Figure 1. Pepsin inhibited viability while promoted apoptosis and autophagy in laryngeal epithelial cells and LC cells. (A and B) CCK8 detected the viability in laryngeal epithelial cells and LC cells. (C and D) Apoptosis of laryngeal epithelial cells and LC cells were detected by flow cytometry. (E and F) The autophagy detection kit measured autophagy levels. *p < 0.05, **p < 0.01, ***p < 0.001 vs. Control.
