Fig. 1

NKX2-1-binding sites identified by ChIP-seq were targeted by CRISPRi that carries dCas9-KRAB and sgRNAs, which match to each binding site sequence, and the expression of NKX2-1 downstream target genes (SFTPB, LAMP3, SFTPA1, SFTPA2, MYBPH, LMO3, and CD274/PD-L1) was assessed. The putative lung function of each gene is shown. TSS transcription start site.
