SFTPC and acute respiratory distress syndrome: The RT-qPCR results show that the levels of spc, aqp5, claudin4 and keratin8 mRNA are markedly higher in the TAG + ARDS group compared with the ARDS group (ARDS vs. TAG + ARDS, 0.26 ± 0.09 vs. 0.76 ± 0.12, 0.44 ± 0.06 vs. 0.71 ± 0.05, 0.32 ± 0.06 vs. 0.59 ± 0.05, and 0.48 ± 0.11 vs. 0.72 ± 0.09, respectively, p < 0.01; Figures 5G, 6G).
