In the original article, there was a mistake in Figure 1 as published. The Gapdh band image used in Figure 1C was from the pilot experiment. The corrected Figure 1 appears below.
Figure 1.
Expression of LCN2 in the hippocampus of diabetic mice. The expression of Lcn2 mRNA in the hippocampus at 8 w post MLDS and 4 w post HDS injection was assessed by conventional PCR (A,C). Further, the expression level of LCN2 protein in the hippocampus of STZ-induced diabetic mice was estimated by ELISA assay (B,D). Similar upregulation of Lcn2 mRNA and LCN2 protein was detected in the hippocampus at 24 w post HFD feeding (E,F). *p < 0.05 vs. the vehicle-treated control animals; Student's t-test; n = 3 for each group; data are represented as mean ± SEM. STZ, streptozotocin; MLDS, multiple low dose of STZ; HDS, high dose of STZ; HFD, high fat diet; LCN2, Lipocalin-2; w, weeks; SEM, standard error of the mean.
