Downregulation of circ_0020123 inhibited the proliferation and migration and induced the apoptosis of NSCLC cells. a The transfection efficiency of si-circ_0020123-1 and si-circ_0020123-2 in A549 and H1299 cells was detected by qRT-PCR. b CCK-8 assay was used to detect the proliferation of A549 and H1299 cells transfected with si-circ_0020123-1 or si-circ_0020123-2. c The migration of A549 and H1299 cells transfected with si-circ_0020123-1 or si-circ_0020123-2 was measured by Transwell assay. d Flow cytolysis assay was used to detect the apoptosis of A549 and H1299 cells transfected with si-circ_0020123-1 or si-circ_0020123-2. e The protein levels of cell proliferation related protein Ki-67, cell migration related protein MMP-9 and cell apoptosis related protein Cleaved-casp9 were detected by Western blot. *P < 0.05
