Effect of DFO on the expression of caspase-3 and p-GSK3β/GSK3β proteins in mice with LPS-induced hippocampal impairment. (A-C) Protein bands on gel and their relative intensities. (D-F) The expression levels of caspase-3 and p-GSK3β/GSK3β proteins were normalized to that of β-actin as an internal control. Data are expressed as mean ± SE (n = 4–5). *P <0.05, ***P <0.001 vs. control; #P <0.05, ###P <0.001 vs. LPS. Con, control; DFO, deferoxamine; LPS, lipopolysaccharide; SE, standard error.
