Effect of power-frequency magnetic fields on genome-scale gene expression in Saccharomyces cerevisiae med./bio.

Published in: Radiat Res 2003; 160 (1): 25-37

Aim of study (acc. to author)

To clarify the existence of an effect of high-intensity 50 Hz magnetic fields on genome-wide gene expression in yeast.

Main outcome of study (acc. to author)

The magnetic field exposure did not cause significant changes in expression for proteins or genes that were related to heat-shock response, DNA repair, respiration, protein synthesis and the cell cycle.
The data provide no evidence that the magnetic field exposure alters the fundamental mechanism of translation and transcription in eukaryotic cells.
