Levels of the protein expression (upper panel) of (A) Bax, (B) Bcl-2, (C) cytochrome-c and (D) cleaved caspase-3 in the hippocampus of the normoxic (Nx) or hypoxic (IH) groups; LBP-treated hypoxic (IH+LBP) or normoxic (Nx+LBP) groups are summarized. β-actin was an internal control. Data are mean ± SEM (n = 6–8). For Bax, *p < 0.05 when compared with Nx, #p < 0.05 when compared with IH+LBP, $p < 0.05 when compared with Nx+LBP groups, ^p < 0.05 when compared with Nx, !p < 0.05 when compared with Nx+LBP. For Bcl-2, cytochrome-c and cleaved caspase 3, *p < 0.05 when compared with Nx, #p < 0.05 when compared with IH+LBP, $p < 0.05 when compared with Nx+LBP groups.
