In order to investigate the efficacy of ROR1 inhibition in vitro, we characterized 8 SCLC cell lines (H69, H82, H146, H187, H209, H211, H1417, and H1963) for ROR1 and BCL2 expression (Fig. 2B), normalizing gene expression to GAPDH. This evidence concerns the gene GAPDH and small cell lung carcinoma.
