a Representative images of DAPI (blue: nuclear) and NF-κB (red) stained PP-exposed A549 cells. b Representative western blotting analysis of p-NF-κB, NF-κB, Nuclear-NF-κB, and Lamin B in PP-exposed A549 cells. c The relative densities analysis of p-NF-κB levels. Data were normalized against NF-κB. d Relative density analysis of Nuclear-NF-κB. Data were normalized against Lamin B. Data are means ± SD (n = 3 per group). ^#P ≤ 0.05; ^##P ≤ 0.01; vs. VC
