Across TCGA pan-cancer cohorts, CCDC85A mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of CCDC85A’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where CCDC85A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types CCDC85A is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.
LSCC, LUAD, and PDAC are the cancer types where CCDC85A tumor–normal differential expression is most reproducible.
