[Apoptosis-related gene expression of human villous trophoblasts exposed to 50 Hz magnetic field].

ABSTRACT

OBJECTIVE: To study apoptosis-related gene expression of human villous trophoblasts exposed to 50 Hz magnetic field and to investigate the possible mechanism of human reproductive health effects caused by 50 Hz magnetic field. METHODS: Cultured human villous trophoblasts were exposed to 50 Hz magnetic field at 0.4 mT for 6, 48, 72 hours. Gene expressions of Bcl-2, Bax, Caspase-3, p53 and Fas were analyzed using real-time reverse transcription polymerase chain reaction (RT-PCR) assay. RESULTS: Within 72 hours, the average fold change for each gene was near 1.00, and there was no significant difference on expression pattern in each gene between exposure and control groups (P > 0.05). CONCLUSION: 0.4 mT 50 Hz magnetic field does not affect the apoptosis-related gene expression of human villous trophoblasts in vitro.
