Hyperoxia does not inhibit the ER stress response. A549 cells were exposed to room air (RA) or hyperoxia for 48 hours followed by 0.5ug/ml tunicamycin for 8 hours. (A) RNA was collected and RT-PCR for XBP1 was performed (u= unspliced XBP1, s=spliced XBP1). (B) Whole cell lysates were immunoblotted for phospho-PERK and BiP. Data represent similar results from three independent experiments.
