Abstract
In mammals, the physiological activation of the glucocorticoid receptor (GR) by glucocorticoids (GCs) promotes the maturation of cardiomyocytes during late gestation, but the effect on postnatal cardiac growth and regenerative plasticity is unclear. Here we demonstrate that the GC–GR axis restrains cardiomyocyte proliferation during postnatal development. Cardiomyocyte-specific GR ablation in conditional knockout (cKO) mice delayed the postnatal cardiomyocyte cell cycle exit, hypertrophic growth and cytoarchitectural maturation. GR-cKO hearts showed increased expression of genes involved in glucose catabolism and reduced expression of genes promoting fatty acid oxidation and mitochondrial respiration. Accordingly, oxygen consumption in GR-cKO cardiomyocytes was less dependent on fatty acid oxidation, and glycolysis inhibition reverted GR-cKO effects on cardiomyocyte proliferation. GR ablation or transient pharmacological inhibition after myocardial infarction in juvenile and/or adult mice facilitated cardiomyocyte survival, cell cycle re-entry and division, leading to cardiac muscle regeneration along with reduced scar formation. Thus, GR restrains heart regeneration and may represent a therapeutic target.

Heatmap of GR target genes significantly upregulated during early postnatal development. The list of genes whose expression is induced upon administration of dexamethasone, a synthetic GR agonist, by direct binding of GR to their promoter, was obtained from previous works (Severinova et al., 2019). The expression of these genes was evaluated in the cardiac tissue during early postnatal development, by employing publicly available data on postnatal day 1 (P1) to postnatal day 9 (P9) heart lysates (Talman et al., 2018). 15 out 51 genes were significantly upregulated from P1 to P9 (pvalue < 0.05).

Extended Data Fig. 9 GR transient inhibition facilitates cardiomyocyte proliferation and heart repair in the mouse model.
Schematic diagram showing the role of GR in controlling postnatal cardiomyocyte proliferation and heart regenerative ability. Cardiac GR abundance physiologically increases in cardiomyocytes during the first week of postnatal life (red line) and endogenous glucocorticoids/GR axis in cardiomyocytes contributes to the maturation of myofibrils-mitochondria organization coupled with a metabolic rewiring from glucose catabolism to fatty acid oxidation, in turn resulting in cardiomyocyte cell cycle exit and loss of cardiac regenerative ability. Transient inhibition of GR in adulthood facilitates cardiomyocyte proliferation and heart repair after damage.
