NF-κB has no effect on inhibition of TRAIL-induced cell death by dexamethasone in A549 cells. A549 cells were infected with Ad-null or Ad-IκBα-SR at 20 m.o.i for 20 hr and then incubated with TRAIL or 12 hr pretreatment with dexamethasone. Cell viability was assessed by crystal violet assay 24 hr later.
