Figure Lengend Snippet: Figure 5. Immunofluorescent analysis of GLUT2 and PC expression in CTX, HIPP, and BS in a mouse model of T1DM (A–C) 20 mm coronal sections of the mouse brain were stained with GLUT2 (green) and NeuN (red) and quantified in in the CTX (A), HIPP (B), and brainstem (BS) (C). Zoomed-in images are shown for the retro-splenial (RS) cortex, Cornu Ammonis 3 (CA3) of HIPP, and the DVC of BS. (D) Quantification of % positive pixels for GLUT2 using HALO software. (E–G) 20 mm coronal sections of the mouse brain were stained with pyruvate carboxylase (PC) (green) and NeuN (red) and quantified in in the CTX (E), HIPP (F), and BS (G). Zoomed-in images are shown for the RS, the CA3 of HIPP, and the DVC of BS. (H) Quantification of percentage of positive pixels for PC using HALO software. Values are presented as mean ± SEM (n = 4 biological replicates), *p < 0.05, **p < 0.01, ***p < 0.001, analyzed by Student’s t test. Scale bars are either 1 mm, 500 mm, or 100 mm. PC, pyruvate carboxylase; GLUT2, glucose transporter 2.
