Electromagnetic fields regulate iron metabolism: From mechanisms to applications

Abstract

Category: Biomedical Science Tags: electromagnetic fields, iron metabolism, disease progression, ROS, translational medicine, cellular regulation, EMF safety DOI: 10.1016/j.jare.2025.04.044 URL: sciencedirect.com Overview Electromagnetic fields (EMFs), utilized as a form of physical therapy, have seen widespread application in biomedicine. Iron, as the most prevalent trace metal in living systems, is essential for various physiological processes. Disrupted iron metabolism is tightly linked to numerous disease developments. Substantial research shows that exposure to EMFs produces marked changes in both systemic and cellular iron metabolism. Key Scientific Concepts - EMFs influence disease progression by regulating iron metabolism. - This regulation by EMFs is highly specific to parameters and varies across tissues and cell types. - Iron-containing molecules/proteins and iron-rich tissues’ electromagnetic properties play a critical role in this modulation. - EMFs act through changes to membrane structure, ion channels, and by influencing Reactive Oxygen Species (ROS). Findings This review synthesizes current evidence and proposes mechanisms by which EMFs affect iron metabolism, focusing on the roles of special electromagnetic properties of iron-containing proteins/tissues, and on how EMFs influence membrane and ion channel function, as well as ROS activity. Current advances are summarized regarding the effects and safety of EMFs on iron metabolism and their impact on conditions such as: - Immunoregulation - Cardiovascular diseases - Neurological diseases - Orthopedic diseases - Diabetes - Liver injury - Cancer Conclusion and Perspective EMFs serve as a non-invasive alternative or adjunct in translational medicine. Their regulation of iron metabolism is a pivotal aspect of their biological impact, with significant roles in therapy and safety evaluation. Importantly, iron metabolism indicators can be used to assess EMF biological safety, and the modulation of iron metabolism by EMFs offers promising therapeutic applications across various diseases. Synergistic effects with drugs, especially iron-based nanoparticles, may further enhance the biomedical potential of EMFs. Despite inconsistencies and variable results in the literature, general patterns can be discerned—such as dependency on EMF properties (intensity, frequency, etc.), exposure time, and biological “windows” where specific EMF parameters yield pronounced effects. The review highlights the need for more standardized exposure protocols and reporting, as well as further research to establish clearer regulatory patterns. Overall, the connection between EMFs and iron metabolism underscores potential health risks and therapeutic opportunities, warranting careful evaluation of EMF exposure and further study for disease prevention and treatment.

Main findings

This review summarizes evidence that EMF exposure can produce marked changes in systemic and cellular iron metabolism, with effects described as parameter-dependent and varying across tissues and cell types. Proposed mechanisms include roles for electromagnetic properties of iron-containing proteins/tissues and EMF-related changes in membrane structure, ion channels, and ROS. The authors note inconsistencies and variable results across the literature and call for more standardized exposure protocols and reporting.

Outcomes measured

• Systemic iron metabolism
