NEUROD1 and small cell lung carcinoma: These findings align with the observation that the NE–SCLC subtype (SCLC–ASCL1) is poorly enriched in inflamed genes, while KDM6A loss promotes the transition of SCLC molecular subtype from ASCL1+ NE‐high to NEUROD1+ NE‐moderate, accompanied by an upregulation in inflammatory genes.
