Abstract

Pancreatic beta-cell dysfunction and Insulin resistance are observed in type 2 diabetes. Under diabetic conditions, oxidative stress and ER stress are induced in various tissues, leading to activation of the JNK pathway. This JNK activation suppresses Insulin biosynthesis and interferes with Insulin action. Indeed, suppression of the JNK pathway in diabetic mice improves Insulin resistance and ameliorates glucose tolerance. Thus, the JNK pathway plays a central role in pathogenesis of type 2 diabetes and may be a potential target for diabetes therapy.
