Across TCGA pan-cancer cohorts, IL36A mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of IL36A’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where IL36A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types IL36A is over-expressed in tumor, although a few such as HNSC show the opposite, repressed pattern.
HNSC are the cancer types where IL36A tumor–normal differential expression is most reproducible.
