5G Radiofrequency Exposure Reduces PRDM16 and C/EBP � mRNA Expression, Two Key Biomarkers for Brown Adipogenesis
This animal study exposed juvenile and young adult Wistar rats to 5G (3.5 GHz) or 2G (900 MHz) radiofrequency fields (1.5 V/m) for 1–2 weeks and measured brown adipose tissue-related gene expression by RT-qPCR. The abstract reports significant downregulation of PRDM16 and C/EBP mRNA after 5G exposure, while UCP1-dependent thermogenesis markers were not significantly changed at the transcriptional level. The authors interpret these findings as a potential partial disruption of brown adipocyte differentiation and raise EMF safety concerns, while calling for further confirmatory research.
Key points
- Rats were assigned to 5G (3.5 GHz), 2G (900 MHz), or sham exposure groups.
- Exposure was described as low-intensity (1.5 V/m), delivered in two 1-hour sessions daily for 1 or 2 weeks.
- After 5G exposure, PRDM16 mRNA and C/EBP mRNA were reported to be significantly reduced versus sham.
- The abstract reports no significant transcriptional effect on UCP1-dependent thermogenesis.
- Most thermogenic markers were reported as unrelated to age or exposure duration, with exceptions noted for PPARα and ADRβ3.
- The conclusions emphasize possible impacts on brown adipocyte differentiation and thermoregulation and recommend additional physiological measurements in future work.
