Angiotensin II Promotes Glucose-Induced Activation of Cardiac Protein Kinase C Isozymes and Phosphorylation of Troponin I

Activation of the protein kinase C (PKC) family is a potential signaling mechanism by which high ambient glucose concentration modulates the phenotype and physiological function of cells. Recently, the cardiac renin angiotensin system (RAS) has been reported to promote PKC translocation in the diabetic heart via the angiotensin (ANG) II type 1 receptor (AT-1R). To evaluate the molecular events coupled with high glucose-induced PKC translocation...
