[Noise magnetic fields block co-suppression effect induced by power frequency magnetic field and phorbol ester].

Objectives: To explore intervention with electromagnetic noise for co-suppression effect on gap-junctional intercellular communication (GJIC) induced or strengthened by low intensity magnetic field with carcinogen 12-O-tetradecanoylphorbol-13-acetate (TPA).

Methods: Fibroblast cells from NIH 3T3 mice were exposed to extremely low intensity magnetic field (MF) 0.2 mT, 0.
