Across TCGA pan-cancer cohorts, ECM2 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ECM2’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where ECM2 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types ECM2 is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.
CCRCC, PDAC, and LSCC are the cancer types where ECM2 tumor–normal differential expression is most reproducible.
