Across TCGA pan-cancer cohorts, C2CD5 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of C2CD5’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where C2CD5 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types C2CD5 is over-expressed in tumor, although a few such as CCRCC and LUAD show the opposite, repressed pattern.
CCRCC, LUAD, and LSCC are the cancer types where C2CD5 tumor–normal differential expression is most reproducible.
