Fig. 3. eIF6 haploinsufficiency protects from hepatic steatosis and fibrosis and preserves insulin sensitivity.

a Growth curves of eIF6+/+ and eIF6+/− mice fed with high-fat diet, HFD (n = 12 for eIF6+/+ and n = 15 for eIF6+/−). Data are expressed as means ± SD. Two-way ANOVA. ***p value ≤ 0.001. b Body weight gain is reduced in eIF6+/− mice compared with wt ones at the indicated time points (n = 12 for eIF6+/+ and n = 14 for eIF6+/−). Two-tailed t test. Data are represented as means ± SD. c Blood triglycerides and cholesterol levels are reduced in eIF6+/− mice at the end of HFD regimen (n = 11 for genotype). Two-tailed t test. Data are represented as means ± SD. d Glucose levels in the blood: insulin tolerance test shows that eIF6+/− mice respond better to insulin administration at 120 min (n = 5 for genotype). Two-tailed t test. Data are represented as means ± SD. e Outline of the experiment. Representative images of eIF6+/+ and eIF6+/− livers are shown. Right: representative western blotting analysis of eIF6 levels in HFD-fed eIF6+/+ and eIF6+/− mice. f Liver to body weight ratio shows that eIF6+/− livers are less enlarged compared with wild-type ones at the end of HFD feeding. Two-tailed t test. Data are represented as means ± SD. (n = 18 for eIF6+/+ and n = 19 for eIF6+/−). g Representative images of liver sections: staining with Oil Red O reveals reduced lipid droplets accumulation in eIF6+/− mice compared to wild-type ones. Scale bar = 20 μm. h Collagen fibers stained with Sirius Red: liver fibrosis is reduced. Scale bar = 20 μm. i Quantification of the area stained by Oil Red O. Data are expressed as a percentage of eIF6+/+ controls. Hepatic lipid content is decreased in eIF6+/− mice. (n = 4 for genotype). Two-tailed t test. j Representative frequency distribution of lipid droplets (LDs) size. Larger LDs were detected in eIF6+/+ livers compared with eIF6+/− ones. k Quantification of area stained by Sirius Red. Hepatic fibrosis is decreased in eIF6+/− mice. (n = 3 for genotype). Data are provided as a Source Data File.
