Effect of DFO on iron content and expression of Fn and FPN proteins in mice with LPS-induced hippocampal impairment. (A) Iron content in the hippocampus is indicated as μg per gram tissue (n = 8). (B) Protein bands on gel and their relative intensities. (C, D) The expression levels of Fn and FPN proteins were normalized to that of β-actin as an internal control in (n = 4–5). Data are expressed as mean ± SE. *P <0.05, **P <0.01, ***P <0.001 vs. control; #P <0.05, ###P <0.001 vs. LPS. Con, control; DFO, deferoxamine; LPS, lipopolysaccharide; SE, standard error.
