Abstract

Accumulating evidence indicates that circular (circ)RNAs exhibit complex functions in diverse malignant tumors, including non‑small cell lung cancer (NSCLC). The role of the circRNA transcription adaptor 2A (circTADA2A) in NSCLC remains unclear. The expression, function and mechanism of circTADA2A in NSCLC development were investigated in the present study. The results revealed that circTADA2A was upregulated in NSCLC, and that knockdown of circTADA2A inhibited cell proliferation and migration in the NSCLC cell lines A549 and H1299. Functional assays demonstrated that circTADA2A promoted proliferation and migration via interacting with microRNA (miR)‑638. Bioinformatics and reverse transcription‑quantitative PCR assay confirmed that miR‑638 was expressed at low levels in NSCLC. In addition, it was found that miR‑638 served a tumor‑suppressive role and suppressed proliferation and migration via PCNA clamp associated factor (KIAA0101) inhibition in A549 and H1299 cells. Lastly, it was verified that circTADA2A promoted cell proliferation and migration, at least partially, via miR‑638/KIAA0101 signaling in A549 and H1299 cells. In summary, the present study showed that circTADA2A promoted NSCLC cell proliferation and migration via modulating miR‑638/KIAA0101 signaling.
