Across TCGA pan-cancer cohorts, LBX1 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of LBX1’s most consistent transcriptional readouts.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where LBX1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types LBX1 is over-expressed in tumor, although a few such as HNSC and LUAD show the opposite, repressed pattern.
BLCA, HNSC, and LUAD are the cancer types where LBX1 tumor–normal differential expression is most reproducible.
