Figure 5. S14G humanin (HNG) alleviated the apoptosis in lung tissues of ALI mice. (A) The protein level of apoptosis related genes was determined by western blots. (B) Analysis of protein level of Bax level. (C) Analysis of protein level of Bcl-2 level. (D) Analysis of protein level of cleaved caspase-9 level (n=6, **, P<0.05 vs. Control; &, P<0.05, 0.01 vs. LPS group).
