Western blot analysis showed that the protein levels of caspase-3, caspase-9, bax, p21, CDK6 and cyclin D1 significantly restrained by si-hsa_circ_0000064, while the expression of bcl-2 notably increased in A549 and H1229 cells. Further, si-hsa_circ_0000064 also abated migration and invasion activities of A549 and H1229 cells, which may be associated with reduced expressions of MMP-2 and MMP-9. In general, our data suggest that hsa_circ_0000064 represents a novel potential biomarker and therapeutic target of lung cancer.
