The role of NADPH oxidases in diabetic cardiomyopathy
Systemic changes during diabetes such as high glucose, dyslipidemia, hormonal changes and low grade inflammation, are believed to induce structural and functional changes in the cardiomyocyte associated with the development of diabetic cardiomyopathy. One of the hallmarks of the diabetic heart is increased oxidative stress. NADPH-oxidases (NOXs) are important ROS-producing enzymes in the cardiomyocyte mediating both adaptive and maladaptive changes in the heart. NOXs have been suggested as a therapeutic target for several diabetic complications, but their role in diabetic cardiomyopathy is far from elucidated. In this review we aim to provide an overview of the current knowledge regarding the understanding of how NOXs influences cardiac adaptive and maladaptive processes in a “diabetic milieu”. This article is part of a Special issue entitled Cardiac adaptations to obesity, diabetes and insulin resistance, edited by Professors Jan F.C. Glatz, Jason R.B. Dyck and Christine Des Rosiers.
