Across TCGA pan-cancer cohorts, MVD mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MVD’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where MVD mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types MVD is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
CCRCC, PDAC, and COAD are the cancer types where MVD tumor–normal differential expression is most reproducible.
