Autophagy regulates PPARγ expression in Caco-2 cell line. a Representative of confocal microscopy of Caco-2 cells, PPARγ (red) and DNA (blue). Reference scale bar: 25 µm. b, c The Western blot result to PPARγ expression in Caco-2 cells after 24 h’ treatments. It was used beta-actin as internal control. This data represents three independent experiments. *p < 0.05, **p < 0.005, ***p < 0.001
