Abstrakt: Non‐small cell lung cancer (NSCLC) is one of the most common malignant tumors worldwide. Circular RNAs (circRNAs) have been widely reported to play a role in the pathogenesis of various tumors. Nevertheless, the function of circ_0001955 in NSCLC progression has not been explored yet. This study aims to explore the functions of circ_0001955 in NSCLC and investigate its regulatory molecular mechanism. First, we determined that circ_0001955 was upregulated in NSCLC cells. Subsequently, we demonstrated that knockdown of circ_0001955 restrained cell proliferation and invasion. In vivo experiments further proved the suppressive effect of circ_0001955 silence on tumor growth. Mechanism assays revealed that circ_0001955 enhanced nuclear factor‐κB (NF‐κB) inhibitor interacting Ras‐like protein 2 (NKIRAS2) expression by sponging microRNA‐29a‐3p (miR‐29a‐3p). Upregulation of NKIRAS2 led to the deceased level of IκBβ but increased levels of nuclear p65, thus activating the NF‐κB signaling pathway. In conclusion, Circ_0001955 activates the NF‐κB pathway to promote NSCLC cell proliferation and invasion by regulating miR‐29a‐3p/NKIRAS2 axis. [ABSTRACT FROM AUTHOR]
