In the NSCLC, studies reported that the DHX9-related circular RNAs (circRNAs) such as circ-PTEN (22) and circDCUN1D4 (23) were significantly decreased in the NSCLC tissues that promoted its progression and metastasis, which functioned by circ-PTEN/miR-155/miR-330-3p/PTEN and circDCUN1D4/HuR/TXNIP regulatory axes, respectively. Here, ELAVL1 is linked to non-small cell lung carcinoma.
