Across TCGA pan-cancer cohorts, ZC3H7B mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ZC3H7B’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where ZC3H7B mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types ZC3H7B is over-expressed in tumor, although a few such as PDAC and CCRCC show the opposite, repressed pattern.
HNSC, LUAD, and LSCC are the cancer types where ZC3H7B tumor–normal differential expression is most reproducible.
