PVT1 silencing attenuates CSE-triggered 16HBE cell apoptosis and inflammation. A RT-qPCR analysis of PVT1 expression in 16HBE cells with indicated treatments. B CCK-8 assay for evaluating cell viability. C, D Flow cytometry for detecting cell apoptosis. E Western blotting for measuring levels of apoptosis-related proteins. F, G ELISA for determining concentrations of IFN-γ and TNF-α. **p<0.01, ***p<0.001 vs. control group; ##p<0.01 vs. CSE + sh-NC group
