Radiofrequency radiation-induced gene expression

Abstract

These gene expression shifts are generally adaptive, helping restore cellular homeostasis. Numerous studies have documented alterations in gene expression following exposure to radiofrequency radiation (RFR), the type of energy emitted by wireless communication devices. Findings - Key genes affected by RFR are involved in protein repair, cellular stress response, oxidative processes, apoptosis, DNA damage detection and repair, and neural function regulation. - Gene expression data supports the classification of RFR as a stressor that induces oxidative changes, DNA damage, and protein damage across various biological systems and exposure conditions. - These significant gene expression changes are corroborated by findings from other biological studies on RFR exposure. - Major guidelines (e.g., ICNIRP, IEEE) set 0.4 W/kg SAR as safe, but 40 gene expression effects were observed at or below this threshold, raising questions about international safety standards. - Over 200 studies have reported biological effects at SAR levels below 0.4 W/kg, further challenging current regulatory models. Discussion Gene expressions are tightly regulated and can demonstrate complex, sometimes non-linear responses to RFR depending on various parameters. While not all studies observe significant effects, substantial evidence indicates that RFR can influence gene expression related to cell stress, DNA processes, and brain function even at low exposure levels. Some studies provide direct evidence of increased translation of genes into functional proteins following RFR exposure, highlighting the importance of considering proteomic changes for a comprehensive understanding of health impacts. Two key areas for future research are emphasized: - Detailed mechanisms of cellular stress from RFR exposure, including involvement of the hypothalamic-pituitary-adrenal axis and limbic system. - Systematic study of cellular oxidative processes, particularly the induction of free radicals by RFR and the potential role of low-frequency modulations. Conclusion Alterations in gene expression, especially at environmental levels of RFR exposure, are clearly documented. Current evidence underscores the need for further research and consideration in the development of RFR exposure guidelines, as changes in genes and subsequent protein translation may sustain both health and illness. Importantly, similar gene expression effects have been reported with exposure to extremely low-frequency electromagnetic fields, reinforcing concerns over EMF-related health risks.

Main findings

The review states that numerous studies report altered gene expression after radiofrequency radiation exposure, with affected genes involved in cellular stress responses, oxidative processes, apoptosis, DNA damage detection/repair, protein repair, and neural function regulation. It notes that while not all studies find significant effects, gene expression effects have been reported at or below 0.4 W/kg SAR (a level referenced in major guidelines), and it cites over 200 studies reporting biological effects below 0.4 W/kg SAR.

Outcomes measured

• gene expression changes
