ANGPTL4 deficiency promotes macrophage lipid uptake and magnifies the induction of lipid-sensitive genes. A: Oil Red O staining of lipid droplets in RAW264.7 macrophages treated with 0.5 mM intralipid for 6 h in the presence or absence of 0.5 μg/ml recombinant ANGPTL4. B: Oil Red O staining of lipid droplets in peritoneal macrophages treated for 6 h with lymph (final triglyceride concentration of 2 mM) in the presence or absence of 0.5 μg/ml recombinant ANGPTL4. C: Microarray heat map showing expression profile of lipid-sensitive genes in peritoneal macrophages treated for 6 h with 0.5 mM intralipid in the presence or absence of recombinant ANGPTL4. D: Bodipy staining of Angptl4+/+ and Angptl4−/− BMDMs cultured with regular culture medium (Cntl) or for 6 h with 0.5 mM intralipid with or without orlistat. E, F: mRNA expression of lipid-sensitive genes in Angptl4+/+ and Angptl4−/− BMDMs treated for 6 h with 0.5 mM intralipid (E) or peritoneal macrophages treated for 6 h with lymph (final triglyceride concentration of 2 mM) (F). mRNA expression was normalized to 36b4. Data are mean ± SD from three biological replicates; *P < 0.05, **P < 0.01, and ***P < 0.001 relative to untreated WT; and #P < 0.05, ##P < 0.01, and ###P < 0.001 relative to WT + intralipid/lymph.
