ABCG-1 protein level in control and glycolaldehyde-treated macrophages. J774 macrophages were overloaded with oxidized LDL (50 μg/mL de DMEM) for 48 h. In the last 5h, cells were incubated with 0.25 mM glycolaldehyde (GAD; black bars) and 1 μM LXR agonist (T0901317). Control cells (C; gray bars) were incubated with T0901317 alone. Cells were scrapped into TBS containing protease inhibitors. Equal amounts of cell protein were applied into a 6% polyacrylamide electrophoresis gel and immunoblot was performed utilizing anti ABCG-1 antibody. Data (arbitrary units; n = 4) were corrected per beta-actin.
