In gene transfection assays, the effect of TNFalpha requires the presence of an inducible nuclear factor-kappaB ( NF-kappaB ) ( Rel A ) binding site in the IL-8 promoter .
 ( protein: TNFalpha, None) , ( DNA: IL-8 promoter, None) , ( protein: Rel A, None) , ( protein: NF-kappaB, None) , ( DNA: inducible nuclear factor-kappaB ( NF-kappaB ) ( Rel A ) binding site, None) , ( protein: IL-8, None)
