Across TCGA pan-cancer cohorts, HKDC1 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of HKDC1’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where HKDC1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types HKDC1 is over-expressed in tumor, although a few such as CCRCC and HNSC show the opposite, repressed pattern.
COAD, LUAD, and CCRCC are the cancer types where HKDC1 tumor–normal differential expression is most reproducible.
