Thus, the strongly ABCC1- and LRP-overexpressing small cell lung cancer GLC4/ADR (Figure 4B) and the colchicine-selected, ABCB1-overexpressing, HeLa cell subclone KB-C-1, were equally sensitive against hellebrigenin as their parental cell lines (Figure 4C). This evidence concerns the gene ABCB1 and small cell lung carcinoma.
