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.

Liraglutide Ameliorates Injury‐Related Vascular Repair by Activating Autophagy Through Modulation of the PI3K–mTOR Signaling Pathway

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
Liraglutide inhibits chronic stress‐induced vascular injury in mice by inhibiting the activation of the PI3K‐mTOR signaling pathway and promoting autophagy of smooth muscle cells or macroautophagy. ABSTRACT Chronic stress is a significant risk factor for postoperative restenosis and other cardiovascular diseases, as it can promote the intimal ...
