ANTXR1 pharmacological blockade also improved heart function in models of pressure overload and obesity-induced heart disease with preserved ejection fraction. Improved heart function was accompanied by enhanced exercise tolerance. Mechanistic studies revealed an ANTXR1-antibody-driven improvement in post-infarct scar formation followed by attenuation of late-stage, chronic TGFβ-mediated extracellular matrix remodeling.

Correlating these data with single-cell and bulk RNA sequencing data, we identify oxidative phosphorylation (OXPHOS) as a positive regulator of long-term regenerative outcome. OXPHOS levels, driven by glycolysis through the malate-aspartate shuttle, increase as soon as cardiomyocyte proliferation decreases, and this increase is required for cardiomyocyte re-differentiation and successful long-term regeneration. Reduced upregulation of OXPHOS in Astyanax mexicanus cavefish results in the absence of a dynamic temporal sarcomere gene expression program during cardiomyocyte re-differentiation.
