Impact of Long-Term RF-EMF on Oxidative Stress and Neuroinflammation in Aging Brains of C57BL/6 Mice.
This animal study exposed 14-month-old C57BL/6 mice to 1950 MHz RF-EMF (SAR 5 W/kg) for 8 months. The authors report that aging was associated with increased oxidative damage, DNA damage, apoptosis, and glial activation markers in brain tissue. Long-term RF-EMF exposure did not change these markers in aged mice and did not alter locomotor activity.
Key points
- Middle-aged mice were exposed to 1950 MHz RF-EMF for 8 months at SAR 5 W/kg (2 h/day, 5 days/week).
- Aged mice showed higher oxidative damage markers (3-nitro-tyrosine, 4-hydroxy-2-nonenal) than young mice.
- Aged mice also showed increased DNA damage and apoptosis-related markers (e.g., 8-OHdG, γH2AX, cleaved caspase-3).
- Markers of astrocytes (GFAP) and microglia (Iba-1) were elevated with aging.
- RF-EMF exposure did not change oxidative stress, DNA damage, apoptosis, astrocyte, or microglia markers in aged brains.
- RF-EMF exposure did not alter locomotor activity in aged mice.
