Research Abstract

Oxidized LDL receptor (LOX-1) further increased oxidative stress that was induced by dietary manipulations. Under this condition, liver developed fatty liver with fibrosis which resembles NASH in human and atherosclerosis developed in the kidney and aorta. Renin inhibitor or antioxidants reversed changes in the liver. It was suggested that local renin-angiotensin system in the liver may be an intermediate in the vicious cycle of oxidative stress and LOX-1. And targeting renin-angiotensin system may be a possible therapeutic target in metabolic syndrome.
