Effects of α1AT and RS113456 on nuclear translocation of NF-κB in whole lung. Silica produces a marked increase in NF-κB levels and this is about 50% suppressed by both antiproteases at 2 hours. At 24 hours, some protection is still present with α1AT treatment. Lane 1, control; Lane 2, silica alone; Lane 3, silica + α1AT; Lane 4, silica + RS113456.
