Figure 6. Inhibition of HSP70 only inhibited downstream apoptosis-related pathways in laryngeal epithelial cells instead of in LC cells. (A and B) Western blot detected the expression of ERS-related proteins in laryngeal epithelial cells. (C and D) Western blot detected the expression of ERS-related proteins in LC cells. *p < 0.05, **p < 0.01, ***p < 0.001 vs. shRNA-NC+pepsin.
