Across TCGA pan-cancer cohorts, ETDB RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of ETDB’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where ETDB RNA is repressed in tumor relative to normal tissue. In most cancer types ETDB is over-expressed in tumor, although a few such as LUSC show the opposite, repressed pattern.
LUSC are the cancer types where ETDB tumor–normal differential expression is most reproducible.
