Across TCGA pan-cancer cohorts, TFAP2E mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of TFAP2E’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where TFAP2E mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types TFAP2E is over-expressed in tumor, although a few such as COAD and LUAD show the opposite, repressed pattern.
COAD, LUAD, and OV are the cancer types where TFAP2E tumor–normal differential expression is most reproducible.
