H2HUBB TAKEAWAY
In mice, when H₂ -water was given for 14 days, no significant phenotype was observed as judged by body weight and the plasma levels of glucose and triglyceride ( Supplementary Figure S1 ). These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
What the Findings Mean
H2HUBB reviewed how molecular hydrogen affected the outcomes measured in mice. When H₂ -water was given for 14 days, no significant phenotype was observed as judged by body weight and the plasma levels of glucose and triglyceride ( Supplementary Figure S1 ).
What the Researchers Studied
The researchers studied mice. The study used a preclinical animal experiment. The comparison condition was control condition or baseline measurements.
What Effects Did Molecular Hydrogen Have?
HepG2 human hepatoma cells were treated with 2,2′-azobis(2-amidinopropane) dihydrochloride for 6 h in the presence or absence of 10% H₂. For 4-HNE treatment, cells were treated with 4-HNE for 1 h for analysis of phosphorylation or 6 h for analysis of gene expression in the presence or absence of 50% H₂. When H₂ -water was given for 14 days, no significant phenotype was observed as judged by body weight and the plasma levels of glucose and triglyceride ( Supplementary Figure S1 ). The authors concluded that the expression of PGC-1α might be regulated indirectly through sequential regulation by H₂, 4-hydroxy-2-nonenal, and Akt/FoxO1 signaling, as suggested in cultured cell experiments. Although the genes sodecenoyl-coenzyme A delta isomerase ( Dci ) and aldehyde dehydrogenase ( Aldh3aa2 ) associated with fatty acid metabolism are not currently classified as members of the PPARα pathway in the KEGG DataBase, they are target genes of PPARα, as described in a previous report.
Why These Findings Matter
These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
How Strong Is This Evidence?
This is preclinical animal evidence from a preclinical animal experiment. It is most informative for the disease model, mechanisms, biomarkers, and outcomes directly measured in the study.
