PPARγ regulates autophagy in Caco-2 cell line. a, b Western blot result to LC3B expression in Caco-2 cells after 24 h’ treatments. It was used beta-actin as internal control. Data represents three independent experiments. **p < 0.005, ***p < 0.0001. c The AVOs quantification by Acridine Orange staining. The relative fluorescence intensity was normalized by the unstimulated control. *p < 0.05, ***p < 0.001
