Role for Matrix Metalloproteinase-2 in Oxidized Low-Density Lipoprotein–Induced Activation of the Sphingomyelin/Ceramide Pathway and Smooth Muscle Cell Proliferation

Abstract
Background— Oxidized LDLs (oxLDLs) and matrix metalloproteinases (MMPs) are present in atherosclerotic lesions. OxLDLs activate various signaling pathways potentially involved in atherogenesis. OxL...
