Figure 4. The effect of inhibition of HSP70 on cell viability, apoptosis and autophagy. (A and B) RT-qPCR detected the expression of HSP70 in laryngeal epithelial cells and LC cells. ***p < 0.001 vs. shRNA-NC. (C and D) CCK8 detected the viability in laryngeal epithelial cells and LC cells. (E and F) Apoptosis of laryngeal epithelial cells and LC cells were detected by flow cytometry. (G and H) The autophagy detection kit measured autophagy levels in laryngeal epithelial cells and LC cells. **p < 0.01, ***p < 0.001 vs shRNA-NC+pepsin.
