RSG did not affect PA endocytosis. TM4 cells were pretreated with or without 20 μM RSG for 24 h, and then treated with 1 μM BODIPY FL C16 for 30 min. a Fluorescent images were captured with a fluorescence microscope (scale bar, 100 μm), and (b) the mean fluorescence intensities were quantified. Data are presented as the mean ± standard deviation of three independent experiments. ^**P < 0.01 vs. control group. N.S., not significant; RSG, rosiglitazone; PA, palmitic acid; BODIPY FL C16, 4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza-s-indacene-3-hexadecanoic acid
