Plain English Summary
Canadian researchers exposed mice to 1.9 GHz radiofrequency radiation (similar to cell phone signals) for 4 hours daily over 5 days and examined gene activity in seven different brain regions. They found no consistent changes in gene expression at exposure levels of 0.2 or 1.4 W/kg, though they acknowledge their study may have missed very small changes below 1.5-fold. This suggests that short-term RF exposure at these levels doesn't significantly alter how genes function in the brain.
Study Details
To assess 1.9 GHz radiofrequency (RF) field exposure on gene expression within a variety of discrete mouse brain regions using whole genome microarray analysis.
Adult male C57BL/6 mice were exposed to 1.9 GHz pulse-modulated or continuous-wave RF fields for 4 h...
When analysis of gene expression was conducted within individual brain regions when controlling the...
The current study provides the most comprehensive analysis of potential gene expression changes in the rodent brain in response to RF field exposure conducted to date. Within the exposure conditions and limitations of this study, no convincing evidence of consistent changes in gene expression was found in response to 1.9 GHz RF field exposure.
