Western blot analysis of eNOS protein in the lung of eNOS+/+ mice (lane 1) and eNOS−/− mice 1 day after intratracheal administration of vehicle (lane 2), transfection with AdCMVβgal (lane 3), or transfection with AdCMVeNOS (lane 4). eNOS protein levels are expressed as gel unit per mg protein. n = 6. *, P < 0.05 when compared with eNOS+/+; **, P < 0.05 when compared with the eNOS−/− + AdCMVβgal group.
