"Histopathological and immunohistochemical analyses revealed no significant difference between the sham-exposed and the RF-exposed groups (Figure 3). Dorsal skin treated with DMBA and then exposed to RF did not show any change in the epidermal thickness or in the number of nuclei stained by anti-proliferating cell nuclear antigen (PCNA) antibody. The tumorous skin of TPA-treated mice showed many anti-PCNA antibody stained nuclei (Figure 3). Although no detectable alterations were observed by histopathological and immunohistochemical analyses, we could not exclude the possibility that RF exposure might trigger the modulation of molecules involving cell proliferation. Figure 4 shows that the expression of c-fos and cyclin D1 were elevated in tumorous skin in the TPA-treated mice. In contrast, no expression elevation was detected in sham-, 849 MHz-, 1,763 MHz-exposed, or non-tumorous TPA-treated mouse skin (Figure 4)."
