PD-L1, IDO-1 and B7-H4 mRNA are infrequently co-expressed in lung cancer. Histograms showing the co-expression (upper charts) and levels (lower charts) of PD-L1, IDO-1 and B7-H4 mRNA transcripts in lung cancer cases from the TCGA lung squamous carcinoma (A, N=178) and lung adenocarcinoma (B, N=230) datasets. Levels of target mRNAs were measured using RNA-sequencing in whole tissue section samples and obtained through the cBioportal analysis platform.
