Figure Lengend Snippet: Whole liver proteomics in female and male APOE3 and APOE4 mice (A) Study schematic showing primary outcomes in APOE -targeted replacement (TR) mice. n = 3 mice per group for all mouse proteomic outcomes. (B) APOE protein expression from whole liver measured via ELISA in male and female APOE3 and APOE4 mice. Statistical significance was determined by two-way ANOVA. Data are presented as mean ± SD. n = 8 mice per genotype and sex. (C) The number of differentially expressed (DE) proteins in male and female APOE3 and APOE4 mice. (D) Volcano plot showing upregulated and downregulated proteins in female APOE4 vs. APOE3 mice. (E) IPA pathway showing top 5 upregulated and downregulated pathways in female APOE4 vs. APOE3 mice. (F) Volcano plot showing upregulated and downregulated proteins in male APOE4 vs. APOE3 mice. (G) IPA pathway analysis showing top 5 upregulated and downregulated pathways in male APOE4 vs. APOE3 mice. (H) Heatmap of proteins involved in fatty acid metabolism, cholesterol and bile acid metabolism, lipid transport, and lipid storage showing upregulated and downregulated proteins between APOE4 and APOE3 mice. (I) Venn diagram showing the number of shared upregulated proteins between comparisons of female APOE4 vs. APOE3 mice and male APOE4 vs. APOE3 mice. (J) Venn diagram showing the number of downregulated proteins shared between comparisons of female APOE4 vs. APOE3 mice and male APOE4 vs. APOE3 mice. (K) Violin plot showing normalized Pgam1 protein expression from liver proteomics in male and female APOE3 and APOE4 mice. Statistical significance was determined by two-way ANOVA with Fisher’s LSD post hoc. ∗ p < 0.05. G, genotype. n = 3 mice per genotype and sex. See also .
