Abstract

LOX-1 ligands containing apolipoprotein B (LAB) reflect ligand activity of LOX-1, which is a key molecule for initiation of atherosclerosis. The Zucker rat is a well-known model used for research on obesity and diabetes. Blood levels of LAB were compared among Zucker fatty (ZF), Zucker diabetic fatty (ZDF) and Zucker lean (ZL) rats. Log-transformed LAB was significantly higher in ZF and ZDF rats than in control ZL rats, while no significant difference was found in log-transformed LAB of ZF and ZDF rats. This study for the first time demonstrated that circulating LOX-1 ligands were elevated in obesity and diabetes model rats.

Keywords: Diabetes mellitus; LOX-1; Obesity; Oxidative stress; Zucker rats.
