Interestingly, we found the same cells reactive (e.g. fibroblasts, Table 2) or nonreactive (e.g. naïve lymphocytes, Table 3), when investigating protein synthesis. Resminostat This may
suggest a common underlying mechanism between DNA breaks and increased protein synthesis in reactive cells. With this exposure regime, the temperature difference between exposed cells and control cells was less than 0.15°C, we exclude a heat-related response. Heat-induced proteome alterations detectable with our proteome profiling methodology would require temperature differences greater than 1°C. Furthermore, a temperature increase of even 1°C does not affect e.g. TCP-1 family members (Gerner et al. 2002). We conclude that the warming of the cell cultures caused by RF exposure was too low to account for the present observations. Most of the proteins found to be induced by RF-EME are chaperones, which are mediators of protein folding. Since the applied electromagnetic fields were very weak, the direct and active denaturation of existing proteins by RF-EME exposure appears unlikely to underlie the observed increased level of protein synthesis. Resonance phenomena may concentrate radiation exposure-mediated physical check details energy on hot spots and have already been suggested to cause biological effects (Belyaev 2005). Indeed, exposure to low frequency electromagnetic fields caused effects, which were reduced by noise signals (Litovitz et al. 1997), providing further support for the concept of resonance as an underlying condition. Hydrogen bonds are known to resonate with microwaves.
