(1) MR overactivation increases NADPH oxidase activity to induce a series of oxidative stress responses in adult rat models, leading to the inflammatory and fibrotic process, finally results in the cardiac lesions such as myocardial hypertrophy, ventricular remodeling, myocardial ischemia/infarction, and ultimately to the development and progression of cardiovascular disease and renal disease (13, 14). This evidence concerns the gene NR3C2 and cardiac hypertrophy.
