Exposure to the extremely low-frequency electromagnetic field induces changes in the epigenetic regulation of gene expression in the endometrium.
This in vitro study exposed porcine endometrial slices from days 15–16 of pregnancy to a 50 Hz extremely low-frequency electromagnetic field for 2 hours. The authors report changes in several epigenetic-related markers, including DNA methylation machinery, histone-related measures (HDAC activity), global DNA methylation, and proteins involved in microRNA biogenesis. They conclude ELF-EMF may alter epigenetic regulation of gene expression in the endometrium and suggest this could disrupt peri-implantation uterine processes.
Key points
- Porcine endometrial slices (peri-implantation) were exposed in vitro to 50 Hz ELF-EMF for 2 hours.
- The study assessed epigenetic regulation components related to DNA methylation, histone regulation, and microRNA biogenesis.
- Changes were observed in DNMT1 and DNMT3a abundance and in EZH2 at mRNA and protein levels.
- EED and SUZ12 mRNA transcripts were also reported to change following exposure.
- Global DNA methylation level and HDAC activity were reported to change after ELF-EMF exposure.
- The authors interpret the findings as indicating potential disruption of uterine biological processes during peri-implantation.
