H2HUBB TAKEAWAY
In Human umbilical vein endothelial cells (HUVECs) were incubated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for various time periods in normal or hydrogen-rich medium, however, HUVECs incubated in hydrogen-rich medium did not exhibit these TCDD-induced changes accompanying Nrf2 activation, which was observed even after H2was undetectable in the medium. The authors concluded that hydrogen-rich water may thus be a functional drink that increases longevity. (Circ J 2016; 80: 2037-2046). These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
What the Findings Mean
H2HUBB reviewed how hydrogen-rich medium affected the outcomes measured in Human umbilical vein endothelial cells (HUVECs) were incubated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for various time periods in normal or hydrogen-rich medium. However, HUVECs incubated in hydrogen-rich medium did not exhibit these TCDD-induced changes accompanying Nrf2 activation, which was observed even after H2was undetectable in the medium.
What the Researchers Studied
The researchers studied Human umbilical vein endothelial cells (HUVECs) were incubated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for various time periods in normal or hydrogen-rich medium. The study used a in vitro cell-culture laboratory experiment.
What Effects Did Molecular Hydrogen Have?
Source-reported hydrogen concentration: 0.55 ± 0.07 mM H₂ (≈1.11 ± 0.141 mg/L). However, HUVECs incubated in hydrogen-rich medium did not exhibit these TCDD-induced changes accompanying Nrf2 activation, which was observed even after H2was undetectable in the medium. The authors concluded that hydrogen-rich water may thus be a functional drink that increases longevity. (Circ J 2016; 80: 2037-2046).
Why These Findings Matter
These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
How Strong Is This Evidence?
This is laboratory evidence from a in vitro cell-culture laboratory experiment. It is most informative for the biological mechanisms, cellular responses, or biochemical outcomes directly measured.
