A Schematic diagram of rodent model construction and sample collection. B Surgical schematic diagram of sleeve gastrectomy (SG). C Body weight after SG in two groups of mice at 2 and 4 weeks post-surgery. D Representative images of morphology and H&E and Oil Red O staining of liver tissue sections from two groups of mice at 2 weeks and 4 weeks post-surgery. Scale bar, 1 cm or 100 μm. E Comparisons of the relative area of lipid droplets among the different groups of mice at 2 weeks and 4 weeks post-surgery. F–H Serum levels of the adipokines Nrg4 (F), leptin (G), and lipocalin (H) in 2 groups of mice. n = 5. * indicates p < 0.05, 2* indicates p < 0.01, 3* indicates p < 0.001, 4* indicates p < 0.0001. The color indicates the compared group. I–K Correlation analysis between adipokine levels and the relative area of lipid droplets
