Further predictions for upstream long ncRNAs (lncRNAs) in hsa-miR-340-5p indicated that AC008555.6, AC026356.1, TRHDE-AS1, and SNHG14 were the upstream lncRNAs of the has-miR-340-5p/PLAUR axis with the most potential in NSCLC. This evidence concerns the gene PLAUR and non-small cell lung carcinoma.
