Across TCGA pan-cancer cohorts, CCNYL1 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of CCNYL1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where CCNYL1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types CCNYL1 is over-expressed in tumor, although a few such as PDAC and COAD show the opposite, repressed pattern.
HNSC, LSCC, and PDAC are the cancer types where CCNYL1 tumor–normal differential expression is most reproducible.
