Stress is increasingly associated with cardiac disease. Glucocorticoids are primary stress hormones that regulate homeostasis through two nuclear receptors, the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Cardiomyocytes express both receptors but little is known concerning their specific and coordinated actions in heart physiology and pathology. To examine the in vivo function of glucocorticoid signaling in the heart, we generated mice with cardi...
