Figure 2

Effects of RF-EMF exposure on the protein expression levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG) as determined by histological analysis. Representative images of DNA damage in the sham-exposed (RF (−), n = 6) and 8-month RF-exposed (RF (+), n = 6) mouse brain. The expression of 8-OHdG was examined by immunohistochemical staining (upper panel) and subsequent quantification (lower panel). Both sham-exposed and RF-exposed groups showed increased 8-OHdG expression compared with that in young-aged controls (3M C, n = 3). Scale bar: 50 μm. The values are presented as means ± SEM. * p < 0.05 versus young-aged (3M C) group. n.s.: no significance.
