The endoplasmic reticulum is an organelle sensitive to a wide variety of environmental insults and involved in a number of pathologies. The frequency range of 60 GHz was considered in the context of the near-future applications in wireless communication systems.
As a positive control for stress induction, cells were treated for 16 h with thapsigargin or proteasome inhibitor MG132 or subjected to heat shock (3 h at 42°C; expression of HSP70 was monitored as control).
|Distance between exposed object and exposure source||21 cm|
|Setup||exposure chamber placed inside an incubator; walls of chamber lined with absorbing material; culture plates placed in the far field opposite the pyramidal horn antenna|
|Sham exposure||A sham exposure was conducted.|
Exposure to low-power millimeter waves did not significantly modify the gene expression of these stress-sensitive genes suggesting that endoplasmic reticulum homeostasis was not altered by low-power millimeter waves at the considered frequencies.
