(A–F) “Obesity/IR only” model: WT C57BL/6 mice were fed a low-fat diet (LFD) or high-fat diet (HFD) for 9 weeks. “HC ± obesity/IR” models: Ldlr−/− mice were fed a chow diet, a Western-type diet (WTD), or a high-cholesterol-low-fat (HCLF) diet for 12 weeks.
(A) Metabolic parameters.
(B) Proteomics analysis of peritoneal macrophages. Differentially abundant proteins (yellow, up; blue, down) were identified based on the G-test (G > 1.5) and t test (p < 0.05).
(C) Oil-red-O staining of peritoneal macrophages.
(D) Cholesterol levels in peritoneal macrophages treated with/without 2% serum from WTD-fed Ldlr−/− mice.
(E) Cholesterol levels in peritoneal macrophages.
(F) Aortic root lesion area.
Results are mean ± SEM. *p < 0.05 (t test). n = 5–10 mice/group. See also Figures S1 and S2 and Table S1.
