Integrin β1 (A, B) and vimentin (C, D) protein expression assessed with Western Blot in Mel270 (A, C) and BLM (B, D) cells treated with different doses (1, 3, 5 Gy) of proton beam or X rays. Cells were lysed 20 and 40 days after irradiation. (E) 20 μg of protein was applied per well. Control of untreated cells was set to a 100%. Chemiluminescent evaluation of 3 independent Western blots of cell lysates was shown as a mean of the percentage of the control and SEM. *p<0.05; **p<0.01; ***p<0.001.
