Across TCGA pan-cancer cohorts, CARD14 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of CARD14’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where CARD14 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types CARD14 is over-expressed in tumor, although a few such as HNSC show the opposite, repressed pattern.
HNSC and LSCC are the cancer types where CARD14 tumor–normal differential expression is most reproducible.
