Circ_0000808 was overexpressed in NSCLC tissues and cells. A The basic information of circ_0000808 was shown. B The expression of circ_0000808 in NSCLC tumor tissues and adjacent normal tissues was measured by qRT-PCR. C The expression of circ_0000808 was examined by qRT-PCR in tumor tissues of NSCLC patients with different TNM stages. D QRT-PCR was used to measure circ_0000808 expression in tumor tissues of patients with or without lymph node metastasis. E The circ_0000808 expression in NSCLC cells (PC9, HCC827, A549, and NCI-H1299) and BEAS-2B cells was detected by qRT-PCR. RNase R assay (F) and ActD assay (G) were performed to assess the circular characteristic of circ_0000808. **P < 0.01, ***P < 0.001
