoblast-like cells and the associated media remodeling, which includes disruption of elastic lamellas and deposition of collagen are, at least in part, associated with the increased arterial stiffness observed in CKD rats with vascular calcification.
This study shows that ETA receptor blockade reduced vascular inflammation, smooth muscle cells differentiation, calcification and stiffness indicating a pivotal role for ET-1 in medial vascular calcification in this rat remnant kidney model of CKD with mineral imbalance. Therefore, the endothelin system may be a potential therapeutic target for improving cardiovascular morbidity in patients with CKD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
