H2HUBB TAKEAWAY

In C57BL/6 mice, culturing in the hydrogen-rich medium selectively suppressed the generation of hydroxyl radicals in hepatocytes and significantly suppressed hepatocyte death induced by antimycin A; however, it did not suppress hepatic stellate cell activation. These results are preclinical and suggest that molecular hydrogen did not improve the measured outcome. Further human research is needed to determine its clinical relevance.

What the Researchers Studied

The study examined this study aimed to investigate the effects of hydrogen water on liver fibrogenesis and the mechanisms underlying these effects.

How Molecular Hydrogen Was Used

C57BL/6 mice were fed with hydrogen water or control water, and subjected to carbon tetrachloride, thioacetamide and bile duct ligation treatments to induce liver fibrosis. Hepatocytes and hepatic stellate cells were isolated from mice and cultured with or without hydrogen to test the effects of hydrogen on reactive oxygen species-induced hepatocyte injuries or hepatic stellate cell activation.

What the Researchers Found

Oral intake of hydrogen water significantly suppressed liver fibrogenesis in the carbon tetrachloride and thioacetamide models, but these effects were not seen in the bile duct ligation model. Culturing in the hydrogen-rich medium selectively suppressed the generation of hydroxyl radicals in hepatocytes and significantly suppressed hepatocyte death induced by antimycin A; however, it did not suppress hepatic stellate cell activation.

H₂ Mechanisms / Biological Findings

Reported molecular-hydrogen-related mechanisms included this study aimed to investigate the effects of hydrogen water on liver fibrogenesis and the mechanisms underlying these effects.

Authors’ Conclusion

The authors concluded that hydrogen water protects hepatocytes from injury by scavenging hydroxyl radicals and thereby suppresses liver fibrogenesis in mice.
