Hyperoxia-induced IL-1β elevation in the lung airspace is suppressed in ASK1 KO mice.

<p>WT and ASK1 KO mice were exposed to 100% O₂ for 48 or 72 h. The concentrations of IL-1β (pg/mL) in supernatants of BAL fluid were determined using ELISA. Results (means ± SEM; n = 4 in each group) are shown. The noted experiments are representative of a minimum of two similar evaluations. * p < 0.05.
