Nuclear translocation of c-Fos and c-Jun proteins in cervical cancer cells. SiHa, HeLa, C-33A and HaCaT cells were fixed with paraformaldehyde, permeabilized with saponin, stained with anti-c-Fos or anti-c-Jun antibodies FITC-conjugated, and were analyzed by immunofluorescence microscopy by FITC in a Nikon Elipse 400 epifluorescence microscope using the 40× Fluor objective. The arrows indicate the nuclear localization of c-Fos (A) and c-Jun protein (B) in SiHa (a–c), HeLa (d–f), C-33A (g–i) and HaCaT cells (j–l). Scale bar, 50 μm. The data are representative of three independent experiments
