Involvement of the p38 MAPK signaling cascade in stress response of RAW 264.7 macrophages
Abstract
Overview
The pivotal role of the p38 MAPK signaling cascade in the RAW 264.7 macrophages' stress response to low-intensity centimeter microwaves was explored in this study.
Findings
- Enhanced Cytokine Production: Exposure resulted in elevated levels of various cytokines such as IL-1, IL-6, TNF-α, INF-γ, and IL-10.
- Activation of Signaling Cascades: Significant activation was observed in NF-κB and p38 MAPK signaling cascades along with increased expression of the Hsp72 heat shock protein.
- Impact of p38 MAP Kinase Inhibitor: When the p38 MAP kinase inhibitor XI was applied, it mitigated the stimulating effects of electromagnetic waves either completely (NF-κB and Hsp72) or partially (p38 MAPK and cytokines).
Conclusion
The findings underscore a significant sensitivity of the p38 MAPK signaling pathway to the impacts of low-intensity electromagnetic fields, highlighting potential health risks associated with electromagnetic exposure in biological systems.
