Hematoxylin and eosin (H&E) staining was used to assess the effect of GPT on skeletal and cardiac muscle in aged mice. Protection against age-induced cellular damage by GPT was assessed in C2C12 and H9c2 cells using β-galactosidase staining. Mitochondrial morphology, structure, and function were analyzed using transmission electron microscopy, Seahorse assays, and ATP content measurements. Potential mechanisms by which GPT regulates mitochondrial homeostasis were examined using Western blot analysis.Results: GPT treatment significantly improved the alignment of skeletal muscle fibers, reduced gaps, and increased the cross-sectional area (CSA) of skeletal muscle in aged mice. It also reduced the CSA of cardiac muscle fibers, alleviating cardiomyocyte hypertrophy. Mitochondrial morphology was restored, and GPT reduced D-gal-induced β-galactosidase elevation. Furthermore, GPT protected mitochondrial morphological and structural integrity in the skeletal and cardiac muscles of aged mice and improved mitochondrial respiratory function and ATP levels in D-gal-injured C2C12 and H9c2 cells. GPT treatment increased the levels of mitochondrion-associated proteins PGC-1α, PPARγ, Nrf1, and OPA1 in the skeletal and cardiac muscle of aged mice. Moreover, GPT modulated Drp1 expression, with increases in aged skeletal muscle and decreases in aged cardiac muscle.Conclusion: These findings suggest that GPT helps maintain mitochondrial homeostasis by regulating mitochondrial remodeling, thereby alleviating skeletal and cardiac muscle damage in aged mice.
