Background  Circular RNAs (circRNAs) participate in the genesis and progression of tumors, including non‐small cell lung cancer (NSCLC). At present, the role and regulatory mechanisms of circRNAs in NSCLC have not been fully elucidated. The aim of this study was to explore the role and regulatory mechanism of circRNA hsa_circ_0008037 (circ_0008037) in NSCLC.    Methods  Expression of circ_0008037 in NSCLC tissues and cells was detected by quantitative real‐time polymerase chain reaction (RT‐qPCR). Loss‐of‐function experiments were performed to analyze the influence of circ_0008037 knockdown on proliferation, migration, invasion, and the Warburg effect of NSCLC cells. Western blotting was utilized for protein analysis. The regulatory mechanism of circ_0008037 was surveyed by bioinformatics analysis, RNA pulldown assay, and dual‐luciferase reporter assay. Xenograft assay was used to validate the oncogenicity of circ_0008037 in NSCLC in vivo.    Results  Circ_0008037 was upregulated in NSCLC tissues and cells. Circ_0008037 downregulation reduced tumor growth in vivo and repressed proliferation, migration, invasion, and decreased the Warburg effect of NSCLC cells in vitro. Mechanically, circ_0008037 regulated nuclear ubiquitous casein kinase and cyclin‐dependent kinase substrate 1 (NUCKS1) expression via sponging miR‐433‐3p. Furthermore, MiR‐433‐3p inhibitor reversed the inhibiting influence of circ_0008037 silencing on proliferation, migration, invasion, and the Warburg effect of NSCLC cells. Also, NUCKS1 elevation overturned the repressive influence of miR‐433‐3p mimic on proliferation, migration, invasion, and the Warburg effect of NSCLC cells.    Conclusion  Circ_0008037 accelerated tumor growth and elevated the Warburg effect via regulating NUCKS1 expression by adsorbing miR‐433‐3p, providing an underlying target for NSCLC treatment.
