Genotoxic Effects in Human Fibroblasts Exposed to Microwave Radiation.
This in vitro study exposed human fetal and adult fibroblasts to 25 GHz microwave radiation and assessed multiple genotoxic and cellular endpoints. The authors report no evidence of direct DNA damage and no apoptosis or changes in prosurvival signalling proteins. However, they report increased total and centromere-positive micronuclei, which they interpret as aneuploidy induction via chromosome loss.
Key points
- The study evaluates genotoxic and cellular effects of 25 GHz microwave exposure in human fetal and adult fibroblasts in vitro.
- Comet assay and H2AX phosphorylation results are reported as excluding direct DNA damage under the tested conditions.
- CREST-negative micronuclei frequency is reported as not indicating direct DNA damage.
- No apoptosis induction or changes in prosurvival signalling proteins were detected.
- CREST analysis showed increased total micronuclei and centromere-positive micronuclei in exposed samples.
- The authors interpret the centromere-positive micronuclei increase as evidence of aneuploidy due to chromosome loss.
