Plain English Summary
Researchers exposed human brain tumor cells to 1950 MHz radiofrequency radiation (similar to 3G cell phone frequencies) at various intensities for up to 2 hours. While the radiation didn't affect cell growth or activate major stress response proteins, it did reduce a specific cellular protection mechanism at the highest exposure level (10 W/kg). This suggests that even when cells appear unaffected, subtle molecular changes may still be occurring.
Study Details
To study the effects of exposure to a 1950 MHz radio frequency field on expression of Hsp70 and Hsp27 in human glioma cells.
Human glioma MO54 cells were used to investigate whether radio frequency (RF) field exposure could a...
It was found that sham exposed and RF exposed cells demonstrated a similar growth pattern up to 4 d...
Our results suggest that although exposure to a 1950 MHz RF field has no effect on cell proliferation and expression of Hsp 27 and Hsp70, it may inhibit the phosphorylation of Hsp27 at Serine 78 in MO54 cells.
