H2HUBB TAKEAWAY
In a laboratory model, all of the results indicated that hydrogen decreased the levels of reactive oxygen species, 8‑iso‑prostaglandin F2α and malondialdehyde, and promoted the UVB exposure‑induced expression of PI3K, Akt, Nrf2 and heme oxygenase‑1 in HaCaT cells. 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 inhaled hydrogen gas was evaluated in this publication and summarizes the source-grounded findings below. All of the results indicated that hydrogen decreased the levels of reactive oxygen species, 8‑iso‑prostaglandin F2α and malondialdehyde, and promoted the UVB exposure‑induced expression of PI3K, Akt, Nrf2 and heme oxygenase‑1 in HaCaT cells.
What the Researchers Studied
The study used a in vitro cell-culture laboratory experiment.
What Effects Did Molecular Hydrogen Have?
For instance, in 2007, Ohsawa et al (44) indicated that hydrogen reduced the oxidative stress damage induced by focal ischemia and reperfusion of the brain by selectively reducing hydroxyl radicals and peroxynitrite (another cytotoxic ROS) in vitro. Also, hydrogen attenuated acute kidney injury induced by pacreatitis through inhibition of ROS in patients (45). All of the results indicated that hydrogen decreased the levels of reactive oxygen species, 8‑iso‑prostaglandin F2α and malondialdehyde, and promoted the UVB exposure‑induced expression of PI3K, Akt, Nrf2 and heme oxygenase‑1 in HaCaT cells. Molecular hydrogen exerts protective effects on UV‑induced injury, but the underlying mechanisms have remained elusive. The present study assessed the protective effects of hydrogen against oxidative stress‑induced injury caused by UVB irradiation and investigated the molecular mechanisms.
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.
