WT1 and non-small cell lung carcinoma: Its higher expression was also observed in NSCLC cell lines than in the normal Beas-2B and MRC-5 cell lines (Fig. 3C), and WT1 was extremely overexpressed in the high-metastatic 95D cells and L9981 cells compared with the corresponding low-metastatic 95 C cells and NL9980 cells, respectively (Fig. 3D).
