EFFECTS OF EXTREMELY LOW FREQUENCY MAGNETIC FIELDS ON CYTOSOLIC FREE CALCIUM: EVALUATION OF CELL CYCLE DEPENDENCE

Previous results from our lab have suggested that calcium signalling in cells in G2-M phases of the cell cycle was increased with extremely low frequency magnetic field exposure. The objective of this study is to determine which magnetic field conditions elicit an effect on cytosolic free calcium concentration ([Ca2+]c). Synchronized Jurkat E6.1 cells were exposed to a null static magnetic field, a parallel combination of 60 Hz, 100 µTpeak sinusoidal (AC) and 78.1 µT static (DC) magnetic fields, the AC field alone or the DC field alone. Unlike the previous experiments, no significant differences in [Ca2+]c were detected between exposure conditions
