2.45 GHz Microwave Radiation Impairs Learning and Spatial Memory via Oxidative/Nitrosative Stress Induced p53-Dependent/Independent Hippocampal Apoptosis: Molecular Basis and Underlying Mechanism
This animal study exposed male Swiss mice to 2.45 GHz continuous-wave microwave radiation for 2 hours/day over 15, 30, or 60 days. The authors report increased hippocampal oxidative/nitrosative stress and increased apoptosis in neuronal and nonneuronal hippocampal subfields. They also report duration-dependent impairments in spatial learning and memory, correlated with reduced dendritic spines and neuronal arborization, and conclude involvement of p53-dependent/independent pathways.
Key points
- Animal experiment in 12-week-old male Swiss mice exposed to 2.45 GHz continuous-wave microwaves.
- Exposure conditions included 0.0248 mW/cm^2 power density and whole-body SAR 0.0146 W/kg for 2 h/day.
- Spatial learning and memory were assessed using the Morris Water Maze.
- The study reports increased oxidative/nitrosative stress in the hippocampus after both short- and long-term exposure.
- The study reports enhanced apoptosis in hippocampal neuronal and nonneuronal cells across DG, CA1, CA2, and CA3 regions.
- Reported behavioral deficits increased with exposure duration (15 < 30 < 60 days).
- Reported memory deficits were correlated with decreased neuronal arborization and dendritic spine density.
- Authors attribute findings to oxidative/nitrosative stress with p53-dependent and p53-independent apoptotic signaling.
