Effects of corylin on the expression and phosphorylation of MAPKs and STAT3 in lung tissues. Expressions of phospho-JNK, JNK, phospho-ERK, ERK, phospho-p38 MAPK, p38 MAPK, phospho-STAT3 and STAT3 were analyzed by Western blot. (A) The representative blot of triplicate experiments. Quantitated results of (B) phospho-JNK/JNK ratio (n = 6), (C) phospho-ERK/ERK ratio (n = 6), (D) phospho-p38/p38 ratio (n = 6), and (E) phospho-STAT3/STAT3 ratio (n = 9~10) were shown as mean ± SEM. The relative fold of phosphorylation activity was normalized to untreated samples. (* p < 0.05, ** p < 0.01 and *** p < 0.001 vs. LPS alone).
