We measured JMJD2C, MALAT1 level in cells through RT-qPCR and found higher JMJD2C, MALAT1 level in NSCLC cell lines (A549 and H1299) when compared with human lung bronchial epithelial cell line (BEAS-2B) (Supplementary Fig. 1A, B). This evidence concerns the gene KDM4C and non-small cell lung carcinoma.
