Effects of mobile phone radiation on reproduction and development in Drosophila melanogaster

In this report we examined the effects of a discontinuous radio frequency (RF) signal produced by a GSM multiband mobile phone (900/1,900 MHz; SAR ∼ 1.4 W/kg) on Drosophila melanogaster, during the 10‐day developmental period from egg laying through pupation. As found earlier with low frequency exposures, the non‐thermal radiation from the GSM mobile phone increased numbers of offspring, elevated hsp70 levels, increased serum response element (SRE) DNA‐binding and induced the phosphorylation of the nuclear transcription factor, ELK‐1. The rapid induction of hsp70 within minutes, by a non‐thermal stress, together with identified components of signal transduction pathways, provide sensitive and reliable biomarkers that could serve as the basis for realistic mobile phone safety guidelines.
