| Research Abstract |
Mismatch between cardiomyocyte growth and reduced coronary angiogenesis promotes maladaptive cardiac remodeling including diabetic cardiomyopathy. Diabetes enhances cardiac aminopeptidase activity which promotes degradation in angiogenic chemokine SDF1-α, leading to reduced coronary angiogenesis and resultant cardiac remodeling. Our data suggest that regulation of cardiac aminopepetidase activity may be essential for therapeutic strategy of maladaptive cardiac remodeling in diabetes.
