We hence first sought to examine a panel of SCLC cell lines and classified them according to their expression profile of either ASCL1 (NCI‐H69, NCI‐H146, NCI‐H510A, and SHP‐77), NEUROD1 (NCI‐H82), or both (DMS‐53) (n = 3 biological replicates) (Fig 1A). The gene discussed is ASCL1; the disease is small cell lung carcinoma.
