Across TCGA pan-cancer cohorts, CCDC14 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of CCDC14’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where CCDC14 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types CCDC14 is over-expressed in tumor, although a few such as CCRCC and HNSC show the opposite, repressed pattern.
CCRCC, LSCC, and LUAD are the cancer types where CCDC14 tumor–normal differential expression is most reproducible.
