Expression of the 6 downregulated targets in lung cancer tissue was significantly reduced (SVIL-AS1, FENDRR, ADAMTS9-AS2) or completely absent (PCAT19, LANCL1-AS1 and LINC00968) (Fig. 3) in lung cancer cell lines while positive controls (pooled normal lung tissue RNA) performed as expected in these experiments. This evidence concerns the gene PCAT19 and lung cancer.
