The expression levels of SPC and AQP5 proteins in the ARDS group were lower than in the Sham but increased under the TAG pretreatment (ARDS vs. TAG + ARDS, 0.28 ± 0.08 vs. 0.71 ± 0.04 and 0.49 ± 0.08 vs. 0.79 ± 0.08, respectively, p < 0.01; Figures 5E, F). Here, AQP5 is linked to acute respiratory distress syndrome.
