Exposure to 2.4 GHz RF-EMF increased cry1 mRNA expression, weakened miR-34a's inhibition of per2 and abolished its inhibition of survivin, and eliminated miR-34a's effects on proliferation and migration in DLD1 cells.

Plain English Summary

Summary written for general audiences

Researchers exposed miR-34a-transfected DLD1 colorectal cancer cells to 2.4 GHz RF-EMF for 24 hours and evaluated effects using real-time PCR, scratch assay, and MTS test. Administration of miR-34a decreased expression of per2, bmal1, sirtuin1, and survivin and inhibited proliferation and migration of DLD1 cells. RF-EMF exposure increased cry1 mRNA expression, weakened miR-34a's inhibition of per2, abolished its inhibition of survivin, and eliminated miR-34a's effects on proliferation and migration. The authors concluded that RF-EMF strongly influenced miR-34a-mediated regulation of the peripheral circadian oscillator in DLD1 cells.

Why This Matters

Radiofrequency electromagnetic fields exert pleiotropic effects on biological processes including circadian rhythms. miR-34a is a small non-coding RNA whose expression is modulated by RF-EMF and can regulate clock gene expression. The interference between RF-EMF and miR-34a-mediated regulation of the circadian oscillator had not been elucidated before this study.

Quick Questions About This Study

Researchers exposed miR-34a-transfected DLD1 colorectal cancer cells to 2.4 GHz RF-EMF for 24 hours and evaluated effects using real-time PCR, scratch assay, and MTS test.
Administration of miR-34a decreased expression of per2, bmal1, sirtuin1, and survivin and inhibited proliferation and migration of DLD1 cells.
RF-EMF exposure increased cry1 mRNA expression, weakened miR-34a's inhibition of per2 and abolished its inhibition of survivin. It also eliminated miR-34a's effects on proliferation and migration.
The authors concluded that RF-EMF strongly influenced regulation mediated by the tumour suppressor miR-34a on the peripheral circadian oscillator in DLD1 cells.
