This in vitro study exposed HaCaT human keratinocytes to 1760 MHz RF-EMF (SAR 4.0 W/kg; 2 h/day for 4 days). The authors report increased intracellular ROS and increased expression/activity of several matrix metalloproteinases, along with increased phosphorylation of FoxO3a and ERK1/2. Cell growth/viability and…
Human keratinocytes in culture exhibit no response when exposed to short duration, low amplitude, high frequency (900 MHz) electromagnetic fields in a reverberation chamber.

This in vitro study exposed normal human epidermal keratinocytes to non-thermal 900 MHz electromagnetic fields in a mode-stirred reverberation chamber under two short-duration conditions. Microarray analysis found only limited gene modulation (20 genes) with small expression ratios and no shared genes across…
