In skeletal muscle, calcium is not only essential to stimulate and sustain their contractions but also for muscle embryogenesis, regeneration, energy production in mitochondria, fusion. Different ion channels contribute achieving the various functions of muscles. Muscle contraction initiated by releasing from sarcoplasmic reticulum through ryanodine receptor gated mechanically four dihydropyridine receptors T-tubules. The influx store-operated sustains stimulates regeneration. Mitochondrial uniporter allows entry into mitochondria oxidative phosphorylation. Aging alters expression activity these different channels, resulting a reduction force generation regeneration capacity.

Vascular aging contributes to adverse changes in organ function and is a significant indicator of major cardiac events. Endothelial cells (ECs) participate aging-provoked coronary vascular pathology. Regular exercise associated with preservation arterial humans. However, the molecular basis not well understood. The present study was aimed determine effects on endothelial senescence whether mitochondrial clearance regulator FUN14 domain containing 1 (FUNDC1)-related mitophagy homeostasis were involved. In mouse arteries, FUNDC1 levels showed gradually decrease age. Both microvascular (CMECs) significantly reduced aged mice rescued by training. Exercise also alleviated CMECs as evidenced β-galactosidase activity markers, prevented abnormal cell migration, proliferation, eNOS activation from mice, improved endothelium-dependent vasodilation artery, myocardial neutrophil infiltration inflammatory cytokines evoked MI/R, restored angiogenesis consequently MI/R injury aging. Importantly, deletion abolished protective roles overexpression ECs adeno-associated virus (AAV) reversed injury. Mechanistically, PPARγ played an important role regulating expressions endothelium under exercise-induced laminar shear stress. conclusion, prevents arteries via increasing PPARγ-dependent manner, subsequently protects against These findings highlight FUNDC1-mediated potential therapeutic target that vulnerability.
