Medical/biological Study (experimental study)
Magnetic field exposure enhances mRNA expression of sigma 32 in E. coli. med./biol. By: Cairo P, Greenebaum B, Goodman E
Published in: J Cell Biochem 1998; 68 (1): 1 - 7 ( PubMed Entry , Journal web site )
Aim of study (according to author)
To examine the stress response in Escherichia coli exposed to a magnetic field.
The examined parameter was the transcription of Sigma 32 (σ32), a protein that is essential for the transcription initiation of heat shock protein genes. It enhances the RNA polymerase binding probability to promoter sides on DNA. Therefore sigma 32 represents a good marker of stress response in Escherichia coli.
- stress response (mRNA level of protein sigma 32)
General category: magnetic field, 50/60 Hz (AC)

bacterium (in vitro)
Methodsinvestigated material: DNA/RNA (in vitro)
time of investigation: after exposure
Main outcome of study (according to author)
The intracellular level of sigma 32 mRNA was significantly enhanced following the exposure to magnetic field.
