The expression of JAK/STAT and TGF-β/Smad signaling pathway-related proteins in the lung tissues of the different groups on days 7 and 28. A. Western blots of JAK/STAT signaling pathway-related proteins: JAK, STAT1, STAT3, STAT5, SOCS3, and phosphorylated STAT1, STAT3, and STAT5. B. A histogram of the relative gray values shown in A. C. Western blots for the TGF-β/Smad signaling pathway-related proteins: Smad1, Smad3, TGF-βR1 and phosphorylated Smad1 and Smad3. D. A histogram of the relative gray values shown in C. Data are expressed as means ± SEM (n = 3). *p < 0.05, **p < 0.01.
