Abstract

Weak Radiofrequency Field Effects on Chemical Parameters That Characterize Oxidative Stress in Human Fibrosarcoma and Fibroblast Cells Gurhan H, Bajtoš M, Barnes F. Weak Radiofrequency Field Effects on Chemical Parameters That Characterize Oxidative Stress in Human Fibrosarcoma and Fibroblast Cells. Biomolecules. 2023 Jul 13;13(7):1112. doi: 10.3390/biom13071112. Abstract In the last few decades, evidence has surfaced that weak radiofrequency (RF) fields can influence biological systems. This work aims to improve our understanding of how externally applied weak RF fields alter concentrations of chemical parameters that characterize oxidative stress. We conducted a series of experiments to investigate the effects of applying weak RF magnetic fields within the 3-5 MHz region on mitochondrial respiration in both human fibrosarcoma and fibroblast cells over a period of four days. Our experimental data show that RF fields between 3 and 5 MHz were able to change the modulation of mitochondrial signaling by changing the cell growth, mitochondrial mass, and oxidative stress. Exposure to RF fields at 4.2 MHz significantly increased the mitochondrial mass and oxidative stress in fibrosarcoma cells. There are substantial concerns that extended exposure to weak RF fields can lead to health effects. The ability to control these parameters by external magnetic fields may have important clinical implications. Open access paper: mdpi.com

Main findings

In experiments applying weak RF magnetic fields in the 3–5 MHz range to human fibrosarcoma and fibroblast cells for four days, the authors report changes in modulation of mitochondrial signaling associated with altered cell growth, mitochondrial mass, and oxidative stress. Exposure at 4.2 MHz is reported to significantly increase mitochondrial mass and oxidative stress in fibrosarcoma cells.

Outcomes measured

  • mitochondrial respiration
  • mitochondrial signaling modulation
  • cell growth
  • mitochondrial mass
  • oxidative stress (chemical parameters)

Limitations

  • No sample size reported in the abstract.
  • Exposure intensity/dose metrics (e.g., field strength, SAR) not reported in the abstract.
  • Statistical details beyond a statement of significance at 4.2 MHz are not provided in the abstract.
  • Findings are from in vitro cell models; generalizability to human health outcomes is not established in the abstract.
