Mitigation of 3.5 GHz Electromagnetic Field-Induced BV2 Microglial Cytotoxicity by Polydeoxyribonucleotide
This in vitro study exposed BV2 mouse microglial cells to 3.5 GHz EMF for 2 hours and reports reduced cell growth and increased apoptosis alongside oxidative stress and signaling changes. The authors report that ROS generation and activation of JNK-1/2 and p38 MAPK were key events in the observed cytotoxicity. Polydeoxyribonucleotide (PDRN) reportedly reduced several EMF-associated cytotoxicity markers, suggesting a potential mitigating effect under the tested conditions.
Key points
- The study evaluates 3.5 GHz EMF exposure effects in BV2 mouse microglial cells.
- A 2-hour exposure is reported to inhibit cell growth and increase apoptosis-related outcomes.
- Reported cytotoxicity markers include increased ROS and genomic DNA fragmentation.
- Signaling changes reported include involvement of JNK-1/2, p38 MAPK, ERK-1/2, eIF-2α, and caspase-9-related proteins.
- Pharmacological experiments reportedly implicate ROS and JNK/p38 MAPK activation as key steps in the cytotoxic response.
- PDRN is reported to mitigate multiple EMF-associated changes, including ROS and JNK/p38 MAPK and caspase-9 activation.
- PDRN reportedly does not alter EMF-associated eIF-2α phosphorylation.
