Effect of C. aronia L. on the Expression of PARP-1, Caspase-3, Bcl-2 and Bax Proteins in A549 Cells. (A) Representative western blot showing expression of target proteins in A549 cells exposed to C. aronia L. (150 and 300 µg/ml) extract. Levels of proteins were adjusted to the GAPDH protein (housekeeping gene). (B) The expression of proteins was normalized to the GAPDH, and the ratios were presented in arbitrary units (a.u.). Protein band intensity of target proteins was measured by ImageJ software. Data are presented as the mean ± SEM for 3 independent experiments
