View Original AbstractGSM cell phone radiation up to 5 W/kg didn't trigger heat shock proteins in rat skin, but this measures only one type of cellular stress response.
Plain English Summary
Researchers exposed hairless rats to cell phone radiation (GSM-900 and GSM-1800 signals) for up to 12 weeks to see if it would trigger heat shock proteins, which are cellular stress markers that indicate when cells are under strain. The study found no changes in these stress proteins at any exposure level tested, including levels up to 5 watts per kilogram. This suggests that under these experimental conditions, the cell phone radiation did not cause detectable cellular stress in rat skin.
Study Details
We previously reported the inability of Global System for Mobile communication (GSM) signals at 900 (GSM-900) and 1800 (GSM-1800) MegaHertz (MHz) to induce morphological and physiological changes in epidermis of Hairless rats. The present work aimed at investigating heat shock proteins (HSP) expression – as a cellular stress marker – in the skin of Hairless rats exposed to GSM-900 and -1800 signals.
We studied the expression of the Heat-shock cognate (Hsc) 70, and the inducible forms of the Heat-sh...
Our data indicated that neither single nor repeated exposures altered HSP expression in rat skin, ir...
Under our experimental conditions (local SAR <5 W/kg), there was no evidence that GSM signals alter HSP expression in rat skin.
