Effects of lipopolysaccharide (LPS) exposure on Krüppel-like factor 5 (KLF5) and nuclear factor-kappaB subunit protein expression in human bronchial epithelial cells. Cells from the (a) HBEC and (b) BEAS-2B lines were incubated with LPS (5 μg/mL) for various durations, and KLF5, p65, phospho-p65 (Ser276), and phospho-p65 (Ser536) protein expression were evaluated using western blotting. The time to peak intensities of KLF5, p65, Ser276, and Ser536 phosphorylation differed slightly. Data were obtained from 3 independent experiments.
