Abstract
Diabetic cardiomyopathy (DCM) describes the abnormality of myocardial structure and function caused by diabetes, and Yes-associated protein (Yap) is linked to various cardiovascular diseases, modulating remodeling and cardiac function in hearts, but its role in DCM is unclear. How Yap affects myocardial structure and function in mice with type 2 diabetes mellitus and the underlying pathways were investigated. High glucose or high glucose plus palmitic acid levels enhance Yap activity, thereby promoting miR-22-3p expression and inhibiting sirtuin 1 (Sirt1) expression. The Yap-miR-22-3p-Sirt1 axis plays critical roles in the cause of DCM. The molecular pathways investigated offer promising targets for therapeutic intervention against DCM and provide new insights into the development of innovative treatment strategies to combat cardiac dysfunction in patients with diabetes.
