STIM1 Restores Coronary Endothelial Function in Type 1 Diabetic Mice

Abstract

Impaired ER Ca(2+) refilling in diabetic MCECs, due to the decrease in STIM1 protein expression, attenuates endothelium-dependent relaxation in diabetic coronary arteries, while STIM1 overexpression has a beneficial and therapeutic effect on coronary endothelial dysfunction in diabetes.
