Western Blot Analysis for cJun and PCNA. Protein expressions of cJun and PCNA in lungs exposed to different doses of cigarette smoke for 6 weeks. Representative Western Blot analyses are shown that used anti-cJun, and anti-PCNA antibodies. The size of the detected cJun and PCNA were 39 kDa and 36 kDa, respectively. The intensity of the protein signal was determined by densitometry analysis (three samples in each group). The relative protein values in the three treatment groups were calculated as a mean value ± standard deviation (SD) of the data relative (ratio) to control with the control set at 1.0. Different letters represent significant difference among groups (P < 0.05)
