Disruption of ATP Synthase Spatiotemporal Organization, Ca2+ Dynamics, and Contractile Function in Senescent Cardiomyocytes

Aging Cell, Volume 25, Issue 2, February 2026.
Enhanced ATP hydrolysis, ΔΨm flickering, and destabilized ATP synthase dimers collectively reduce ATP availability in senescent cardiomyocytes. This energy deficit is associated with disrupted Ca2⁺ dynamics and contractility. ABSTRACT Heart disease is the leading cause of death in the elderly population.
