Figure 7. Akt inhibitor further enhanced the inhibitory effect of hsa_circ_0018818 shRNA on progression of NSCLC. (A) The OD value of NCI-H1650 cells was detected by CCK-8 assay. (B) The apoptotic NSCLC cells were examined by flow cytometry. (C) The invasion of NSCLC cells was tested by transwell assay. **P< 0.01 vs. control. ##P< 0.01 vs. shRNA1.
