Figure Lengend Snippet: Effects of APOE4 and APOE4mut1 on 3T3-L1 adipocyte differentiation. A: Representative Western blot analysis for APOE4, APOE4mut1 in samples of culture medium collected on the 10th day of 3T3-L1 cell differentiation as well as β-tubulin in the respective cell lysates. Samples for APOE were analysed on two separate blots. B: Semiquantitative analysis of APOE4 and APOE4mut1 levels shown in the blots of panel A, normalized for β-tubulin levels (C–E) Representative images at 10× magnification of differentiated 3T3-L1 adipocytes after Oil Red O staining. The cells were induced to differentiate after infection with: (C) AdGFP, (D) AdAPOE4, (E) AdAPOE4mut1. F: Relative absorbance of Oil Red O dye, eluted from cultures infected with recombinant adenovirus. The values were derived from the average of at least three cultures for each adenovirus used. The data were analyzed using one-way ANOVA, and the values are expressed as Mean ± SEM. G: Effect of APOE4 and APOE4mut1 on triglyceride accumulation in mature 3T3-L1 adipocytes. The values for each culture were normalized to the total protein levels of the cells present in the culture. The analysis of the results was performed using one-way ANOVA, and the values are presented as Mean ± SEM. H: mRNA expression levels of the lipogenic genes ppar γ , dgat1 , and fasn as well as ppar γ effector genes adiponectin , fabp4 , fabp5 , and lpl in differentiated 3T3-L1 adipocytes expressing APOE4 and APOE4mut1. The results were normalized to the expression levels of the housekeeping rps18 gene. The analysis was performed using two-way ANOVA, and the values are presented as Mean ± SEM. ∗∗ = P < 0.005 and ∗∗∗ = P < 0.0005, n = 3 per group. Unless indicated by a horizontal line between two groups, statistical significance refers to differences among all test groups.
