Tumor necrosis factor alpha receptor 1 deficiency in hepatocytes does not protect from non-alcoholic steatohepatitis, but attenuates insulin resistance in mice

Figure 2 Effect of tumor necrosis factor alpha receptor 1 deficiency in hepatocytes on liver phenotype. A: Plasma levels of alanine amino transferase (ALT); B: Representative hematoxylin and eosin-stained liver sections; C: Relative liver weight; D: Relative amount of triglycerides normalized to liver weight. E: Total amount of hydroxyproline per liver; F: Representative Sirius Red-stained liver sections; G: Expression of the inflammatory genes interleukin 1-β (Il1-β), tumor necrosis factor alpha (Tnfα), and C-C motif chemokine ligand 2 (Ccl2). Scale bars: 200 µm. Number of biological replicates: Ctrl/tumor necrosis factor alpha receptor 1-expressing littermates (TNFR1^fl/fl) n = 9-11; fast food diet (FFD)/TNFR1^fl/fln = 19-23; Ctrl/TNFR1^ΔHEPn = 11-12; FFD/TNFR1^ΔHEPn = 19-24. Line shows mean + standard error of the mean. Significant differences are marked with (a) if P < 0.05. Ctrl: Standard chow.
