Nur77 expression is increased in the lung after LPS-induced injury. A: Western blot analysis showing expression of Nur77, Nor1, and Nurr1 in whole lung tissues at various time points after LPS (100 µg). B: densitometry analysis of Nur77, Nor1, and Nurr1 expression. BSL, baseline. *P < 0.05 vs. baseline group, n = 5.
