Across TCGA pan-cancer cohorts, TPRA1 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of TPRA1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where TPRA1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types TPRA1 is over-expressed in tumor, although a few such as LSCC and CCRCC show the opposite, repressed pattern.
LSCC, CCRCC, and LUAD are the cancer types where TPRA1 tumor–normal differential expression is most reproducible.
