Effects of PD-L1-lnc on the proliferation, invasion, and apoptosis of human lung cancer cells. A549 and PC9 cells are transfected with PD-L1-lnc-expressing vector or PD-L1-lnc shRNA-expressing vector. a The proliferation of A549 and PC9 cells detected by Edu assay. b The invasion of A549 and PC9 cells detected by Transwell assay. c The apoptosis of A549 and PC9 cells detected by flow cytometry. In ac, left: representative image; right: quantitative analysis. **P < 0.01; ***P < 0.001; **** P < 0.0001. Scale bars, 100 μm
