Across TCGA pan-cancer cohorts, FA2H mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of FA2H’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where FA2H mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types FA2H is over-expressed in tumor, although a few such as LSCC show the opposite, repressed pattern.
COAD, LUAD, and PDAC are the cancer types where FA2H tumor–normal differential expression is most reproducible.
