PARP1 and small cell lung carcinoma: Having spotted three of them among 67 SCLCs with known sensitivities towards a broad drug library (the fourth cell line, COR-L311, was not included in the study) [36], we identified PARP inhibitors as the only class of inhibitors to which the three tuft cell-like SCLC cell lines (NCI-H211, NCI-H526, NCI-H1048) were significantly more sensitive than the non-tuft cell-like SCLC lines (Fig. 5A).
