The p65 subunit of NF-κB binds to PGC-1α, linking inflammation and metabolic disturbances in cardiac cells

Abstract

On the basis of these data, we propose that p65 directly represses PGC-1alpha activity in cardiac cells, thereby leading to a reduction in pyruvate dehydrogenase kinase 4 (PDK4) expression and the subsequent increase in glucose oxidation observed during the proinflammatory state.
