To investigate whether the transcriptional profile of SMARCA4-mutant SCLC-Y lines are closely related to SMARCA4-UT or to other SCLC subtypes, we integrated RNA sequencing data from all SCLC, NSCLC, and SCCOHT cell lines in CCLE with RNA-seq data from primary tumors, including primary thoracic SMARCA4-UT, SCCOHT, and unclassified thoracic sarcomas (24). The gene discussed is SMARCA4; the disease is small cell lung carcinoma.
