Across TCGA pan-cancer cohorts, TRERNA1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of TRERNA1’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where TRERNA1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types TRERNA1 is over-expressed in tumor, although a few such as THCA and KICH show the opposite, repressed pattern.
BRCA, COAD, and THCA are the cancer types where TRERNA1 tumor–normal differential expression is most reproducible.
