Across TCGA pan-cancer cohorts, MSS51 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of MSS51’s most consistent transcriptional readouts.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where MSS51 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MSS51 is over-expressed in tumor, although a few such as BRCA and KICH show the opposite, repressed pattern.
LIHC, CHOL, and KIRC are the cancer types where MSS51 tumor–normal differential expression is most reproducible.
