Abstract (original English)
IntroductionAdipose-derived mesenchymal stem cells (ADSCs) are promising candidates for regenerative therapies, but their clinical application is limited by cellular aging. This study investigated the effects of hydrogen on ADSC senescence and myogenic differentiation, along with the underlying molecular mechanisms.MethodsADSCs were treated with hydrogen gas. Senescence was assessed using β-galactosidase staining, proliferation assays, measurements of mitochondrial oxidative stress, and protein expression analysis. Differentiation capacity was evaluated through MyHC immunofluorescence, MYOD expression profiling, and quantification of myogenic regulatory factors. Additionally, the key molecular pathway of hydrogen's action was investigated by pharmacologically inhibiting PRDX6.ResultsThe findings showed that hydrogen treatment reduced senescence and increased differentiation capacity, as evidenced by higher proportions of MyHC-positive cells, increased myogenin levels, and decreased Muscle RING finger protein1 (MuRF1) expression. Molecular investigations revealed activation of the PRDX6/SIRT1/PGC-1α axis, accompanied by elevated NQO-1 expression. Importantly, pharmacological inhibition of PRDX6 largely eliminated the protective effects of hydrogen on cellular aging, disrupted differentiation, and caused mitochondrial dysfunction.DiscussionThese results suggest that hydrogen can
