circ-IARS was a circRNA derived from the exons 13–20 of the IARS gene (Figure 1a), and its expression level was higher in NSCLC cells (H1299, A549, and H460) than that in normal BEAS-2B cells (3.92 fold, 3.50 fold, and 1.64 fold, respectively, Figure 1b). The gene discussed is IARS1; the disease is non-small cell lung carcinoma.
