Short exposures to 60 Hz magnetic fields do not alter MYC expression in HL60 or Daudi cells
No Effects Found
Authors not listed · 1995
Rigorous testing found no gene activation from 60 Hz magnetic fields, challenging claims linking power line EMF to cancer.
Plain English Summary
Summary written for general audiences
Researchers exposed human cancer cells (HL60 and Daudi) to 60 Hz magnetic fields at various intensities for 20-60 minutes, looking for changes in gene expression that might explain cancer risks. Despite testing a wide range of conditions and using rigorous controls, they found no changes in MYC gene activity or other genetic markers. This challenges earlier studies that claimed power line frequencies rapidly activate cancer-related genes.

}Quick Questions About This Study
No. Despite testing various intensities from 5.7 microT to 10 mT for 20-60 minutes, researchers found no changes in MYC gene expression or other genetic markers in human HL60 and Daudi cancer cells.
The researchers used blind exposures and internal standards that earlier studies lacked. When they replicated experiments in the original laboratory that reported effects, they still found no gene activation from magnetic fields.
The study tested a wide range from 5.7 microT (barely detectable) to 10 mT (extremely high), covering typical household exposures and far beyond what you'd encounter from power lines or appliances.
This study found no genetic mechanism at the cellular level that would support cancer risk from 60 Hz fields. However, it's one study among many, and cancer research requires multiple lines of evidence.
Exposure times ranged from 20 to 60 minutes. The researchers tested various durations to see if longer exposures might trigger genetic changes, but found no effects at any time point tested.
