Hypercholesterolemia Induces Side-Specific Phenotypic Changes and Peroxisome Proliferator–Activated Receptor-γ Pathway Activation in Swine Aortic Valve Endothelium

Abstract

In a large animal model at high spatial resolution, endothelium on the pathosusceptible side of the aortic valve leaflet is responsive to hypercholesterolemia. Transcript profiles indicative of a protective phenotype were induced and persisted on the side prone to aortic valve sclerosis.
