Syrian hamster dermal cell immortalization is not enhanced by power line frequency electromagnetic field exposure. med./biol. By: Gamble SC, Wolff H, Arrand JE
Published in: Br J Cancer 1999; 81 (3): 377 - 380 ( PubMed Entry , Journal web site )
Aim of study (according to author)
This in vitro study was performed to investigate the effects of electromagnetic fieds on the cell immortalization of hamster dermal cells in the presence or absence of a known carcinogen (gamma radiation, at 0.5 or 1.5 Gy)
Syrian hamster dermal cells were chosen as investigated cell line as they show very low frequency of spontaneous immortalization. Cell immortalization can be a sign of tumor initiation.
The cells were exposed to electromagnetic fields at the levels commonly encountered in the home.
General category: magnetic field, 50/60 Hz (AC), power transmission line
FIELD View further expo parameters
intact cell/cell culture (in vitro)
SHD (syrian hamster dermal) cells
Methodsinvestigated material: intact cell/cell culture (in vitro)
time of investigation: after exposure
Main outcome of study (according to author)
The electromagnetic field exposure alone did not cause cell immortalization in the investigated cell line. Furthermore the electromagnetic fields exposures did not enhance the frequency of ionizing radiation-induced immortalization.
