The PCR products were electrophoresed and photographed using AlphaEaseFC. After transfected with 25 nmol/L decoy ODN, the whole A549 were harvested and the whole-cell extracts were obtained. And western blotting for bcl-x1 and cyclin D1 were then examined as described in materials and methods. Histogram presented the relative expression level of each gene or protein after normalization to its corresponding internal control. Statistical significance was determined as *< 0.01 and < 0.05 compared to control
