We have previously reported that Tead1, the transcriptional effector of Hippo pathway, is critical for maintaining adult cardiomyocyte function, and its deletion in adult heart results in lethal acute dilated cardiomyopathy. Growing lines of evidence indicate that Hippo pathway plays a role in regulating mitochondrial function, although its role in cardiomyocytes is unknown. Here, we show that Tead1 plays a critical role in regulating mitochondrial OXPHOS in cardiomyocytes. Assessment of mitochondrial bioenergetics in isolated mitochondria from adult hearts showed that loss of Tead1 led to a significant decrease in respiratory rates, with both palmitoylcarnitine and pyruvate/malate substrates, and was associated with reduced electron transport chain complex I activity and expression. Transcriptomic analysis from Tead1-knockout myocardium revealed genes encoding oxidative phosphorylation, TCA cycle, and fatty acid oxidation proteins as the top differentially enriched gene sets. Ex vivo loss of function of Tead1 in primary cardiomyocytes also showed diminished aerobic respiration and maximal mitochondrial oxygen consumption capacity, demonstrating that Tead1 regulation of OXPHOS in cardiomyocytes is cell autonomous. Taken together, our data demonstrate that Tead1 is a crucial transcriptional node that is a cell-autonomous regulator, a large network of mitochondrial function and biogenesis related genes essential for maintaining mitochondrial function and adult cardiomyocyte homeostasis.NEW & NOTEWORTHY Mitochondrial dysfunction constitutes an important aspect of heart failure etiopathogenesis and progression. However, the molecular mechanisms are still largely unknown. Growing lines of evidence indicate that Hippo-Tead pathway plays a role in cellular bioenergetics. This study reveals the novel role of Tead1, the downstream transcriptional effector of Hippo pathway, as a novel regulator of mitochondrial oxidative phosphorylation and in vivo cardiomyocyte energy metabolism, thus providing a potential therapeutic target for modulating mitochondrial function and enhancing cytoprotection of cardiomyocytes."xsd:string |
