In the present study we compared the proliferation behavior, the ultrastructural morphology and the glycolitic metabolism of K562 cells irradiated by low-power wide-band millimeter waves, with those of sham-exposed K562 cells (control), maintained in the same culture conditions. The gigaHertz radiation treatments, performed between 53–78 109 Hz, induced a noticeable inhibition of the cell proliferation that could be related to relevant ultrastructural changes. Such effects brought the irradiated cell system to lose the homeostasis and to trigger defense/reparatory mechanisms in order to reestablish a new steady state. 13C-Nuclear magnetic resonance data on the kinetic of glucose metabolism demonstrated that the irradiated cells enhanced the glycolitic aerobic pathway, indicating that such system need to produce an extra-bioenergy. Most of the ATP synthesized served probably to perform the above processes resulting in a significant decrease of the proliferation rate without significant cell death increment.
