Electrochemically reduced water protects neural cells from oxidative damage

Area of Science:

• Neuroscience
• Biochemistry
• Cell Biology

Background:

• Aging-related neurodegenerative disorders are linked to mitochondrial dysfunction and oxidative stress.
• The brain is particularly vulnerable to reactive oxygen species (ROS) due to high metabolic activity.
• Electrolytically reduced water (ERW) has shown potential in scavenging ROS in various cell types.

Purpose of the Study:

• To investigate the protective effects of ERW against hydrogen peroxide (H2O2) and nitric oxide (NO) in neuronal cells.
• To elucidate the mechanisms underlying ERW's neuroprotective properties.

Main Methods:

• Utilized rodent neuronal cell lines (PC12, SFME, N1E-115) and primary cells.
• Exposed cells to H2O2 and NO to induce oxidative stress and cytotoxicity.
• Assessed cell viability, intracellular ROS levels, and calcium (Ca2+) influx.
• Investigated ERW's capacity to scavenge ROS and NO.

Main Results:

• ERW significantly reduced H2O2-induced cell death in PC12 and SFME cells.
• ERW scavenged intracellular ROS and protected N1E-115 neuronal networks from H2O2 damage.
• ERW suppressed NO-induced cytotoxicity in PC12 cells, although it did not scavenge NO directly.
• ERW inhibited glutamate-induced Ca2+ influx and subsequent cytotoxicity in primary cells.

Conclusions:

• ERW demonstrates significant neuroprotective effects against oxidative stress induced by H2O2 and NO.
• ERW functions primarily by scavenging ROS, attributed to dissolved hydrogen and platinum nanoparticles.
• These findings suggest ERW's potential therapeutic value for neurodegenerative conditions.
