Across TCGA pan-cancer cohorts, MT1G mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MT1G’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where MT1G mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types MT1G is over-expressed in tumor, although a few such as CCRCC and PDAC show the opposite, repressed pattern.
CCRCC, PDAC, and LSCC are the cancer types where MT1G tumor–normal differential expression is most reproducible.
