Effects of hispolon on (A) ER stress relative enzymes (PERK, IRE1 ATF6, GRP94, CHOP and caspase-12), (B) autophagy related enzymes (LC3-II/I and Beclin 1), (C) LKB1/CaMKK–AMPK signaling, and (D) apoptosis-related protein (Bcl-2, Bax and caspase-3) levels in the lungs of LPS challenge ALI. Lung tissue extracts were subjected to Western blot analysis using antibodies for PERK, IRE1 ATF6, GRP94, CHOP, caspase-12, LC3-II/I, Beclin 1, LKB1, CaMKK, AMPK, Bcl-2, Bax and caspase-3. Data are represented as means ± S.E.M. (n = 3). ##
