Little information is available about the effects of exposure to pulsed microwaves on neuronal Ca2+ signaling under non-thermal conditions. In this study, rat pheochromocytoma (PC12) cells were exposed to pulsed microwaves for 6 min at a specific absorption rate (SAR) of 4 W/kg to assess possible real-time effects. During microwave exposure, free calcium dynamics in the cytosol, mitochondria, and nucleus of cells were monitored by time-lapse microfluorimetry using a genetically encoded calcium indicator (ratiometric-pericam, ratiometric-pericam-mt, and ratiometric-pericam-nu). We established a waveguide-based real-time microwave exposure system under accurately controlled environmental and dosimetric conditions and found no significant changes in the cytosolic, mitochondrial, or nuclear calcium levels in PC12 cells. These findings suggest that no dynamic changes occurred in [Ca2+]c, [Ca2+]m, or [Ca2+]n of PC12 cells at the non-thermal level.
