Fig. 2: Inhibition of IKKβ decreased ETS-1 expression.

Cal27CP (a), SCC25C (b), and FaDu-CP (c) cells were treated with increasing concentrations of IKKβ inhibitor, CmpdA, for 24 h and phosphorylation and total levels of SRC, p65, and expression of ETS-1 and β-actin were detected by Western blot analysis.
