Detection of TNF-α and RANTES expression in Cal27 cells. (A) 14-3-3ζ and Stat3 protein expression in Cal27 cells after 14-3-3ζ vector or/and Stat3 siRNA transfection; (B) Western blot analysis of TNF-α and RANTES expression in Cal27 cells transfected with 14-3-3ζ vector or/and Stat3 siRNA. Gene expression was normalized to β-actin. At least three independent experiments were performed. *p < 0.05 vs. Control, #p < 0.05 vs. 14-3-3ζ vector.
