Figure 1: LSD1 expression is highly overexpressed in small cell lung cancer and inversely correlated with the expression of genes encoding the antigen presentation pathway.
(A) KDM1A mRNA expression was profiled in 29 unique cancer types; data from Cancer Cell Line Encyclopedia (CCLE) (Broad, 2019) (Downloaded from cBioPortal). (B) KDM1A expression was queried in primary tumors previously analyzed in the SCLC-Atlas51, consisting of LUAD (n=24) and SCLC (n=21) clinical samples. (C) KDM1A expression was profiled at the single-cell level from the SCLC-Atlas dataset51, consisting of 54,313 SCLC transcriptomes, 3341 LUAD transcriptomes and matched normal tissues. (D) Pearson’s correlations between LSD1 (KDM1A) expression and HLA-A, HLA-B, HLA-C, B2M, TAP1, TAP2, LMP-2 (PSMB8), LMP-7 (PSMB9) from SCLC-Global (downloaded from CellMiner). Values were calculated as RNAseq RPKM (log2(value+1)).
