We now re-analyzed the proteome by grouping the cells into SCLC-A (n = 8) versus all non-SCLC-A subtypes together (n = 18), according to the predominant expression of the respective transcription factors ASCL1 (A), NEUROD1 (N), POU2F3 (P) and YAP1 (Y). This evidence concerns the gene YAP1 and small cell lung carcinoma.
