Study type: Medical/biological study (experimental study)

Radio frequency radiation effects on protein kinase C activity in rats' brain. med./bio.

Published in: Mutation Research - Fundamental and Molecular Mechanism of Mutagenesis 2004; 545 (1-2): 127-130

Aim of study (acc. to author)

To study the effect of amplitude modulated radiofrequency irradiation on calcium-dependent protein kinase C (PKC) activity on developing rat brain.

Background/further details

PKC was determined in whole brain, hippocampus and whole brain minus hippocampus separately.

Main outcome of study (acc. to author)

A significant decrease in the enzyme level was revealed in the exposed animals in comparison to the sham-exposed animals (whole brain and hippocampus). The phenomen is non-thermal in nature. These findings indicate that this type of irradiation could affect membrane bound enzymes associated with cell signaling, proliferation and differentiation. This may also suggest an effect on the behavior of chronically exposed rats.
