The FOXD3-AS1 expression was up-regulated in NSCLC cell lines (A549 and H1299) in comparison with NHBE cells (Fig. 1a), and further comparison showed that FOXD3-AS1 expression was up-regulated in DDP-resistant cell lines (A549/DDP and H1299/DDP) in comparison with their parental cells lines, respectively (Fig. 1a). This evidence concerns the gene FOXD3 and non-small cell lung carcinoma.
