TL;DR
Drinking hydrogen-rich water may help reduce lung damage and promote healing in cells exposed to a harmful chemical.
Key Finding
In laboratory-grown lung cells exposed to paraquat toxin, hydrogen water reduced markers of lung scarring and boosted the cells' natural antioxidant defenses by activating a protective pathway called Nrf2.
Summary
Researchers exposed human lung cells in a lab dish to paraquat (a toxic chemical) and then treated them with hydrogen water. Cells treated with hydrogen water showed reduced production of scar-forming proteins and increased production of natural antioxidants (molecules that protect cells from damage). The protective effect appeared to work through a cellular pathway called Nrf2.
Practical Takeaway
This is an early-stage laboratory study in cells only, not humans or animals. While the results suggest hydrogen water may protect lung cells from a specific type of chemical damage, much more research would be needed to determine if this translates to real-world benefits for people exposed to paraquat or other lung stressors.
Abstract
Objective: To investigate the effects of hydrogen water on proliferation, differentiation, collagen secretion and Nrf2 expression in paraquat-induced human lung fibroblasts. Methods: In vitro cultured human lung fibroblasts (HFL1) exposed to 600 μmol/L paraquat (PQ) for 24 h were treated with hydrogen water with or without RNA interference of Nrf2 expression. The changes in the cell proliferation were examined using MTT assay, and the expressions of Col-I, Col-III, α-SMA and Nrf2 in the cells were detected using Western blotting, real-time quantitative PCR and immunofluorescence assay. The contents of SOD, CAT and GSH in the cells were determined with ELISA. Results: Compared with the PQ-exposed cells, the cells with hydrogen water treatment showed significantly lowered expressions of Col-I, Col-III, and α-SMA. Interference of Nrf2 expression obviously attenuated the effect of hydrogen water on PQ-exposed cells. Hydrogen water treatment significantly increased the expression of Nrf2 and promoted the production of the antioxidants in PQ-exposed lung fibroblasts. Conclusions: Hydrogen water enhances Nrf2 expression to promote the proliferation and production of antioxidants and inhibit the differentiation and collagen secretion in PQ-exposed human lung fibroblasts in vitro.
