Figure 4. Constitutively active Gli2 prevents HFD-induced obesity and improves glucose metabolism.
(A) A schematic for experimental design. E0: embryonic day 0; P0: postnatal day 0; 2M: 2 months of age. (B) Representative images after 8 weeks of HFD. (C) Measurements of body weight. (D) Measurements of body composition after 8 weeks of HFD. (E, F) Whole-mount images (upper) and histology (lower) of gonadal white fat (E) or interscapular brown fat (F) after 8 weeks of HFD. (G) Detection of bone marrow fat by perilipin immunofluorescence staining after 8 weeks on HFD. Boxed regions shown at higher magnification in insets. (H, I) Detection of gene expression by qPCR in WAT (G) and BAT (H) after 8 weeks on HFD. (J, K) Glucose tolerance test (GTT) (I) and insulin tolerance test (ITT) (J) after 8 weeks on HFD. *p<0.05, n = 5 mice, males. Females show similar results. Black scale bar: 100 μm; white scale bar: 200 μm.
