de Pomerai DI, Smith B, Dawe A, North K, et al. (2003):

This group has previously shown that RF radiation can induce the formation of heat-shock proteins in the C. Elegans nematode. In a new study they demonstrate that exposure to RF radiation promotes the aggregation of bovine albumin. This change occurred in a time- and temperature-dependent fashion. In a separate experiment they showed that the radiation caused bovine insulin to undergo amyloid fibril changes. The RF radiation used was at 1.0GHz and 0.5 W, and the SAR averaged 0.015-0.02 W/kg, with a peak of 0.05.

The authors suggest that it is these changes in protein conformation that induce the heat-shock response that they showed earlier. In another experiment they show that in the C. Elegans, the heat-shock responses to microwaves are suppressed if the regulator Heat Shock Factor is first ablated.

The authors emphasize that that these studies do not prove that RF radiation produces harmful effects on humans. In fact, they say that it is conceivable that moderate microwave radiation might even prove beneficial. They feel, however, that their latest experiments provide further evidence that RF radiation can produce non-thermal biological effects.
