To confirm whether Slug sensitizes other lung cancer cell lines to tubulin-binding agents (TBAs), we established another line of stable transfectants expressing EGFP only or EGFP and Slug using Ma1 and H1299 lung cancer cell lines (Ma1/EGFP, Ma1/Slug, H1299/EGFP, and H1299/Slug) as well as A549 cells and examined the drug sensitivity. This evidence concerns the gene SNAI2 and lung cancer.
