Aim of study (acc. to author)

To assess the reproducibility of the 60 Hz magnetic field-induced transcription changes of c-fos, c-jun and c-myc oncogenes in human lymphoblastoid cells reported by Phillips et al. (publication 913).

Chamber magnetic field or sham exposure was made in matching Forma 3158 incubators placed 3 m apart
Setup a pair of square Helmholtz coils (37 x 37 cm²) placed 19 cm apart; four flasks containing cells were placed within the central zone (17 x 17 x 5 cm) of the coil, where the magnetic field was uniform within 1%. The coils were energized in a buck mode for sham exposure.
