| Outline of Final Research Achievements |
The therapeutic potential of molecular hydrogen is emerging in a number of human diseases and in their animal models. However, the molecular mechanism in these hydrogen effects has not been elucidated enough. We showed that H2 supplementation increases gastric expression of mRNA encoding ghrelin and ghrelin secretion, which are antagonized by the β1-adrenoceptor blocker. Thus, we focused on β-adrenoceptor signaling to investigate the molecular mechanism of action induced by hydrogen. Ghrelin gene promotor activity assay, real-time analysis of intracellular cAMP measurements, and in vivo analysis with mouse provided evidence that molecular hydrogen enhances β-adrenoceptor signal.
