Sirt6 Suppresses High Glucose-Induced Mitochondrial Dysfunction and Apoptosis in Podocytes through AMPK Activation.

ABSTRACT: Previous studies have shown that mitochondrial dysfunction plays an important role in high- glucose(HG)-induced podocyte injury and thus contributes to the progression of diabetic nephropathy(DN). The histone deacetylase Sirtuin6 (Sirt6) has been revealed to have an essential role in the regulation of mitochondrial function in skeletal muscle and cardiomyocytes. However, its specific role in mitochondrial homeostasis in podocytes is undetermined. Here, we aimeds to explore the physiological function of Sirt6 in podocyte mitochondria and apoptosis under HG conditions and explore the possible mechanism. Herein, we observed that Sirt6-WT-1 colocalization was suppressed in the glomeruli of patients with DN. In addition, diabetic mice exhibited reduced Sirt6 expression and AMP kinase (AMPK) dep
