Popis: The role of canonical Wnt signaling in metabolic regulation and development of physiological cardiac hypertrophy remains largely unknown. To explore the function of &beta
catenin in the regulation of cardiac metabolism and physiological cardiac hypertrophy development, we used mice heterozygous for cardiac-specific &beta
catenin knockout that were subjected to a swimming training model. &beta
Catenin haploinsufficient mice subjected to endurance training displayed a decreased &beta
catenin transcriptional activity, attenuated cardiomyocytes hypertrophic growth, and enhanced activation of AMP-activated protein kinase (AMPK), phosphoinositide-3-kinase&ndash
Akt (Pi3K&ndash
Akt), and mitogen-activated protein kinase/extracellular signal-regulated kinases 1/2 (MAPK/Erk1/2) signaling pathways compared to trained wild type mice. We further observed an increased level of proteins involved in glucose aerobic metabolism and &beta
oxidation along with perturbed activity of mitochondrial oxidative phosphorylation complexes (OXPHOS) in trained &beta
catenin haploinsufficient mice. Taken together, Wnt/&beta
catenin signaling appears to govern metabolic regulatory programs, sustaining metabolic plasticity in adult hearts during the adaptation to endurance training.
