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