PS-T reverses EMT by inducing autophagy. a MDA-MB-231 cells are treated with 5 μg/mL PS-T for 24 h. The levels of each autophagy marker in MDA-MB-231 cells are quantified using the NIH ImageJ software. (mean  ±  SD, *P  <  0.05 and ***P  <  0.001). b Confocal microscopy images of cells treated with or without PS-T (5 μg/mL) for 24 h after transfection with mRFP-GFP-LC3 plasmid (scale bars: 10 μm). Quantification of LC3-GFP and LC3-RFP puncta/cells from three independent experiments (***P  <  0.001). c MDA-MB-231 cells are treated with PS-T (5 μg/mL) for 24 h with or without LY294002 (10 µM). The levels of each EMT marker in MDA-MB-231cells were quantified using NIH ImageJ software. (mean  ±  SD, *P  <  0.05 and **P  <  0.01)
