DMBT1 concentration in the supernatant of DMBT1− and DMBT1+ A549 cells is reduced by acetylcysteine. ELISA analysis of DMBT1 production in A549 cells stably transfected with a plasmid encoding the largest DMBT1 isoform or an empty control plasmid. Cells were either treated with 15 mM acetylcysteine (ACC) or sodium chloride as control for 2 h and DMBT1 concentration was measured 0 and 24 h after incubation. Values are expressed as box plots of 3 replicates. ACC: acetylcysteine
