Across TCGA pan-cancer cohorts, MYO9A mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of MYO9A’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where MYO9A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types MYO9A is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.
LSCC, LUAD, and CCRCC are the cancer types where MYO9A tumor–normal differential expression is most reproducible.
