NFIB and small cell lung carcinoma: Motif enrichment analysis showed that the top two motifs enriched at DisP-seq peaks corresponded to the NFIB full site and half site (Fig. 5a) and we verified these findings by confirming NFIB precipitation by b-isox in SCLC cells (Extended Data Fig. 6e) and performing ChIP–seq for endogenous NFIB.
