doi: 10.1194/jlr.M021154

Figure Lengend Snippet: T7-ApoA-I binding to J774 macrophages with and without CPT-cAMP induction of ABCA1 expression. J774 macrophages were incubated 15 h with CPT-cAMP to induce ABCA1 expression. C57 or FVB recombinant T7-ApoA-I was then incubated with cells for 2 h and removed by PBS wash. A: T7-ApoA-I binding was measured by western blot of the T7-ApoA-I remaining associated with the cell protein as described in Materials and Methods. B: ABCA1 levels postincubation with 2 μg/ml C57 or FVB recombinant T7-ApoA-I as measured by ABCA1 Western blot of cell protein as described in Materials and Methods. Data points show the mean ± SD of triplicate samples.

Article Snippet: ABCA1 levels from the same samples were run on a 4–12% gradient SDS-PAGE, transferred to Immobilon, and probed with rabbit-anti-mouse ABCA1 antibody (Novus Biologicals, Littleton, CO). rHDL cholesterol esterification assay rHDL was generated from C57 or FVB T7-ApoA-I using phosphatidylcholine, T7-ApoA-I, 3 H-cholesterol, and nonlabeled cholesterol (molar ratio 200:1.2:1:1).

doi: 10.1371/journal.pone.0080089

Figure Lengend Snippet: Figure 9. MCPIP1 deficiency increased macrophage cholesterol efflux. A. Bone marrow-derived macrophages were loaded with ac-LDL and cholesterol efflux to DMEM, apoAI and HDL was measured. Data were presented as mean 6 SEM. N = 3 in each group. B. Bone marrow-derived macrophages were cultured in DMEM for 48 h with or without ac-LDL. Cell lysates were used for western blotting analysis for ABCA1 and ABCG1. Representative western blotting result was shown. C. Quantitative analysis of the western blots. Data were presented as mean 6 SEM. N = 4 in each group. Open column: WT macrophages; Black column, MCPIP12/2 macrophages. doi:10.1371/journal.pone.0080089.g009

Article Title: Dysregulated cholesterol uptake and efflux of bone marrow-derived α-SMA + macrophages contribute to atherosclerotic plaque formation

doi: 10.1007/s00018-025-05655-3

Figure Lengend Snippet: Schematic diagram illustrating the role of bone marrow-derived α-SMA + macrophages in atherosclerotic plaque formation. Macrophage-expressed α-SMA enhances SR-A expression via the AKT signaling pathway, leading to increased lipid binding and uptake. Concurrently, α-SMA suppresses ABCA1 expression, thereby reducing lipid efflux. This imbalance promotes lipid accumulation and contributes to atherosclerotic plaque formation
