Across TCGA pan-cancer cohorts, FAM25E RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of FAM25E’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where FAM25E RNA is repressed in tumor relative to normal tissue. In most cancer types FAM25E is over-expressed in tumor, although a few such as STAD and LUSC show the opposite, repressed pattern.
STAD, KIRC, and LUSC are the cancer types where FAM25E tumor–normal differential expression is most reproducible.
