[The role of transcription factors in the response of mouse lymphocytes to low-level electromagnetic and laser radiations].
The effects of low-intensity laser radiation (LILR, 632.8 nm, 0.2 mW/cm2) and low-intensity electromagnetic waves (LIEW, 8.15 - 18 GHz, 1 MW/cm2) on the production of transcription factors in lymphocytes from NMRI male mice were examined. The total level of NF-KB and its phosphorylated metabolite Phospho-NF-kappaB, as well as the regulatory protein IkappaB-alpha were determined in spleen lymphocytes subjected to laser or microwave radiations. The proteins were determined by immunoblotting. Laser light induced a lowering in the level of NF-kappaB and IkappaB-alpha. By contrast, irradiation with electromagnetic waves resulted in a significant increase in the amount of NF-kappaB and IkappaB-alpha. The phosphorylated form of NF-kappaB did not noticeably change under either of the two kinds of radiation. The results showed that electromagnetic waves activate the production of both NF-kappaB and the regulatory protein IkappaB-alpha and these data confirm the stress character of the response of spleen lymphocytes to low-level microwaves of the centimeter range.
