Figure 3. S14G humanin (HNG) ameliorated the inflammation in lung tissues of ALI mice. (A) mRNA level of MPO, mRNA level of IL-6, and mRNA level of TNF-α. (B) The protein level of MPO. (C) The protein level of IL-6. (D) The protein level of TNF-α (n=6, **, P<0.05 vs. Control; &, P<0.05, 0.01 vs. LPS group).
