Across TCGA pan-cancer cohorts, HEMGN mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of HEMGN’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where HEMGN mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types HEMGN is over-expressed in tumor, although a few such as PDAC and LSCC show the opposite, repressed pattern.
LUAD, PDAC, and LSCC are the cancer types where HEMGN tumor–normal differential expression is most reproducible.
