Effect of 900 MHz Electromagnetic Field Exposure During Different Trimesters of Pregnancy on TRPM2-Mediated Ferroptosis and Neurotoxicity in the Trigeminal Ganglion of Rats: Protective Role of Ferrostatin-1.
This animal study examined prenatal 900 MHz EMF exposure during different pregnancy trimesters and measured oxidative stress, inflammatory, apoptotic, and TRPM2-related markers in rat offspring trigeminal ganglia at postnatal day 28. The abstract reports increased oxidative stress/lipid peroxidation, inflammation, apoptosis, and TRPM2 activation after EMF exposure, most pronounced with mid-gestation exposure. Ferrostatin-1 given after each exposure session largely reversed these changes and reduced tissue damage, suggesting a ferroptosis-related mechanism in this model.
Key points
- Pregnant rats were exposed to 900 MHz EMF for 2 hours per day during early, mid, or late gestation.
- Offspring trigeminal ganglia were evaluated on postnatal day 28 using histopathological, immunohistochemical, and biochemical methods.
- The abstract reports reduced antioxidant capacity and increased lipid peroxidation and ROS in EMF-exposed groups.
- Pro-inflammatory cytokines and apoptotic markers were reported to be elevated after prenatal EMF exposure.
- TRPM2 activation was reported to increase, with the strongest alterations in the mid-gestation exposure group.
- Ferrostatin-1 administered after daily exposure largely normalized measured parameters and reduced structural damage.
