> mechanism that induces the expression of stress response genes, e.g.,
> HSP70, and increased levels of stress proteins, e.g., hsp70. The 20
> different stress protein families are evolutionarily conserved and act
> as 'chaperones' in the cell when they 'help' repair and refold damaged
> proteins and transport them across cell membranes. Induction of the
> stress response involves activation of DNA, and despite the large
> difference in energy between ELF and RF, the same cellular pathways
> respond in both frequency ranges. Specific DNA sequences on the
> promoter of the HSP70 stress gene are responsive to EMF, and studies
> with model biochemical systems suggest that EMF could interact directly
> with electrons in DNA. While low energy EMF interacts with DNA to
> induce the stress response, increasing EMF energy in the RF range can
> lead to breaks in DNA strands. It is clear that in order to protect
> living cells, EMF safety limits must be changed from the current
> thermal standard, based on energy, to one based on biological responses
> that occur long before the threshold for thermal changes.
