Diabetic cardiomyocyte dysfunction and myocyte insulin resistance: Role of glucose-induced PKC activity

Increased protein kinase C (PKC) activity has been implicated in the pathogenesis of a number of diabetic complications, and high concentrations of glucose have been shown to increase PKC activity. The present study was designed to examine the role of PKC in diabetes-induced (and glucose-induced) cardiomyocyte dysfunction and insulin resistance (measured by glucose uptake). Adult rat ventricular myocytes were isolated from nondiabetic and type 1...
