Cancer&Entry Information

Cancer Name	lung cancer
ICD-0-3	C34
Methods	qPCR, Western blot
Sample	lung cancer and paired normal tissues, Human lung cancer cells lines A549 and H1299
Expression Pattern	up-regulated
Function Description	hsa_circ_0000064 was up-regulated in lung cancer tissues and lung cancer cell lines (A549 and H1229). Moreover, its aberrant expression was correlated with several clinical characteristics, including T stage, lymphatic metastasis, and TNM stage. Fluorescence in situ hybridization detected that hsa_circ_0000064 was mostly located in the cytoplasm in A549 and H1229 cells. In addition, knockdown of hsa_circ_0000064 with siRNA dramatically attenuated the proliferation, blocked cell cycle progression, and promoted cell apoptosis. Western blot analysis showed that the protein levels of caspase-3, caspase9, 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
