Therefore, we analyzed the expression of DUSP8 in different NSCLC cell lines (A549, H838, H1299 and H1650) and selected the cell lines for silencing based on the basal expression level of DUSP8, which was significantly higher in H838 cells than in A549, H1299 and H1650 cells (Supplementary Fig. S3J). This evidence concerns the gene DUSP8 and non-small cell lung carcinoma.
