Metabolic homeostasis is maintained in myocardial hibernation by adaptive changes in the transcriptome and proteome

► The hibernation process was dissected into an initiation and a maintenance phase. ► Glibenclamide, an inhibitor of K(ATP) channels, blocked GLUT1 induction. ► The maintenance phase was characterized by attenuated tissue hypoxia. ► Phosphorylation of myosin light chain 2 and cardiac troponin I was reduced. ► Combining of proteomics and transcriptomics improved the bioinformatic pathway analysis.
