Across TCGA pan-cancer cohorts, AHDC1 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of AHDC1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where AHDC1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types AHDC1 is over-expressed in tumor, although a few such as HNSC and COAD show the opposite, repressed pattern.
HNSC, LSCC, and CCRCC are the cancer types where AHDC1 tumor–normal differential expression is most reproducible.
