Plain English Summary
Turkish researchers exposed rats to cell phone radiation (900 MHz) for 3 hours daily over an entire year and found it altered microRNA in brain tissue. MicroRNAs are tiny molecules that control gene activity and play crucial roles in brain function, cell growth, and death. This study demonstrates that chronic radiofrequency exposure can disrupt these fundamental cellular control mechanisms in the brain.
Why This Matters
This research breaks important new ground by examining how long-term RF exposure affects microRNAs, the molecular switches that regulate gene expression throughout the body. The fact that researchers found measurable changes in brain microRNA after one year of exposure at relatively low SAR levels (0.037 W/kg) is significant because it suggests cumulative biological effects from chronic use. What makes this particularly relevant is that the exposure duration and daily use pattern closely mirrors real-world cell phone usage patterns. The science demonstrates that radiofrequency radiation isn't just passing through our tissues harmlessly. Instead, it's creating measurable molecular changes in the brain's regulatory systems. While this study examined only a few specific microRNAs out of hundreds that exist, the fact that any were altered suggests broader impacts on cellular function that warrant serious investigation.

Where This Falls on the Concern Scale
Study Details
The purpose of this study was to bridge this gap by investigating effects of long-term 900 MHz mobile phone exposure on some of the miRNA in brain tissue.
The study was carried out on 14 Wistar Albino adult male rats by dividing them into two groups: Sham...
Results revealed that long-term exposure of 900 MHz RF radiation only decreased rno-miR107 (adjP* = ...
900 MHz RF radiation can alter some of the miRNA, which, in turn, may lead to adverse effects. Therefore, further studies should be performed.
