研究目的(著者による)

To study whether whole of gestation exposure of fetal mouse brain to mobile phone radiofrequency fields produces a stress response detectable by induction of heat shock proteins.

詳細情報

Pregnant mice (n=10) were exposed and prior to parturition on day 19, fetal brains (n=10, one fetal brain of each litter) were collected.
Positive controls were performed (thermal stress).

研究の主なアウトカム(著者による)

There was no induction of HSP32 or HSP70 in any brains, while HSP25 expression was limited to two brainstem nuclei and occured consistenly in exposed and non-exposed brains.
In conclusion, using HSP as oxidative stress marker, the data showed that whole gestation exposure of fetal mouse brains to mobile phone radiofrequency fields did not produce any stress response.
