Across TCGA pan-cancer cohorts, XAGE5 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of XAGE5’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where XAGE5 RNA is repressed in tumor relative to normal tissue. In most cancer types XAGE5 is over-expressed in tumor, although a few such as BRCA show the opposite, repressed pattern.
BRCA and LIHC are the cancer types where XAGE5 tumor–normal differential expression is most reproducible.
