Across TCGA pan-cancer cohorts, ZC3H7A mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of ZC3H7A’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where ZC3H7A mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types ZC3H7A is over-expressed in tumor.
HNSC and LUAD are the cancer types where ZC3H7A tumor–normal differential expression is most reproducible.
