Disruption of the calcineurin/NFAT4 pathway attenuates MV-induced pathological changes, edema and MPO activity in the lungs of rats. (A and B) Pretreatment with CsA inhibited MV-induced pathological changes. Pretreatment with CsA decreased (C) the wet/dry weight ratios and (D) the protein levels of BALF. (E) Pretreatment with CsA inhibited the MV-induced MPO activity. The data are presented as the means ± SD (n=8). *P<0.05 compared with the Control group; #P<0.05 compared with the HV group. MV, mechanical ventilation; CsA, calcineurin inhibitor; LV, ventilated with a low tidal volume; HV, ventilated with a high tidal volume.
