Plain English Summary
Researchers tested whether cell phone radiation triggers the cellular stress response in mammalian cells by measuring heat-shock factor activation, a key protein that responds to cellular stress. They exposed hamster, mouse, and human cells to both low (0.6 W/kg) and high (5 W/kg) levels of cell phone frequency radiation but found no activation of this stress response pathway. This suggests that cell phone radiation at these levels does not trigger the specific cellular stress mechanism that some scientists theorized could contribute to cancer development.
Study Details
The determination of whether nonthermal effects of radiofrequency electromagnetic radiation contribute to the process leading to malignancy is an important task. One proposed pathway to malignancy involves the induction of the stress response by exposures to cell phone frequency microwaves.
The first step in the induction of the stress response is the activation of the DNA-binding activity...
The DNA-binding activity of HSF was monitored using a gel shift assay; the calibration of this assay...
Our results do not support the notion that the stress response is activated as a consequence of exposure to microwaves of frequencies associated with mobile communication devices.
