Hydrogen treatment protects against cell death and senescence induced by oxidative damage

In In vitro studies by CHESS

Hydrogen has potential for preventive and therapeutic applications as an antioxidant. However, micro- and macroparticles of hydrogen in water disappear easily over time. In order to eliminate reactive oxygen species (ROS) related with the aging process, the authors used functional water containing nanoparticle hydrogen. Nanoparticle hydrogen does not disappear easily and collapse under water after long periods of time. They …

Oral rinse with hydrogen-rich is helpful in treating dental diseases

In In vitro studies by CHESS

The accumulation of oral bacterial biofilm is the main etiological factor of oral diseases. Recently, electrolyzed hydrogen-rich water (H-water) has been shown to act as an effective antioxidant by reducing oxidative stress. In addition to this general health benefit, H-water has antibacterial activity for disease-associated oral bacteria. However, little is known about the effect of H-water on oral bacterial biofilm. …

Hydrogen-rich water achieves cytoprotection from oxidative stress injury in human gingival fibroblasts

In In vitro studies by CHESS

The aim of the present study is to investigate protective effects of hydrogen-rich water (HW) against reactive oxygen species (ROS)-induced cellular harmful events and cell death in human gingival fibroblasts (HGF) and three-dimensional (3D-) gingival tissue equivalents. HW was prepared with a magnesium stick in 600-mL double distilled water (DDW) overnight. Dissolved hydrogen was about 1460 ± 50 μg/L versus approximately 1600 μg/L for …

Molecular hydrogen inhibits lipopolysaccharide-triggered NLRP3 inflammasome activation

In In vitro studies by CHESS

The NLRP3 inflammasome, an intracellular multi-protein complex controlling the maturation of cytokine interleukin-1β, plays an important role in lipopolysaccharide (LPS)-induced inflammatory cascades. Recently, the production of mitochondrial reactive oxygen species (mtROS) in macrophages stimulated with LPS has been suggested to act as a trigger during the process of NLRP3 inflammasome activation that can be blocked by some mitochondria-targeted antioxidants. Known …

Hydrogen-rich medium ameliorates lipopolysaccharide-induced barrier dysfunction

In In vitro studies by CHESS

Gastrointestinal barrier dysfunction is associated with the severity and prognosis of sepsis. Hydrogen gas (H2) can ameliorate multiple organ damage in septic animals. Ras homolog gene family member A (RhoA) and mammalian diaphanous-related formin 1 (mDia1) are important to regulate tight junction (TJ) and adherens junction (AJ), both of which determine the integrity of the intestinal barrier. This study was …

Molecular hydrogen modifies free radical-dependent generation of oxidized phospholipid mediators

In In vitro studies by CHESS

The authors previously showed that H2 acts as a novel antioxidant to protect cells against oxidative stress. Subsequently, numerous studies have indicated the potential applications of H2 in therapeutic and preventive medicine. Moreover, H2 regulates various signal transduction pathways and the expression of many genes. However, the primary targets of H2 in the signal transduction pathways are unknown. Here, the …

Mitogen-activated protein kinase and heat shock protein are critical to the protective effect of hydrogen

In In vitro studies by CHESS

Molecular hydrogen (H2 ) has been proven to be an effective agent that can cure multiple organ diseases by reducing oxidative stress. Although the protective effect of hydrogen on acute pancreatitis (AP) has been confirmed, its molecular mechanism is still unclear. In this article, the authors aimed to investigate the changes in pancreatic cell protein expression associated with the protective …

Molecular hydrogen suppresses activated Wnt/β-catenin signaling

In In vitro studies by CHESS

Molecular hydrogen (H2) is effective for many diseases. However, molecular bases of H2 have not been fully elucidated. Cumulative evidence indicates that H2 acts as a gaseous signal modulator. The authors found that H2 suppresses activated Wnt/β-catenin signaling by promoting phosphorylation and degradation οf β-catenin. Either complete inhibition of GSK3 or mutations at CK1- and GSK3-phosphorylation sites of β-catenin abolished …

Molecular hydrogen alleviates cellular senescence in human endothelial cells

In In vitro studies by CHESS

Substantial evidence indicates that molecular hydrogen (H2) has beneficial vascular effects because of its antioxidant and/or anti-inflammatory effects. Thus, hydrogen-rich water may prove to be an effective anti-aging drink. This study examined the effects of H2 on endothelial senescence and clarified the mechanisms involved. Hydrogen-rich medium was produced by a high-purity hydrogen gas generator. Human umbilical vein endothelial cells (HUVECs) …
