Ito et al., using transcriptome data from Asian SCLC tissue samples from the GSE60052 RNA sequence dataset (n = 79) [117], examined the relationships between the four molecules and some transcription and signaling molecules and they found that SCLC-A cases were more likely to express INSM1 (insulinoma-associated protein 1), DLL3, WNT11, SOX2 (sex determining region Y [SRY]-box 2), and EZH2. Here, DLL3 is linked to small cell lung carcinoma.
