DETAILS * Non-thermal effects of terahertz radiation on gene expression in mouse stem cells. med./biol.
Alexandrov BS, Rasmussen KO, Bishop AR, Usheva A, Alexandrov LB, Chong S, Dagon Y, Booshehri LG, Mielke CH, Phipps ML, Martinez JS, Chen HT, Rodriguez G (2011), Biomed Opt Express 2 (9): 2679 - 2689
Aim: Mesenchymal mouse stem cells were exposed to Terahertz waves to study whether mammalian cells exhibit specific cellular and/or molecular effects, unrelated to the temperature changes. To examine the eventual thermal effect locally, i.e. in the cells, the Terahertz-induced transcriptional activation of hyperthermic genes was quantified, and their expression levels were compared with previously reported differentially expressed genes (Bock et al. 2010).
Endpoints: molecular biosynthesis (gene expression of selective hyperthermic genes )
System: intact cell/cell culture (in vitro): mouse mesenchymal stem cells
Exposure: 2.52 THz - 10 THz, radio frequency field, terahertz fields, CW (continuous wave), PW (pulsed wave)

* Effect of glutathione depletion, hyperthermia, and a 100-mT static magnetic field on an hsp70/luc reporter system. med./biol.
Belton M, Prato FS, Carson JJ (2011), Bioelectromagnetics 32 (6): 453 - 462
Exposure: static magnetic field, DC
