Figure Lengend Snippet: ZnT 3 deletion is associated with a significant impairment of insulin signaling in the hippocampus. (A) Body mass analysis of ZnT 3 - / - and WT mice. *, ### Denote significant difference between groups indicated by the connector lines, p < 0.05, p < 0.001, two-way ANOVA with LSD post-hoc test. (B) Brain weight analysis of ZnT 3 - / - and WT mice. Two-way ANOVA with LSD post-hoc test. (C, D) The blood glucose levels in male (C) and female (D) mice (ZnT 3 - / - ; and WT) after fasting; n = 6 for both ZnT 3 - / - and n = 5 for both WT groups. Two-way ANOVA with LSD post-hoc test. (E, F) mRNA expression levels of Slc2a1 (GLUT1), Slc2a3 (GLUT3), and Slc2a4 (GLUT4) in cortex (E) ; and Slc2a1 (GLUT1), Slc2a3 (GLUT3), and Slc2a4 (GLUT4) and Insr (INSR) in hippocampus (F) . Expression levels are normalized to housekeeping gene Gapdh . * Denotes significant difference between groups indicated by the connector lines, p < 0.05, Mann-Whitney test. (G, H) Immunofluorescence staining of hippocampal sections of 9-months old mice. (G) : GLUT3-(red), DAPI-(blue) and GFAP (green). (H) : GLUT4-(green), DAPI-(blue) and NeuN (red). Scale bar, 50 μm; Zoom Scale bar, 5 μm. (I, J) Statistical analysis of images as those shown in (G) and (H) . * Denotes significant difference between groups indicated by the connector lines, p < 0.05, Mann-Whitney test.
