Continuous Wave and Simulated GSM Exposure at 1.8 W/kg and 1.8 GHz do not Induce hsp16-1 Heat-shock Gene Expression in Caenorhabditis elegans

Adam S. Dawe, Reetta Nylund, Dariusz Leszczynski, Niels Kuster, Tom Reader, and David I. De Pomerai, in Bioelectromagnetics, Volume 29, Issue 2, pp. 92–99. February 2008. Published online September 20, 2007

In this study the same transgenic hsp16-1::lacZ strain of C. elegans (PC72) as in the previous studies (De Pomerai et al (2000) and Dawe et al (2006)) was exposed to higher intensity RF fields (1.8 GHz; SAR 1.8 W kg-1). For both continuous wave (CW) and Talk-pulsed RF exposures (2.5 h at 25 °C), there was no indication that RF exposure could induce reporter expression above sham control levels. However, some evidence that reporter expression may be reduced by 15% following exposure to either Talk-pulsed or CW RF fields were reported under conditions where background reporter expression was moderately elevated in the sham control.
