Figure Lengend Snippet: Rec2-exendin-4 gene therapy improves metabolic and behavioral functions in diet-induced obesity model (5 months study) (A) Body weight. (B) Total weight gain of 5 months. (C) Average food intake measured week 1–5 post AAV injection. (D) Absolute fat mass and absolute lean mass at 5 weeks post AAV injection. (E) Relative fat mass and relative lean mass at 5 weeks post AAV injection. (F) Glucose tolerance test at 6 weeks post AAV injection. (G) Area under the curve of the glucose tolerance test. (H) Open field test at 13 weeks post AAV injection. (I) Novel object recognition test at 13 weeks post AAV injection. (J) H&E staining of livers. Data are means ± SEM. Sample size: n = 5 per group. Individual values are shown in graph. Time course data (body weights and GTT) were analyzed using two-way RM-ANOVA with Sidak’s multiple comparisons test. Unpaired t test for other data analyses. ∗ p < 0.05, ∗∗ p < 0.01 , ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001. Scale bars, 100 μm.
