Across TCGA pan-cancer cohorts, MYH7B mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MYH7B’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where MYH7B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types MYH7B is over-expressed in tumor, although a few such as HNSC and CCRCC show the opposite, repressed pattern.
HNSC and CCRCC are the cancer types where MYH7B tumor–normal differential expression is most reproducible.
