Across TCGA pan-cancer cohorts, R3HCC1L mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of R3HCC1L’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where R3HCC1L mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types R3HCC1L is over-expressed in tumor, although a few such as LUAD and HNSC show the opposite, repressed pattern.
CCRCC, LUAD, and HNSC are the cancer types where R3HCC1L tumor–normal differential expression is most reproducible.
