Mitochondria are the major source of cellular energy metabolism. In the cardiac cells, mitochondria produce by way of the oxidative phosphorylation more than 90% of the energy supply in the form of ATP, which is utilized in many ATP-dependent processes,…

Molecular hydrogen (H2) has an anti‐oxidant effect on hundreds of animal models. However, the exact molecular mechanisms of molecular hydrogen still remains elusive. Mitochondrial unfolded protein response (mtUPR) is a known stress response to perturbed mitochondrial proteostasis caused by oxidative…

Molecular hydrogen (H2) is recognized as a medical gas applicable to numerous diseases including neurodegenerative diseases, metabolic disorders, and rheumatoid arthritis. Although the efficacy of H2 is reportedly attributed to its scavenging capability against the hydroxyl radical, the mechanisms underlying…

Molecular hydrogen (H2) was believed to be an inert and nonfunctional molecule in mammalian cells; however, we overturned the concept by reporting the therapeutic effects of H2 against oxidative stress. Subsequently, extensive studies revealed multiple functions of H2 by exhibiting…
