Abstract

Effect of extremely low frequency magnetic field (ELFMF) at 50 mT and 60 Hz on heat-induced expression of heat shock protein 70 (hsp-70) was examined in HL60RG cells. No increase in hsp-70 production was observed in the cells after exposure to 50 mT ELFMF alone. Simultaneous exposure to 50 mT ELFMF in combination with mild heat at 42 and 40 degrees C suppressed heat-induced hsp-70 expression. The suppression of hsp-70 occurred when cells were simultaneously exposed to both for longer periods of more than 5 h. However, the suppression of hsp-70 was not observed at a magnetic density of 5 and 0.5 mT. This result suggests that exposure to 50 mT ELFMF may act on a protection against the concomitant mild heat stress in HL60RG cells.
