Across TCGA pan-cancer cohorts, TRPV4 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of TRPV4’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where TRPV4 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types TRPV4 is over-expressed in tumor, although a few such as CCRCC and LUAD show the opposite, repressed pattern.
LSCC, CCRCC, and LUAD are the cancer types where TRPV4 tumor–normal differential expression is most reproducible.
